Description

BALLOON EXPANDABLE STENT WITH A SELF-EXPANDING PORTION
Field of the Invention
The present invention relates to a new type of stent for transluminal implantation and in particular new vascular stents.
Background of the Invention
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.
Summary of the Invention 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.

Figure 2 is a schematic showing of a stent similar to that of Figure 1 on a delivery catheter;
Figure 3 is a schematic showing of the delivery system of Figure 2 with the stent released for implantation;

Figure 6 is a showing of another embodiment of a stent according to the invention, and Figures 7-10 are schematic showings of bifurcated stents making use of the invention.
Detailed Description of the Preferred Embodiments
Figure 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-expanding part 12 joined at one end in juxtaposition to the proximal end of a balloon expandable 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-expanding part 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 of part 12 aids in placement of the stent during release, following which a balloon or the like may be used to expand part 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 in Figures 2 and 3 which show a stent 10 similar to that of Figure 1 on a delivery catheter. Figure 2 shows the stent having the two parts 12 and 14, respectively. Part 12 is the self-expanding part while part 14 requires a separate force for expansion such as a balloon 16 of a delivery catheter generally indicated at 18 inside the stent. In Figure 2, the stent is shown prior to release or deployment, the self-expanding part is enclosed by a retractable sheath 20. In Figure 3, the sheath has been retracted, allowing self-expanding part 12 to flare- outwardly. Subsequently, balloon 16 may be used in the known manner to expand part 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 figures 4 and 5 at 10. Figure 4 shows the stent having a proximal end part 12 which is self-expanding while the remainder of the stent body 14 is balloon expandable by balloon 16 on catheter 18. In Figure 4, the retractable sheath has been removed allowing the self- expanding part to expand at the ostium 22 in a vessel 24 branching off of a main vessel such as aorta 26, helping to more accurately place the stent. Figure 5 shows the stent after expansion of part 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 Figure 6, a stent 10 is shown having a self-expanding part 12 at each end of a balloon expandable part 14. Referring now to Figures 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, Figure 7 shows an unexpanded bifurcated stent 10 of one configuration in schematic form having a trunk 30, a first branch 32 and a second branch 34. As shown, trunk 30 is self-expanding, such as part 12 in the earlier Figures, and branches 32 and 34 are balloon expandable, such as part 14 in the earlier Figures.
Figure 8 shows the stent of Figure 7 in an implanted position in a branching vessel 36.
Figure 9 shows another example of an unexpanded bifurcated stent 10 of another configuration in schematic form consisting of trunk 30 and branches 32 and 34. In this case, trunk 30 and branch 23 are both self-expanding and branch 34 is balloon expandable.
Figure 10 shows the stent of Figure 9 expanded in an implanted position in a branching vessel 36. Trunk 30 in another embodiment may be balloon expandable while the branches 32 and 34 may be self-expandable.
