In a second embodiment, a first sheet is formed into a member having a first leg and half of a stem, a second sheet is formed into a second member having a second leg and half of a stem, and the two stem halves are combined to form the bifurcated stent. In a third embodiment, the stent comprises two sections that are serially inserted and assembled within the vessel at the site of the bifurcation to be treated.
Description
BIFURCATED STENT AND METHOD OF MAKING SAME VI)*» fl\5»¾» J ott WJ\?X> For the Applicant, Eitan, Pearl, Latzer & Cohen-Zedek Advocates, Patent Attorneys & Notaries P-1245-IL1 . .
Field of the Invention The present invention relates to stents, and more oart icularly to bifurcated stents and methods of making bifurcated stents for insertion within a branching vessel.
Background of the Invention Stents are well known in the art. They are typically formed of a cylindrical metal mesh which can expand when pressure is internally applied. Alternatively, they can be formed of wire wrapped into a cylindrical shape or sheets of material formed into a cylindrical shape.
Stents are devices which are usually implanted within bodily conduits including the vascular system to reinforce collapsing, arcially occluded, weakened, or abnormally dilated sections of : e blood vessel. Stents also have been successfully implanted r. or'ner areas, e.g., the urinary tract or the bile duct to reinforce such bodily conduits.
U.S. Patent No. 4,994,071 (MacGregor) discloses an expandable, bifurcating stent having a main cylindrical lattice rorr.ed from interconnected, flexible. Two additional cylindrical lattices, having smaller diameters than the main lattice, are similarly constructed. The main lattice includes a flexible wire interconnecting the main lattice to o¾e of the additional lattices. A second flexible wire interconnects the main lattice backbones that extend axially along the length of the main lattice and along each of the additional lattices. One disadvantage of this bifurcating stent is the complex nature of che interconnection of the flexible wires forming the backbones - wich che loop structure of each lattice.
Summary of the Invention The present invention solves these and other disadvantages of the prior art by providing bifurcated stents and methods of fabricating and deploying bifurcated stents having a stem portion and two leg portions. engages the material defining the branch aperture so as to secure the second leg in the desired position.

Detailed Description In the embodiment illustrated in FIG. 1, the bifurcation scent 5 comprises a first leg 10, a second leg 15, and a stem 20. FIG. 2 shows a first sheet 25 which is used to form first leg 10, a second sheet 30 which is used to form second leg 15, and a third sheet 35 which is used to form stem 20. The first sheet 25 and second sheet 30 are substantially Jflat and are si*zed to a predetermined length and width. For many applications, the first dimensions so as to produce legs 10 and 15 that are substantially the same size, however, the legs 10 and 15, and the sheets 25 and 30 used to produce them, may be of varying sizes as specific applications dictate. The stents of this invention may be sized so that when assembled they are their final size, however, in a preferred embodiment the stents are expandable and sized and adapted to assume their final dimensions upon expansion. The stent sheets 70 and 75 may be patterned or etched with perforations forming a variety of patterns as specific applications dictate to achieve the expandable features required as previously discussed. The third sheet 35 is sized so that when it is rolled into a tube its internal cross -section can be made to accommodate the cross - sectional external diameters of first- leg 10 and second leg 15. First sheet 25 has a first edge 26, a second edge 27, a third edge 28, and a fourth edge 29.
Second sheet 30 has a first edge 31, a second edge 32, a third edge 33, and a fourth edge 34. Third sheet 35 has a first edge 36, a second edge 37, a third edge 38, and a fourth edge 39.
