They are usually inserted while they have a first relatively small diameter and implanted in a desired area, for example inside a vessel, then the stent is expanded in situ until it reaches a second diameter larger than the first diameter.

Description
- The present invention relates to a new type of stent for transluminal implantation and in particular new vascular stents.
- Stents for transluminal implantation are well known. They are generally comprised of metallic supports which are inserted into a part of the human body such as bile ducts, the urinary system, the digestive tube and notably by percutaneous route inside the blood vessels, usually the arteries in which case they are typically termed vascular stents. Stents are usually generally cylindrical and are constructed and arranged to expand radially once in position within the body. They are usually inserted while they have a first relatively small diameter and implanted in a desired area, for example inside a vessel, then the stent is expanded in situ until it reaches a second diameter larger than the first diameter. A balloon associated with the catheter is usually used to provide the necessary interior radial force to the stent to cause it to expand radially. Self-expanding stents are also known which can expand from a first diameter to a larger second diameter without the use of a means for applying an interior radial force, such as a balloon, to them. One such type of self-expanding stent is a stent made of a shape memory metal which expands to its second larger diameter upon exposure to body temperature. Such stents are also known.
- The present invention proposes a novel type of stent which combines a self-expanding part or portion with a part or portion which requires an interior radial force for expansion. More specifically, a stent for transluminal implantation according to the present invention will comprise cylindrical parts preferably in juxtaposition, with at least one part being self-expanding whereas another part requires an interior radial force for its expansion, such as a balloon catheter or the like. Basically, the stent will consist of at least two of the aforementioned parts but may consist of more than two parts. Such an arrangement enables improved placement of the stent by providing immediate expansion in part upon release of the stent from its delivery catheter.

FIG. 2 is a schematic showing of a stent similar to that ofFIG. 1 on a delivery catheter; -
FIG. 3 is a schematic showing of the delivery system ofFIG. 2 with the stent released for implantation; -
FIGS. 4 and 5 are schematic-showings of a stent of the invention used in a vessel branching situation; and -
FIG. 6 is a showing of another embodiment of a stent according to the invention, and -
FIGS. 7-10 are schematic showings of bifurcated stents making use of the invention. -
FIG. 1 shows a stent which combines self-expanding characteristics and balloon expandable characteristics, i.e., requires expansion by use of a radial interior force. Preferably, the stent will have the self-expandingpart 12 joined at one end in juxtaposition to the proximal end of a balloonexpandable stent 14. The parts of the stent may be formed in accordance with any of the known stents extant in the prior art. Preferably however, the self-expandingpart 12 will be of a shape memory metal such as nitinol so as to enable self-expansion at body temperature upon release of the stent from its delivery catheter (not shown). The immediate expansion ofpart 12 aids in placement of the stent during release, following which a balloon or the like may be used to expandpart 14. -
Part 12 may be of a larger diameter, or it may be flared. to provide the earliest possible contact with the body portion into which it is inserted, such as a vessel. This is best seen for example inFIGS. 2 and 3 which show astent 10 similar to that ofFIG. 1 on a delivery catheter.FIG. 2 shows the stent having the twoparts Part 12 is the self-expanding part whilepart 14 requires a separate force for expansion such as aballoon 16 of a delivery catheter generally indicated at 18 inside the stent. InFIG. 2 , the stent is shown prior to release or deployment, the self-expanding part is enclosed by aretractable sheath 20. InFIG. 3 , the sheath has been retracted, allowing self-expandingpart 12 to flare-outwardly. Subsequently,balloon 16 may be used in the known manner to expandpart 14. - Since most stent delivery catheters include a retractable sheath which exposes the stent for implantation and removal from the catheter, if the self-expanding
part 12 is placed on the proximal end of the stent as shown, it will most likely be able to lock the stent in place until the remainder of the stent is expanded as by balloon expansion. This placement is preferable although placement in other parts of the stent proper may also be used. - When the self-expanding portion is placed at the proximal end of the stent, such a stent is particularly useful in vessel stenting in which the vessel is of the bifurcating or branching type. Such a stent is shown schematically in
FIGS. 4 and 5 at 10.FIG. 4 shows the stent having aproximal end part 12 which is self-expanding while the remainder of thestent body 14 is balloon expandable byballoon 16 oncatheter 18. InFIG. 4 , the retractable sheath has been removed allowing the self-expanding part to expand at theostium 22 in avessel 24 branching off of a main vessel such asaorta 26, helping to more accurately place the stent.FIG. 5 shows the stent after expansion ofpart 14 by the balloon catheter and catheter retraction. A stent according to the present invention allows positive placement of the stent near the ostium of the bifurcation. - Stents according to the invention may also be comprised of more than one self-expanding and one balloon expandable part. Any combination of these parts is deemed to be within the scope of this invention. For example, referring to
FIG. 6 , astent 10 is shown having a self-expandingpart 12 at each end of a balloonexpandable part 14. - Referring now to
FIGS. 7-10 , bifurcated stents making use of the invention are described. Generally, bifurcated stents consist of three segments or components, a main trunk and two branches. In making use of this invention, any of the three components may be made to be balloon expandable or self-expandable, as desired. For example,FIG. 7 shows an unexpanded bifurcatedstent 10 of one configuration in schematic form having atrunk 30, afirst branch 32 and asecond branch 34. As shown,trunk 30 is self-expanding, such aspart 12 in the earlier Figures, andbranches part 14 in the earlier Figures. -
FIG. 8 shows the stent ofFIG. 7 in an implanted position in abranching vessel 36. -
FIG. 9 shows another example of an unexpanded bifurcatedstent 10 of another configuration in schematic form consisting oftrunk 30 andbranches trunk 30 and branch 23 are both self-expanding andbranch 34 is balloon expandable. -
FIG. 10 shows the stent ofFIG. 9 expanded in an implanted position in abranching vessel 36. - Trunk 30 in another embodiment may be balloon expandable while the
branches - The above Examples and disclosure are intended to be illustrative and not exhaustive.
