Abstract
A stent includes a coil or coil-like structure comprised of joined elements which are coiled or bent and which unwind, uncoil or unbend to a more or less straightened condition on expansion of the stent.
These structures provide regions of low strain in the stent during expansion. These elements may be joined to each other or to any radially expansive members of any kind, annular serpentine members being preferred.

3 PCTIUS98/08275 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
One preferred embodiment of the invention is illustrated in Figures 1-8.
It comprises a metal tube-like structure 10 as best shown in Figures 3 and 4, such as nitinol or stainless steel, which has been etched or laser cut to the configuration shown in the plan view of Figures 1 and 2 and in a short version as shown in Figure
One preferred embodiment of the invention is illustrated in Figures 1-8.
It comprises a metal tube-like structure 10 as best shown in Figures 3 and 4, such as nitinol or stainless steel, which has been etched or laser cut to the configuration shown in the plan view of Figures 1 and 2 and in a short version as shown in Figure
4. The configuration is made up of a series of serpentine annular expandable elements or segments 12 which form loops 14 to allow for radial annular expansion.
Segments 12 may be other configurations but serpentine is preferred. Elements 12 are interconnected by pairs of elongated members 13a and 13b which are attached at one end to successive loops 14 of a segment 12 and which are joined at their other ends to adjacent pairs of elongated members 13a and 13b, as best seen in detail in Figure 2.
Members 13a and 13b are preferably of narrower gauge than members 12 and are joined together in a coiled or spiral arrangement as shown generally at 16.
Spiral 16 forms a structure about which members 13 may uncoil or unwind in a counterclockwise direction or clockwise direction to a substantially straight condition, depending on the spiral winding direction, upon radial expansion of members 12. In this embodiment spirals 16 are formed in alternate wound structures so that some unwind in one direction and some in the other direction. Of course, in any embodiment the spirals can be formed so that they all unwind in one direction, either clockwise or counterclockwise and they may have more or fewer members 13.
Also, more or less spirals may be included between the segments. The uncoiling is accompanied by a straightening action with respect to members 13 as is described in more detail in connection with Figures 4-8. It can be seen from Figures 4 through 8 that the resultant configuration in an expanded stent of this configuration is comprised of a plurality of cells, the perimeter of each of which is defmed by a pair of members or struts defined by the loop portion 14 of segment 12 and a pair of members or struts 13. The cells are joined at 16 as best seen in Figure 8. More specifically the cells are of two kinds as shown in Figure 8. A first pair of cells are A and B made up of a segment 12 and two struts 13a for cell A or 13b for cell B. A second pair of cells are C and D made up of an inward loop portion 14 of segment 12 and a strut 13a and a strut 13b for cells C and D.
When a stent of the invention, such as that shown in Figures 1-4 undergoes expansion, such as from the embodiment of Figure 4, it will appear as shown in Figure 5 in the fully expanded condition. Figure 5 shows the stent in perspective.
The unwinding action which the coil elements 16 undergo upon stent expansion is best seen in Figures 6-8 which show only the front side surface of the stent for simplicity and clarity.
As radial expansion begins (seen in Figure 6) it can be appreciated that the coil elements 16 undergo an unwinding or straightening action by a pulling force on all of the members 13. Specifically, as expansion occurs, elements 13 undergo a straightening action as can be seen in the early stages of expansion in Figure 6.
Upon further expansion (seen in Figure 7), spirals 16 undergo further unwinding, i.e., elements 13 undergo further straightening.
Finally in Figure 8, substantial full expansion provides substantially 15 straightened elements 13 which in that condition limit stent recoil and increase the resistance to compression of the stent.
Figure 9 shows a modified embodiment in which elements 13a and 13b contact segment 12 at the end of its loops 14. Also note in this embodiment that the coils 16 are all wound in the same direction.
Figure 10 shows an embodiment of the invention in which the spiral members 13 are more bent and less curvilinear but still form a coil-like configuration 16. The remainder of the configuration is similar to that of Figure 9. In Figure 10, elongate members 13 are shown prior to expansion of the stent. When the stent is expanded, members 13 unwind counter-clockwise and straighten somewhat. At full expansion members 13 straighten still further and straighten substantially so as to provide resistance to compression of the stent and low recoil. The expanded configuration displays a cell configuration similar to that seen in Figure 8.
Other embodiments are shown in subsequent Figures with different coil arrangements. For example, the embodiment of Figures 11-13 shows coiled arrangements 16 which are wound in the same direction and elements 13 attached at the end of loops 14 while some adjacent coils between segments are interconnected by members 15.
Segments 12 may be other configurations but serpentine is preferred. Elements 12 are interconnected by pairs of elongated members 13a and 13b which are attached at one end to successive loops 14 of a segment 12 and which are joined at their other ends to adjacent pairs of elongated members 13a and 13b, as best seen in detail in Figure 2.