After the sheet metal has been cut to form sheets 25, 30, and 35, it is deformed and rolled so as to cause two opposite edges to meet and create a cylinder. In the example shown in FIGs. 2 and 3, edge 27 is joined to edge 29 via weld run 14 to form first leg 10. Edge 32 is joined to edge 34 via weld run 19 to form second leg 15. Edge 37 is joined to edge 39 via weld run 29* to form stem 20. The edges may be joined in a wide variety of ways well ow e, e.g., screwing, crimping, soldering, however, in a preferred embodiment welding is utilized. In an especially preferred embodiment, spot welding is utilized. As shown in FIG. 3, first leg 10 has a proximal end 11, a distal end 12, and defines a longitudinal bore 13. Second leg 15 has a proximal end 16, a distal end 17, and defines a longitudinal bore 18. The stem 20 has a proximal end 26, a distal end 27, and defines a longitudinal bore 28. FIG. 4 shows the first leg 10, second leg 15, and stem 20 just prior to assembly. To form the bifurcated stent 5, the proximal end 11 of first leg 10 and the proximal end 16 of second leg 15 are joined to the distal end 27 of the stem portion 20 so that the longitudinal bores 13, 18, and 28 are in communication with each other. FIG. 5 is an end view and FIG. 6 is a side view of the assembled apparatus.
FIG. 11 shows a second embodiment of a bifurcation stent manufactured in accordance with this invention. The stent 50 is provided with a first leg 55 and a second leg 60 attached to a seem portion 65. The bifurcation stent 50 is formed from a first sheet 70 and a second sheet 75 as shown in FIG. 7. The stent sheets 70 and 75 may be patterned or etched with perforations forming a variety of patterns as specific applications dictate to achieve the expandable features required as previously discussed. The sheets 70 and 75 are substantially flat and have a predetermined length and width. Firs^ sheet 70 has a* first edge 7i, a second edge 72, a third edge 73 and a fourth edge 74. The , , edge 78, and a fourth edge 79. To form the legs of the stent a portion of edge 72 is rolled towards a portion of edge 74 and a portion of edge 77 is rolled towards a portion of edge 79.
Demarcation points 80, 81, 82, and 83 are selected on sheets 70 and 75 as shown in FIG. 8. These demarcation points 80, 81, 82, and 83 are selected to meet the requirement of specific applications and "may be adjusted depending upon the length required for legs 55 and 60 and the length required for stem 65. Demarcation points 80 and 81 that are equidistant from edges 73 and 71 and demarcation points 82 and 83 that are equidistant from edges 76 and 78 will result in a stent in which the legs 55 and 60 have a length that is substantially equal to stem portion 65. If the demarcation points are selected to be closer to edges 73 and 78 than to edges 71 and 76 the stem will have a length that is greater than the length of each of the legs. If the demarcation points are selected to be closer to edges 71 and 76 than to edges 73 and 78, each of the legs 60 and 65 will have a length that is greater than the length of the stem 65. In a preferred embodiment, however, the demarcation points 80, 81, 82, and 83, are selected so that proximal edges 72'', 74'', 77'', and 79'' are about 1/3 the length of edges 72, 74, 77, and 79. As shown in FIG. 8, demarcation point 80 divides edge 72 at approximately its midpoint into a distal edge 72' and a proximal edge 72''. Demarcation point 81 divides edge 74 at a proximately its midpoint into a distal edge 74' and a proximal edge 74''. midpoint into a distal edge 77' and a proximal edge 77' ' and demarcation point 83 divides edge 79 at approximately its midpoint into a distal edge 79' and a proximal edge 79''.
To form the stent, edge 72' is connected to edge 74' via weld run 90 to form first member 95 having a first leg portion 55 and a first stem half 65' as shown in FIG. 9. Edge 77' is connected to edge 79' via weld run 91 to form second member 100 having a second leg portion 60 and a second stem half 65''·. As previously discussed, the edges may be connected in a variety of ways well known to those skilled in the art. FIG. 10 shows the first member 95 and the second member 100 shown in FIG. 9. in alignment just prior to assembly. To produce the bifurcated scent 50 shown in FIGS. 11 and 12, edge 72'' is connected to edge 79'' via weld run 92 and edge 74'' is connected to edge 77'' via weld run 93 so that first stem half 65' and second stem half 65'' form stem 65. FIG. 12 is a cross - sectional end view of the stent shown in FIG. 11.

