Abstract
Abstract An expandable intraluminal stent able to resist axial compression, comprising a body portion having a generally cylindrical structure formed by a series of interconnected bars or struts, at least one of said struts being formed of two portions having overlapping free ends; and a plurality of teeth projecting on adjacent surfaces of said overlapping free ends; whereby said stent is expanded to allow said two portions of said at least one strut to overlap at said free ends, whereby said teeth on said adjacent surfaces of said overlapping free ends of said struts engage one another to retain said stent in its expanded shape.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
An expandable intraluminal stent able to resist axial compression, comprising: a body portion having a generally cylindrical structure formed by a series of interconnected structural members, at least one of said structural members being formed of two portions having overlapping free ends; and a plurality of teeth projecting on adjacent surfaces of said overlapping free ends, wherein said stent is expanded to allow said two portions of said at least one structural member to overlap at said free ends, wherein said teeth on said adjacent surfaces of said overlapping free ends of said structural member engage one another to retain said stent in its expanded shape, and wherein at least some of said interconnecting structural members form a triangular substructure having a base structural member and two angled structural members wherein said base structural member of said triangular substructure is formed of two portions having overlapping free ends.
Claim 2
Dependent Claim
148 words
An expandable intraluminal stent able to resist axial compression, comprising: a body portion having a generally cylindrical structure formed by a series of interconnected structural members, at least one of said structural members being formed of two portions having overlapping free ends; and a plurality of teeth projecting on adjacent surfaces of said overlapping free ends, wherein said stent is expanded to allow said two portions of said at least one structural member to overlap at said free ends, wherein said teeth on said adjacent surfaces of said overlapping free ends of said structural member engage one another to retain said stent in its expanded shape, and wherein at least some of said interconnecting structural members form a triangular substructure having a base structural member and two angled structural members wherein said base structural member of said triangular substructure is formed of two portions having overlapping free ends.
Claim 3
Dependent Claim
32 words
The expandable stent of claim 1 wherein said stent is capable of being carried into a vessel in a collapsed state on a balloon catheter and expanded thereby into an expanded state.
Claim 4
Dependent Claim
47 words
The expandable stent of claim 1 wherein at least some of said interconnecting structural members form a triangular substructure having a base structural member and two angled structural members, wherein said base structural member of said triangular sub-structure is formed of two portions having overlapping free ends.
Claim 5
Dependent Claim
22 words
The expandable stent of claim 3 wherein said base structural member extends longitudinally with respect to said cylindrical structure of said stent.