Members 13a and 13b are preferably of narrower gauge than members 12 and are joined together in a coiled or spiral arrangement as shown generally at 16.
Spiral 16 forms a structure about which members 13 may uncoil or unwind in a counterclockwise direction or clockwise direction to a substantially straight condition, depending on the spiral winding direction, upon radial expansion of members 12. In this embodiment spirals 16 are formed in alternate wound structures so that some unwind in one direction and some in the other direction. Of course, in any embodiment the spirals can be formed so that they all unwind in one direction, either clockwise or counterclockwise and they may have more or fewer members 13.
Also, more or less spirals may be included between the segments. The uncoiling is accompanied by a straightening action with respect to members 13 as is described in more detail in connection with Figures 4-8. It can be seen from Figures 4 through 8 that the resultant configuration in an expanded stent of this configuration is comprised of a plurality of cells, the perimeter of each of which is defmed by a pair of members or struts defined by the loop portion 14 of segment 12 and a pair of members or struts 13. The cells are joined at 16 as best seen in Figure 8. More specifically the cells are of two kinds as shown in Figure 8. A first pair of cells are A and B made up of a segment 12 and two struts 13a for cell A or 13b for cell B. A second pair of cells are C and D made up of an inward loop portion 14 of segment 12 and a strut 13a and a strut 13b for cells C and D.
When a stent of the invention, such as that shown in Figures 1-4 undergoes expansion, such as from the embodiment of Figure 4, it will appear as shown in Figure 5 in the fully expanded condition. Figure 5 shows the stent in perspective.
The unwinding action which the coil elements 16 undergo upon stent expansion is best seen in Figures 6-8 which show only the front side surface of the stent for simplicity and clarity.
As radial expansion begins (seen in Figure 6) it can be appreciated that the coil elements 16 undergo an unwinding or straightening action by a pulling force on all of the members 13. Specifically, as expansion occurs, elements 13 undergo a straightening action as can be seen in the early stages of expansion in Figure 6.
Upon further expansion (seen in Figure 7), spirals 16 undergo further unwinding, i.e., elements 13 undergo further straightening.
Finally in Figure 8, substantial full expansion provides substantially 15 straightened elements 13 which in that condition limit stent recoil and increase the resistance to compression of the stent.
Figure 9 shows a modified embodiment in which elements 13a and 13b contact segment 12 at the end of its loops 14. Also note in this embodiment that the coils 16 are all wound in the same direction.
Figure 10 shows an embodiment of the invention in which the spiral members 13 are more bent and less curvilinear but still form a coil-like configuration 16. The remainder of the configuration is similar to that of Figure 9. In Figure 10, elongate members 13 are shown prior to expansion of the stent. When the stent is expanded, members 13 unwind counter-clockwise and straighten somewhat. At full expansion members 13 straighten still further and straighten substantially so as to provide resistance to compression of the stent and low recoil. The expanded configuration displays a cell configuration similar to that seen in Figure 8.
Other embodiments are shown in subsequent Figures with different coil arrangements. For example, the embodiment of Figures 11-13 shows coiled arrangements 16 which are wound in the same direction and elements 13 attached at the end of loops 14 while some adjacent coils between segments are interconnected by members 15.

Figure 14 shows some elements 13 in a spiral 16 contacting the end of loops 14 and some contacting segment 12 proper. Also, some adjacent coils are interconnected by members 17.
Figure 15 shows a flattened or elongated coil arrangement 16 and elements 12 are angled with respect to the longitudinal axis of the stent. In previous embodiments, these elements or segments have been arranged parallel to the axis or horizontal. Elongated spirals as in Figure 13 and coils of previous Figures may be mixed together. (Not shown).
In the embodiments already discussed, annular expandable segments such as segments 12 are interspersed with coil arrangements 16. However, as can be seen in Figure 16, at least a substantial portion or all of the stent body can be merely comprised of spiral arrangements 16 connected to each other. Actually, all of the body may consist of spirals. In this embodiment, the elements 13 interconnect between spirals over substantially the entire body of the stent. Optionally, the ends-may include segments 12 as shown.
The embodiment shown in Figure 17 shows segments 12 alternately angled in opposite directions and with legs thereof of different length and elements 13 contacting the segments at different locations, i.e., as at the loop portion 14 and at the segment portion proper.
Figures 18-28 demonstrate examples of what is meant by the terms coil, spiral and coil-like herein. Of course, additional members may be included in the coils.
Figure 29 shows segments 12 in a configuration other than the annular serpentine configuration of previous Figures.
Figure 30 shows alternate segments 12 in serpentine annular configuration interconnected by double rows of interconnected coil configurations 16.
Figure 31 is included to demonstrate that coils 16 may be included on the ends of a stent 10.
