No. 6,117,165.
The present invention is directed to an expandable stents that have relatively uniform stent-to-vessel ratios when expanded and other desirable properties, as well as methods for making these stents. The stents of the present invention comprise a generally cylindrically shaped main body having a plurality of expandable helical segments. The main body is comprised of a plurality of cylindrical main body elements that are joined together by the helical segments. The cylindrical elements have cylindrical axes that are collinear with the cylindrical axis of the main body. The cylindrical elements are formed from a plurality of circumferential elements that are joined together by the expandable helical segments. In some embodiments, the stent may comprise endzones that straddle the main body.
The main body 11, shown in FIGS. 1 and 2, may be formed in numerous ways. For example, the body 11 may contain two or more first helical segment 30 and 40 that are generally parallel to each other. In some embodiments they may be opposite each other by 180°. In general, the first helical segments 30 and 40 will be spaced equidistant along the circumference 110 of the main body 11. The first helical segments 30 and 40 are joined by a plurality of circumferential segments 50 to form a plurality of main body cylindrical elements 100, which may be only generally cylindrically shaped. In one embodiment, the circumferential segments 50 make up a majority of the circumference 110 of each cylindrical element 100. In addition to joining the circumferential elements 50 to form cylindrical elements 100, the helical segments 30 and 40 connect each cylindrical element 100 to an adjacent cylindrical element 100 to form the main body 11.
As is shown in FIG. 3, the body of the stent 11 may comprise a plurality of main body cylindrical elements 100 formed from first circumferential segments 50 that are joined with second circumferential segments 60. The second circumferential segments 60 of each cylindrical element 100 may be joined with second circumferential segments 60 of adjacent cylindrical elements 100 to form a plurality of first helical segments 30 and 40 in the main body 11. (See FIG. 2). Each first circumferential segment 50 may have a circumferential dimension 55 and each second circumferential segments 60 may have a circumferential dimension 66. (See FIG. 3) In some embodiments, it may be desirable for the circumferential dimension 55 of the first expandable element 50 to be larger than the circumferential dimension 66 of the second expandable element 60.
In the embodiment shown in FIGS. 1-5, the first circumferential elements 50 comprise linear portions 320 and curved portions 328 that join the linear portions 320 together to form a repeating pattern. In some, but not all, embodiments, the linear portion 320 may be parallel to the cylindrical axis of the stent. The first circumferential segment 50 has an amplitude 350 and a period 380. In one embodiment the amplitude may range from 0.5 mm to 2.0 mm and the period may range from 0.5 mm to 2.0 mm. In some embodiments, the amplitude is less than the period. Other amplitudes and periods may be used depending on the overall stent design and performance constraints.
The second circumferential element 60, which may be joined together in a helical pattern to form one or more helical segments 30 or 40, may also take numerous forms, in addition to the form shown in FIG. 6. In the embodiment shown in FIG. 6, the second circumferential element 60 comprises linear portions 412 and curved portions 414 having a filament width 407, and resembles generally an S-shaped structure. In addition, the second element circumferential segment 60 may have an angled portion 417 attached to the linear portion 412 at an end opposite that of the curved portion 414. The angled portion may be oriented to form an angle α relative to the cylindrical axis of the stent 5 in the range of 0-45 degrees. In at least one embodiment, the preferable angle α is about 10 degrees. In some embodiments, the linear portions 412 of the second circumferential element 60 lies at an angle Ω relative to the cylindrical axis of the stent, wherein Ω preferably ranges from 0 to 45 degrees. When viewed in a planar fashion as in FIG. 2, the linear portions 412 may, in some embodiments, form an angle Ω, relative to the cylindrical axis of the stent. In some embodiments, Ω may be approximately equal to the helical angle of the first helical segments 30 and 40. In one embodiment, the second circumferential elements 60 may have an amplitude 300 (see FIGS. 3, 4, and 6) ranging from 0.5 mm to 2.0 mm and a period ranging from 0.5 mm to 2.0 mm. Other ranges may be used depending on the particular stent size and design being employed. In one embodiment, the preferred period is about 0.82 mm and the preferred length of the linear portion 412 is about 0.5 mm and the amplitude 300 is about 0.38 mm. The amplitude of the second circumferential element 60 may be greater than, equal to, or less than the amplitude of the first circumferential element 50. In one embodiment, the circumferential contributions of the first circumferential elements 50 to the overall circumference of the main body 11 is greater than the circumferential contribution of the second circumferential element 60, in terms of either circumferential length or circumferential cylindrical surface area. In one embodiment, the stent may have an overall outer surface area of about 0.029 square inches.
