Definitions
- this invention relates to implantable medical devices, their manufacture, and methods of use. Some embodiments are directed to delivery systems, such as catheter systems of all types, which are utilized in the delivery of such devices.
- Balloon catheters are employed in a variety of medical procedures.
- One such procedure is angioplasty which is a well known medical practice used in the treatment of diseased arteries hi the vasculature of a patient.
- angioplasty procedures alone, however, involves a risk of restenosis of the artery, which may necessitate another angioplasty procedure, a surgical bypass procedure, or some method of repairing or strengthening the area. Therefore, it has become more common practice to use a catheter-delivered stent to prevent restenosis and to reinforce and strengthen weakened vessel walls.
- a stent is a medical device introduced to a body lumen and is well known in the art.
- Stents, grafts, stent-grafts, vena cava filters, expandable frameworks, and similar implantable medical devices, collectively referred to hereinafter as stents are radially expandable endoprostheses which are typically intravascular implants capable of being implanted transluminally and enlarged radially after being introduced percutaneously.
- a stent is implanted in a blood vessel at the site of a stenosis or aneurysm endoluminally, i.e.
- minimally invasive techniques in which the stent in a radially reduced configuration, optionally restrained in a radially compressed configuration by a sheath and/or catheter, is delivered by a stent delivery system or "introducer" to the site where it is required.
- the introducer may enter the body from an access location outside the body, such as through the patient's skin, or by a "cut down” technique in which the entiy blood vessel is exposed by minor surgical means.
- stents After being introduced percutaneously, stents can be expanded by an internal radial force, such as when mounted on an inflatable balloon. Stents can also be self-expanding or a combination of self-expanding and balloon expandable (hybrid expandable). Stents may be implanted to prevent restenosis following angioplasty in the vascular system. Stents may be expanded and implanted in a variety of body lumens or vessels such as within the vascular system, urinary tracts, bile ducts, fallopian tubes, coronary vessels, secondary vessels, etc. A number of complications arise when stenoses form at vessel bifurcation sites.
- a bifurcation site is an area of the vasculature or other portion of the body where a first (or parent) vessel is bifurcated into two or more branch vessels.
- a stenotic lesion or lesions form at such a bifurcation, the lesion(s) can affect only one of the vessels (i.e., either of the branch vessels or the parent vessel) two of the vessels, or all three vessels.
- One complication involves irregular folding of the balloon or balloon portion which pushes against and moves that portion of the stent which expands into the vessel bifurcation. While auxiliary portions of a delivery system have been successful in expanding portions of stents into a side branch vessel, there remains a need for devices that are particularly suitable for expanding stents at a bifurcation to achieve an ideal expanded configuration.
- This invention contemplates a number of embodiments where any one, any combination of some, or all of the embodiments can be incorporated into a stent and/or a stent delivery system and/or a method of use.
- the present invention relates to novel folding arrangement for inflation balloons.
- the inflation balloons are folded in a systematic pattern which aids in the proper deployment of the side branch assembly of the stent.
- the improved folding arrangement aids in the deployment of the extending members relative to the bifurcated vessel wall.
- At least one embodiment of the invention is directed to a balloon catheter comprising a balloon inflation system.
- the balloon inflation system has a side branch balloon structure capable of at least partially expanding a side branch structure of a bifurcated stent When in an un-inflated configuration, the side branch balloon structure is folded in a pattern which permits orderly unfolding when the side branch is inflated.
- Contemplated embodiments include a main branch balloon structure capable of inflating a main tubular body of a bifurcated stent which is either in or not in fluid communication with the side branch balloon structure.
- At least one embodiment of the invention is directed to a side branch balloon structure comprising a radial end, a luminal end, and a side portion extending between the radial and luminal ends.
- the radial end When in the inflated configuration, the radial end is further away from the main branch central axis than the luminal end, and when in the un-inflated configuration the radial and luminal ends are substantially adjacent to each other.
- the side branch balloon structure can be folded such that: at least some of the side portion lies flush against and over the radial end, at least some of the side portion is further folded into pleats, and/or at least some of the side portion is further folded into overlapping folds.