A third embodiment of this invention comprises two portions which are deployed serially in two steps and assembled within the patient to form a bifurcated stent. £IG. 13 shows stem and first leg portion 110 provided with a longitudinal bore 131 and having a prox ma en e n ng a s em port on 1 an a sta en 120 defining a first leg portion 130. Second leg portion 140 is provided with a longitudinal bore 132 and has a proximal end 145 and a distal end 150. Stem and firs leg portion 110 and second leg portion 140 may be sized and patterned or etched as previously discussed. A branch aperture 135 is disposed between the proximal end 115 and the distal end 120 of stem and first leg portion 110. The branch aperture 135 is sized to receive second leg portion 140 and is adapted to engage and secure the second leg portion 140 when it has been expanded within the branch aperture 135. Second leg portion 140 is sized and adapted to engage and be secured into branch aperture 135 upon expansion. FIGS. 14 to 21 show how the bifurcated stent is assembled within a bifurcated lumen. As shown in FIGS. 14 to 21, the area to be treated is a bifurcated lumen having a first or trunk lumen 190 and a second or branch lumen 195. As shown in FIG. 14, a first gu-de wire 155 is introduced into the trunk lumen 190 and a second guide wire 156 is introduced into the branch lumen 195. As shown in FIG. 15, a balloon expandable stem and first leg portion 110 is disposed on the tip of a first balloon catheter 170 so that the balloon 175 is disposed within longitudinal bore 131. A second balloon catheter 171 is then introduced into longitudinal bore 131 of stem and first leg portion 110 and is advanced so that the balloon 176 is disposed within aperture 135. First catheter 170 is mounted on firs^ guide wire 155 and second catheter 171 is mounted on second guide wire 156. As shown in . , o the area to be treated so that first leg portion 130 is disposed within trunk lumen 190 and branch aperture 135 communicates with branch lumen 195. Guide wire 156 facilitates the orientation of the branch aperture 135 with the branch lumen 195. The size of the conventional catheters and balloons is not to scale and details well known to those skilled in the art have been omitted for" clarity. Balloon 175 is inflated which causes the stem and first leg portion 110 to expand, as shown in FIG. 17, to secure it in the desired position. After expansion, the external wall of stem and first leg portion 110 would contact the interior walls of trunk lumen 190, however, a gap has been intentionally left for clarity. The balloon 175 on first catheter 170 is left inflated and the balloon 176 on second cathe-ter 171 is then inflated to enlarge the branch aperture 135 as shown in FIG. 18. As the branch aperture 135 is enlarged a portion of the stent defining the branch aperture 135 is pushed outward to form a branch securing lip 180.
Balloons 175 and 176 are deflated, second catheter 171 is withdrawn, and second guide wire 156 is left in place in the branch lumen 195. Second leg portion 140 is then applied to second catheter 171 so that first balloon 176 is disposed in longitudinal bore 132 and second catheter 171 is then applied to second guide wire 156. Second leg portion 140 is then guided to, and introduced into, the longitudinal jDore 131 of thi stem and first leg portion 110 and is advanced and passed through branch aper ure e secon eg port on 140 protrudes into the branch lumen 195 and the proximal end 145 communicates with longitudinal bore 131, as shown in FIG. 19. The balloon 176 on second catheter 171 is partially inflated and the balloon 175 on first catheter 170 is then partially inflated to a pressure substantially equal to the pressure in balloon 176. Both balloons 175 and 176 are then simultaneously inflated to substantiall equal pressures. As shown in FIG. 20, inflation of the balloon 176 on second catheter 171 causes second leg member 140 to expand so that its external walls engage and are secured to the area surrounding aperture 135. Inflation of the balloon 175 on the first catheter 170 prevents stem and first leg portion 110 from collapsing when balloon 176 is inflated. After expansion, the external walls of second leg 140 would contact the inner wall of lumen 195, however, a gap has been intentionally left for clarity. The balloons 175 and 176 are deflated, catheters 170 and 171 and guide wires 155 and 156 are withdrawn, ar.c the assembled bifurcated stent 160 is left in place as shown in FIG . 21.
