Definitions
- This invention relates to stents of improved configuration.
- Stents are radially expandable endoprosthesis which are typically intravascular implants capable of being implanted transluminally and enlarged radially after being introduced percutaneously. They have also been implanted in urinary tracts and bile ducts. They are used to reinforce body vessels and to prevent restenosis following angioplasty in the vascular system. They may be self-expanding or expanded by an internal radial force, such as when mounted on a balloon.
- stents have been generally tubular but have been composed of many configurations and have been made of many materials, including metals and plastic. Ordinary metals such as stainless steel have been used as have shape memory metals such as Nitinol and the like. Stents have also been made of biodegradable plastic materials. Such stents have been formed from wire, tube stock, etc.
- This invention provides new configurations of the cells making up stents which may be adapted to all of the various types of prior art stents described above and/or known previously in the art. There are numerous advantages to the new configurations.
- the configurations of the invention limit recoil and add resistance to compression for an expanded stent, among other things.
- Other configurations than cylindrical are contemplated, e.g., square, triangular octagonal, etc.
- the stents of this invention are longitudinally flexible and expandable.

- FIG. 1 A preferred embodiment of a generally cylindrical stent 10 according to the invention is illustrated in Figures 1-4. It comprises a metal tube as shown in Figures 2 and 4, such as nitinol or stainless steel preferably, which has been etched or preferably laser cut to the configuration shown in the flat plan view of Figure 1.
- Figure 3 An enlarged detail of Figure 1 is shown in Figure 3.
- the configuration is made up of a series of curvilinear expansion cell elements generally indicated at 12 (see darkened example in Figure 3 for clarity) having relatively wide end portions 14 joined by relatively narrow center portions 16.
- Cells 12 are arranged longitudinally as shown in Figure 1 end to end with respect to the longitudinal axis of the stent 10 and in substantially parallel rows as also shown in Figure 1.
- a plurality of longitudinally extending elongate support members 18 are included, one each being disposed between adjacent rows of cells 12.
- a plurality of circumferentially extending support members 19, preferably substantially normal to support members 18 are also positioned between the rows of cells 12 to intersect portions of the support members 18 and to interconnect them to the narrow center portions 16 of cells 12.
- cells 12 may also be arranged in a staggered arrangement.
- Figures lb and lc demonstrate different arrangements and interconnections for cells 12.
- expansion cells 24 best seen in the detail of Figure 6 and indicated by darkened portion, have relatively wide end portions 26, best seen in Figure 6, and narrow center portions 28 and are arranged end to end in longitudinal rows as described with respect to the first embodiment. Adjacent end portions 26 are interconnected by pairs of longitudinal support members in the form of segments 30 which have curved end portions 32. Circumferential extending segments 34 extend between rows of cells 24 to interconnect the narrow center portions 28.
- expansion cells 24 Upon radial expansion of the stent, as on a balloon 20 for example, its configuration changes by deformation force in the directions shown by the arrows in Figure 6 to that configuration shown in Figure 7.
- the elements indicated in Figure 7 are identified by the same numbers indicated for similar elements in Figures 5 and 6.
- Figures 20 and 21 show a configuration somewhat similar to that of Figures 5-7 but without interconnecting elements 28.
- expansion cells 42 (example darkened for clarity) have relatively wide end portions 44 and narrow center portions 46.
- the end portions include inwardly extending loop portions 48.
- Cells 42 are arranged end to end in longitudinal rows as in the preceding embodiments.
- Adjacent end portions 44 are interconnected by pairs of longitudinal support member segments 50 which have curved end portions 52.
- Circumferentially extending segments 54 extend between rows of cells 42 to interconnect the narrow center portions 46 of the cells.
- Figure 8a shows a variation in shape for cells 42. Upon radial expansion of the stent upon a balloon 20, the configuration changes to that shown in Figure 10. The arrows show the direction of force of deformation upon expansion.
- expansion cells 62 (example darkened for clarity) have relatively wide end portions 64 having a slight inward bend 65 to them and narrow center portions 66.
- Cells 62 are arranged end to end in longitudinal rows as in the preceding embodiments.
- Adjacent end portions 64 are interconnected by pairs of longitudinal support member segments 68 which have curved end portions 70.
- Circumferentially extending segments 72 extend between rows of cells 62 to interconnect the narrow center portions 66 of the cells.

- Cells 82 are arranged end to end in longitudinal rows as in the preceding embodiments.
- Adjacent end portions 84 are interconnected by pairs of longitudinal support member segments 88 which have curved end portions 90.
- Circumferentially extending segments 92 extend between rows of cells 82 to interconnect the narrow center portions 86 of the cells.
- Circumferentially extending segments 81 interconnect pairs of support member segments 88.
- FIG. 18 shows yet another embodiment of a stent configuration 100 .
- this embodiment is similar to that of Figures 11-12 except that the circumferentially extending segments 101 are arranged differently than those identified in Figures 11-12 as 72.
- the circumferentially extending members 101 extend between the adjacent ends of adjacent cells 103 (examples darkened for clarity) to interconnect the top of one end to the bottom of the adjacent end and the members 101 have a slight curve or bend 105 in their length.
- the other members are all similarly numbered as in the preceding Figures.
- Figure 22 shows yet another embodiment of a stent comprised of cells
- the cells have interconnecting circumferential extending members 122.
- the cells have common sides or end members 124 and are arranged in groups to form bands 126 which are interconnected by joined cells 128.