- the side portion can also be folded such that: it is folded into three or more segments with overlapping regions between the folded segments, at least one segment lies above one overlapping region and beneath one overlapping region, every folded segment lies above one overlapping region and beneath one overlapping region, at least some of the overlapping folds are of different sizes, at least some of the pleats are of different sizes, and/or the pattern is generally uniform about a side branch axis.
- At least one embodiment of the invention is directed to a balloon catheter further comprising a catheter shaft disposed about which is a bifurcated stent.
- the bifurcated stent has a main tubular body and a side branch structure having an iris and a crown configuration.
- When in the crown configuration at least a portion of the side branch assembly defines a fluid lumen in fluid communication with main tubular body and extends away from the main tubular body at an oblique angle.
- When in the iris coirfiguration at least a portion of the side branch assembly is positioned adjacent to the orderly folded side branch balloon structure.
- the side branch assembly can also comprise one or more petals which when crowned define at least a portion of the second fluid lumen.
- the folded pattern results in the positioning of smooth portions of the side branch balloon structure against the petals. These smooth portions can be without folds and can cause a portion of the side branch balloon structure to inflate in a sweeping rotational motion.
- the pattern can allow for at least a portion of the side branch balloon structure to inflate by first primarily expanding in a circumferential direction away from a center of the side branch balloon structure and later primarily expanding in a radial direction.
- At least one embodiment of the invention is directed to a method of folding a side branch balloon structure comprising the steps of: forming a cup by folding a radial end of the a side branch balloon structure into a luminal end of the side branch balloon structure and forming a discus by smoothly folding down the most radial portion of the cup against the radial end of the side branch balloon structure.
- the method can further including the steps of: inflating the side branch balloon, deflating the side branch balloon, and crimping an unexpanded side branch assembly of an unexpanded bifurcated stent over the folded side branch balloon structure.

- Embodiments of the invention are directed to folding arrangements of both multiple lumen type and single lumen type balloon catheters.
- FIG. 1 there is shown a multiple balloon type catheter (2) along whose main catheter shaft (7) is an expanded side balloon structure (5).
- FIG. 2 shows disposed about the inflated side balloon structure (5) and the inflated main catheter balloon (3) a bifurcated stent (1) in an expanded state.
- Some examples of multiple lumen catheters are discussed in published US Patent Publication Nos. US 2003/0163082, US 2005/0015108A1, and US 2005/0102019Al and co-pending, concurrently filed, and commonly owned U.S. Application having an Attorney Docket Number of S63.2B-13216-US01 the entire disclosure of which are incorporated herein by reference in their entirety.
- the multiple lumen type balloon catheter (2) comprises at least two balloons.
- One is the main catheter balloon (3) and the other is the side branch balloon (6).
- the side branch balloon (6) comprises a side balloon structure (5) in fluid communication with a side inflation lumen (8).
- Some examples of single balloon type balloon catheters are discussed in published US Patent Publication No. US 2004/0138737 Al the entire disclosure of which is incorporated herein by reference in its entirety.
- integrated into the material of the main catheter balloon is a blister or bulge which defines the side balloon structure (5). As the main catheter balloon is inflated, its side balloon structure (5) inflates as well.
- the stent (1) comprises two portions, a generally tubular main stent body (10) which defines a primary fluid lumen (14) and a side branch assembly (30).
- the stent (1) has an expanded and an unexpanded state. When in the expanded state, the stent (1) assumes a greater volume than when in the unexpanded state.
- the main stent body or main branch (10) of the bifurcated stent (1) extends about a main branch central axis (16).
- the main stent body (10) can be expanded by pressure applied to the inner surface of the main stent body (10) by the inflation of the main catheter balloon (3), it can be inflated by a self-expansion mechanism, or it can be expanded by some combination of the two.
- the side branch assembly or side branch (30) forms a bifurcating side branch which defines a secondary fluid lumen (34) in fluid communication with the primary fluid lumen (14).
- the side branch assembly extends about a side branch axis (46).
- This side branch is capable of extending in a radial direction (31) out of the parent vessel and into the branch vessel.
- the side branch assembly (30) comprises one or more petals (32).