As is shown in FIG. 7, the stent may have a main body 11 comprised of two or more first helical segments 30 and 40, as well as two or more second helical segments 200 and 210. The first and second helical segments 30, 40 and 200, 210, respectively, are joined together to form a generally cylindrically shaped body 11. In some, but not all embodiments, the first and second helical segments may share a common connecting element 250. In some embodiments, the common connecting element 250 may be H-shaped and the two generally parallel linear portions of the H-shaped connecting segment 250 may form an angle δ relative to the axis 5. (See FIG. 6). δ may, in one embodiment, be about 14 degrees. As is shown in FIG. 7, the first helical segments 30 and 40 and second helical segments 200 and 210 may have different pitches, i.e. number of spirals per unit length, which results in the first and second helical segments as having different helical angles (θ and β, respectively) i.e. the angle of the helical segment relative to the cylindrical axis 5 of the stent. In one embodiment, the second helical segments 200 and 210 have a pitch approximately twice that of the first helical segments. In one embodiment θ may vary from 0 to 45 degrees and is preferably about 40 degrees and β is preferably about twice θ. In other embodiments the angle θ may range from 0 to 90 degrees to the circumference 110 of each cylindrical element 100.
Some, but not all embodiments, of the present invention may employ endzones 10 and 20. (See FIGS. 1, 2, and 11). Stents that employ endzones will generally have two endzone regions straddling a central zone in the middle of the stent. The stents may also have a transition region between the endzone and the central zone. The transition region serves to help smoothly transition between the expanded middle region and an portions of the end of the stent that remain unexpanded after the stent is implanted. The size and characteristics of the transition region are a function of the material and geometry of the stent. For example, the transition range properties vary as a function of, among other things, the helical angle of the first helical segments, the number of curved segments located in the endzones, and the angle ε of the linear portions of the segments forming the endzones. (See e.g. FIG. 8).
In the embodiment shown in FIGS. 1, 7, 8, and 9, which is exemplary only, the linear segments 28 in the endzone 10, are oriented at an angle ε relative to the cylindrical axis of the stent. The angle ε may range from 0 to 45 degrees and in one embodiment is preferably about 10 degrees. The segments of the endzone may have a filament width 13 of between 0.002 and 0.007 inches. In one embodiment, the repeating pattern of the endzone has a period 2 of about 0.027 inches and an amplitude 21 of about 0.043 inches. Other values may be used. As is shown in FIG. 1, the struts 15, which are but one way to attach the endzones 10 and 20 to the main body 11, may, in one embodiment have a width of between 0.002 inches and 0.08 inches and preferably the width does not exceed the wall thickness, which typically—but not necessarily ranges from about 0.002 to 0.008 inches.
While endzones 10 and 20 may be used to provide square edge, not all stents according to the present invention require endzones. FIGS. 12-15 depict an endzoneless stent. Like the stent shown in FIGS. 1-9, the stent of FIGS. 12-15, comprises a plurality of adjacent cylindrical elements 100. The cylindrical elements 100 are formed from a plurality of first circumferential elements 50′ and second circumferential elements 60. The first circumferential elements 50′ of the stent in FIGS. 12-15 are substantially identical to the second circumferential element 60 except that they are rotated to have a different orientation. The circumferential elements may be generally S-shaped having a linear portion 412, a curved portion 414 having a radius R, and an angled portion 417. R may vary widely depending on overall stent characteristics and in one embodiment varies between 0.001 and 0.02 inches and is preferably about 0.0083 inches. The angled portion 417 is spaced a distance 499 from the linear portion. In one particular embodiment, the distance 499 may vary from 0.002 to 0.020 inches and is preferably about 0.007 inches. The filament width 407 of the elements may, in one embodiment, be about 0.13 mm.
The stent of the present invention may be manufactured in numerous ways. The stent may be formed from a metallic tube by removing various portions of the tube's wall to form the patterns described herein. The resulting stent will thus be formed from a single contiguous piece of material, eliminating the need for connecting various segments together. Material from the tube wall may be removed using various techniques including laser (YAG laser for example), electrical discharge, chemical etching, metal cutting, a combination of these techniques, or other well known techniques. See e.g. U.S. Pat. No. 5,879,381 to Moriuchi et al. and U.S. Pat. No. 6,117,165 to Becker, which are hereby incorporated in their entirety by reference. Forming stents in this manner allows for creation of a substantially stress-free structure where the helical segments are integral with the circumferential elements. In one embodiment, the tube from which the stent is formed may have an internal diameter of about 3.0 mm, a wall thickness of about 1.0 mm and a length of about 30 mm. Tubes having other dimensions may be used. In particular, the length may be adapted to that of the diseased part of the lumen in which the stent is to be placed. This may avoid using separate stents to cover the total diseased area.
