Abstract

Abstract Embodiments of multiple interconnected stents each include a stent having a plurality of rows of slots with spaces between the slots being staggered in adjacent rows. In each embodiment, a plurality of stents are interconnected together with a connector. In one embodiment, the connector consists of a single flexible bar. In a second embodiment, the connector consists of a plurality of U-shaped members fused together. In a third embodiment, the connector consists of a plurality of slots orthogonal to the stent slots. In a fourth embodiment, a multiplicity of stents are interconnected together by flexible bars that are vertically staggered with respect to one another. In a fifth embodiment, adjacent stents are interconnected by flexible connectors resembling the letter "H". In a sixth embodiment, adjacent stents are interconnected by a plurality of vertically spaced horizontal bars. In a seventh, eighth and ninth embodiment, adjacent stents are interconnected by a plurality of flexible connectors resembling the letter "W", "V" and "U", respectively. The stents are prepared by coating a metal tube with a polymer, removing a predetermined portion of the polymer and removing the exposed metal by etching or electrolysis.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 116 words
A multiple linear segment stent comprising: a) at least first and second linear segments, each linear segment formed from a generally rectangular body formed into a tube, said body having top and bottom edges fused together to form said tube, said body having a plurality of parallel rows of slots, each row having a plurality of longitudinal slots separated from one another by spaces, said spaces being laterally staggered in adjacent rows; b) said linear segments being interconnected together by flexible interconnection elements attached at juxtaposed positions on adjacent linear segments for use in traversing a blood vessel, said interconnection elements becoming rigid and increasing in length upon expansion of the stent in the blood vessel.
Claim 2
Dependent Claim 116 words
A multiple linear segment stent comprising: a) at least first and second linear segments, each linear segment formed from a generally rectangular body formed into a tube, said body having top and bottom edges fused together to form said tube, said body having a plurality of parallel rows of slots, each row having a plurality of longitudinal slots separated from one another by spaces, said spaces being laterally staggered in adjacent rows; b) said linear segments being interconnected together by flexible interconnection elements attached at juxtaposed positions on adjacent linear segments for use in traversing a blood vessel, said interconnection elements becoming rigid and increasing in length upon expansion of the stent in the blood vessel.
Claim 3
Dependent Claim 30 words
The multiple linear segment stent of claim 1, wherein each said interconnection element comprises at least one U-shaped member on said first linear segment attached to said second liner segment.
Claim 4
Dependent Claim 23 words
The multiple linear segment stent of claim 4, wherein the first and second linear segments are connected by a plurality of U-shaped members.
Claim 5
Dependent Claim 16 words
The multiple stent of claim 1, wherein said stents are formed in a single rectangular body.
Claim 6
Dependent Claim 28 words
The multiple stent of claim 4, wherein said interconnection means comprises a plurality of interconnection slots in said single rectangular body orthogonal to said slots of said stents.
Claim 7
Dependent Claim 13 words
The multiple stent of claim 1, wherein said interconnection means is "H" shaped.
Claim 8
Dependent Claim 14 words
The multiple stent of claim 6, including a plurality of "H" shaped interconnection means.
Claim 9
Dependent Claim 13 words
The multiple stent of claim 1, wherein said interconnection means is "W" shaped.
Claim 10
Dependent Claim 15 words
The multiple stent of claim 1, wherein said stents are coated with a polymeric coating.
Claim 11
Dependent Claim 15 words
The multiple stent of claim 1, wherein said stents are coated with a biological coating.
Claim 12
Dependent Claim 13 words
The multiple stent of claim 1, wherein said interconnection means is "V" shaped.
Claim 13
Dependent Claim 19 words
The multiple stent according to claim 1 wherein there are at least three stents interconnected by flexible interconnection means.