- the definition of the term "petal” is one or more side branch members capable of twisting, bending, pivoting or otherwise opening to define the second fluid lumen (34) by opening away from the tubular shape defined by the generally tubular structure of the outer surface of the first stent body (10).
- side branch assemblies can also comprises non-petal structures. As a result, all embodiments in this application which describe petals will be understood to contemplate non-petal type side branch assemblies as well.
- the petals (32) can be arranged in an iris configuration when the stent (1) is unexpanded and in a crown configuration when the stent (1) is expanded.
- iris is when one or more petals (32) are generally lying along the tubular shape defined by the generally tubular structure of the outer surface of the first stent body (10) and are covering at least a portion of a side branch opening (18) in the main stent body (10).
- the definition of the term “crown” is when as at least one petal (32) are positioned at an oblique angle radially displaced from the tubular shape defined by the generally tubular structure of the outer surface of the first stent body (10).
- oblique is an angle of greater than zero degrees, such as an angle of between about 1 and about 180 degrees.
- An oblique angle explicitly includes angles of both exactly and about 90 degrees.
- the side balloon structure (5) Before expansion, when in the unexpanded state, the side balloon structure (5) is in an un-inflated configuration.
- this un-inflated configuration is the result of deflation and/or the application of a generally untargeted force in the luminal (towards the stent lumen) direction (35) or one or more generally untargeted forces along at least a portion of the radial end (60), the luminal end (59), and/or the side length (58) of the side balloon structure (5) (as shown in FIG. 3), the un- inflated balloon assumes an irregular shape.
- FIG. 4 illustrates, simple compressive force causes the balloon folds (57) and the overall assumed shape to be randomly formed due to the inconsistent and random budding and pleating that takes place within the balloon material.
- the side balloon structure (5) when in the unexpanded state is configured according to an organized arrangement.
- FIG. 6 there is shown one such organized arrangement, the "cup" arrangement.
- the side balloon structure (5) is in the cup arrangement, at least a portion of the inner surface of the radial end (60a) and the inner surface of the luminal end (59) are substantially flush with one another.
- at least a portion of the inner side of the upper ends of the side lengths (58a") and the inner side of the lower ends of the side lengths (58a ! ) are also substantially flush with one another.
- the cup arrangement is characterized by a folded interface (56) being formed between the upper and lower ends of the side balloon structure.
- the cup arrangement is formed by the application of a compressive force in the luminal direction (35) evenly distributed along the entirety of the radial end (60) and vectored towards the luminal end (59).
- This force can be applied in combination with a mandrel which keeps the side lengths (58) straight and rigid.
- This applied force will cause a folded interface to form between that portion of the side length (58) that is pushed internal to the inner side of the lower ends of the side lengths (58a') and that portion which remains external to the inner side of the lower ends of the side lengths (58a').
- a lip (29) forms.
- the cup arrangement is formed by the application of a luminally directed (35) force focused towards the center of the radial end (60) of the side balloon structure (5), This focused force cooperates with a side directed force that pushes that portion of the upper end of the balloon material internal to the inner side of the lower ends of the side lengths (58a') to be flush with the inner side of the lower ends of the side lengths (58a').
- the side balloon structure (5) can folded while, before, or after the main stent body inflating balloon or balloon portion is inflated or collapsed.
- FIG. 7 there is shown at least one embodiment of the invention where at least some of the upper ends of the side lengths (58a" and 58b") and lower ends of the side lengths (58a' and 58b') are folded according to a "discus" arrangement.
- the discus arrangement can be cooperative with a cup arrangement or independently arranged.
- at least a portion of the outer surface of the upper end of the side length (58a") is folded in such a manner that it lies flush against the outer surface of the radial end (60b).
- the discus arrangement in the side balloon structure (5) has generally organized arrangement of pleats (40) in the folded balloon material. These pleats (40) can be evenly spaced about the compressed side balloon structure (5). Because those portions of the balloon material closer to the center of the side balloon structure (5) have less area for their material to be spread about, the pleats (40) are present in portions of the balloon material closer to the center of the side balloon structure (5). Referring now to FIGs 10 and 11, it can be understood because the pleats allow for overlap of balloon material in the smaller central region of the side balloon structure (5) in the discus arrangement, they can be located at or near the lip (29) between the upper and lower ends of the side length of the side balloon structure (5).
- FIGs. 14 and 15 at least a portion of the side balloon structure (5) is in a discus arrangement where the overlapping folds of material (27) are in an inter-layered arrangement.
- FIG. 14 illustrates a top down view of this structure and FIG. 15 delineates with phantom lines the covered folded segments of balloon material (20).
- inter-layered is defined as an arrangement in which one side of an object is positioned above the adjacent side of a first adjacent object and the other opposite side of the object is positioned below the adjacent side of a second adjacent object.
- each inter-layered segment radially pushes the adjacent segment reducing the overall energy needed to radially push all of the segments.
- the arrangements cause the segments to move in a rotational direction (43).
- This rotational direction (43) provides a precisely directed pushing force against the crowning side branch assembly, and by sweeping each of the petals in a different tangential direction, reduces the likelihood of petals colliding with each other when crowning.
- the phantom lines in FIG. 15 shown at least one embodiment where the overlapping regions (41) become progressively smaller the further they are from the center of the side balloon structure (5).
- FIG. 16 there are shown an embodiment in which the discus arrangement features a plurality of evenly spaced pleats (40).
- the evenly spaced pleats (40) when inflated at least partially push the petals in different direction reducing the likelihood of petal collisions.
- FIGs. 17 and 18 illustrate embodiments having combinations of the features of FIGs. 14 and 16.
- FIGs. 17 and 18 show both one or more pleats (40) and one or more folded overlapping regions (41).
- FIGs. 17 and 18 show that if one segment (20) of balloon material has a highly overlapping region at one end (45") it can also have a less overlapping region (45') at the other end of that segment. Modifying the degree of overlap at different segment ends allows for modulation in the rotational sweep and speed with which different portions of the side balloon structure (5) will attain during inflation. Such modulation facilitates expansion of irregularly shaped side branch structures.
- the various flush and even folding arrangements impart a number of advantages to the inflation process of the side balloon structure (5).
- One advantage is that the folding arrangement allows for control over the sequence of the inflation of particular portions of the side balloon structure allowing forces to be applied in a desired sequence.
- Another advantage is that they allow for the smooth and even expansion of the outer surface of the radial end (60b) as it moves radially (31) away from the luminal end (59).
- the organized unfolding that the side balloon undergoes has a predictable sweeping motion which is cooperative with the crowning motion of the petals.
- This predictable sweeping motion reduces or prevents shear forces which can be caused by erratic motion that accompanies the inflation induced smoothing out of erratically shaped fold lines and erratically positioned portions of the side balloon structure (5).
- the sweeping motion with which the organized folds and pleats unfold when expanded also reduces wasted inflation energy that would otherwise accompany untangling and untwisting erratically positioned portions of the side balloon structure (5).
- the organized folding designs are also rep eatable and can be easily integrated into industrial production lines.
- the organized structures reduce the likelihood of unwanted volume producing voids occupying the side branch structure (5) reducing its overall profile.
- FIGs 19-23 illustrate one embodiment in which the precise pushing force is applied efficiently to petals (32), other portions of the side branch assembly (30), other portions of the balloon, or any other object positioned over the side balloon structure (5)
- FIGs. 19-23 there is shown at least one embodiment of a side balloon structure (5) having a cup and discus arrangement where the blunt unfocused radial force that the inflation of the side balloon structure (5) of FIG 4 would produce is replaced by an orderly, sequential, and precisely directed series of forces.
- the side balloon structure (5) inflates, first the discus arrangement at least partially unfolds, after which the cup arrangement is rearranged as the balloons volume is increased.
- the folded side balloon structure (5) prior to inflation, has a low cross sectional profile.
- FIG. 19 illustrates a volume void between the folded side lengths equal to the volume of the lengths it will be understood that significantly greater or lesser void volumes are contemplated by tins invention.
- the radial bulge (36) is more luminal at its center than an its edges, the radial bulge (36) applies more pushing force against the petal summit (38) and less against the petal base (42) providing torque which is highly cooperative to the bending and twisting motion needed for successful crowning.
- the folding arrangement limits the allowed initial motions to the side lengths (58) in an outwardly directed arced path there is a greatly reduced the amount of friction, rubbing or chaffing between the petal and the unfolding side balloon structure (5).
- the petals (32) begin to bend outward (and away from majority of the mass of the side branch structure(5)) at the very beginning of the inflation process, the likelihood of an erratic motion by a portion of the balloon deforming, distorting, or otherwise improperly extending the side branch assembly becomes reduced.
- the petals develop outwardly directed momentum which reduces the overall energy needed to extend the petals (32).
- FIG. 22 there is shown that after the discus arrangement becomes somewhat unfolded the cup arrangement then becomes unfolded as well.
- the radially directed (31) force described in FIGs. 19, 20, and 21 declines and is replaced by outward a force directed in outward directions (37) parallel to axes extending from the center of the side opening (18) to the main stent body (10).
- This gradual replacement of the radially directed force with the outwardly directed force is complimentary to the direction vector of the petals as they gradually transition from a substantially iris configuration to a substantially crowned configuration.
- the petal tips (38) arc from a primarily radial trajectory (31 of FIG. 20) to a primarily outward trajectory (37) the sequence of inflation matches the motion of the petals resulting in highly efficient inflation system.
- the radial side (60) is thinner than (60) the side length (58), By folding the side balloon structure (60) into discus arrangements, the thicker of the materials abuts the side branch assembly (30) reducing the likelihood that a portion of balloon will be ruptured or otherwise damaged by impacting against the side branch assembly (30).
- FIGs. 24 and 25 there is shown the main catheter balloon (3) and the side balloon structure (5), The main catheter balloon (3) and the side balloon structure (5) are in fluid communication which allows the main catheter balloon (3) and the side balloon structure (5) to undergo common inflation and deflation.
- FIG. 24 illustrates a balloon catheter (2) in the unexpanded state and FIG.
- FIGS. 25 show inflation lumens at the distal and proximal sides of the side balloon structure (5) which can apply inflating fluid to different portions of the folded side balloon structure (5).
- Embodiments contemplated by this invention include catheters in which the main catheter balloon (3) and the side balloon structure (5) are linked to different fluid sources which allows them to undergo independent inflation and deflation. Similarly two or more inflation lumens can be positioned at locations about the side balloon structure (5). These inflation lumens need not only be distal to or proximal to the side balloon structure and can be positioned above, below, or at any position around the side balloon structure (5). Depending on the desired sequences of inflation, the catheter may be configured so that each inflation lumen can be independently filled.
- the inflation lumens may be configured to be in common fluidic communication with one or more of the other inflation lumens.
- one or more inflation lumens may be independent to provide for the withdrawal of fluid from the side balloon structure (5) or may utilize valves to only allow fluid to pass once a desired pressure level is present within the side balloon structure (5) and/or within the inflation lumen. Coordination of the order of inflation, inflation pressure, fluid flux, and fluid flow directions can be combined with the other inflation embodiments disclosed in this application to facilitate the efficient and successful inflation of the side balloon structure (5).
- At least one of one or more fluid lumens are positioned directly against or immediately adjacent to one or more balloon portions including but not limited to: a lip, a folded segment, a pleat, a radial end, a luminal end, a side length, a inner side of a side length, an outer side of a side length, an upper end of a side of a side length, a lower end of a side length, or any combination thereof to facilitate its displacement prior to the displacement by inflation fluid of another second portion of the side balloon structure (5).
- Sequential displacement can be accomplished by the sequential flow of fluid through a number of specifically positioned lumens against specific side balloon structure portions. Such coordinated inflation can cause or cooperatively facilitate rotationally directed movement and momentum within the inflating side balloon structure (5).
- the stent, its delivery system, or other portion of an assembly may include one or more areas, bands, coatings, members, etc. that are detectable by imaging modalities such as X-Ray, MRI, ultrasound, etc.
- imaging modalities such as X-Ray, MRI, ultrasound, etc.
