Abstract
Abstract A prosthetic stent with a tubular wall having local inwardly or outwardly formed elevations. Stents having such elevations have a higher mechanical stability if bend according to the curvature of the body vessels to be supported or repaired. Also a method for manufacturing a stent with such elevations is described.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
41 words
1 . A stent for use in a body passageway comprising a flexible self-expanding braided tubular wall comprising helically wound wires and having proximal and distal ends, wherein the tubular wall has at least a local inwardly and/or outwardly formed elevation.
Claim 2
Dependent Claim
41 words
1 . A stent for use in a body passageway comprising a flexible self-expanding braided tubular wall comprising helically wound wires and having proximal and distal ends, wherein the tubular wall has at least a local inwardly and/or outwardly formed elevation.
Claim 3
Dependent Claim
17 words
2 . The stent of claim 1 comprising multiple local elevations distributed regularly over the tubular wall.
Claim 4
Dependent Claim
20 words
3 . The stent of claim 1 comprising multiple local elevations distributed more densely at the proximal and distal ends.
Claim 5
Dependent Claim
17 words
4 . The stent of claim 1 wherein the at least one local elevation is formed outwardly.
Claim 6
Dependent Claim
18 words
5 . The stent of claim 1 wherein the at least one local elevation has an elongated shape.
Claim 7
Dependent Claim
18 words
6 . The stent of claim 5 wherein the at least one elevation has an arched cross-sectional shape.
Claim 8
Dependent Claim
28 words
7 . The stent of claim 6 wherein the at least one elevation has a height of approximately one to two times of a diameter of the wires.
Claim 9
Dependent Claim
20 words
8 . The stent of claim 5 wherein the at least one elevation is formed helically on the tubular wall.
Claim 10
Dependent Claim
24 words
9 . The stent of claim 8 wherein the at least one helical elevation has a different pitch than the wires of the braid.
Claim 11
Dependent Claim
20 words
10 . The stent of claim 5 wherein the at least one elevation is formed annularly on the tubular wall.
Claim 12
Dependent Claim
23 words
11 . The stent of claim 5 wherein the at least one elevation is formed in an axial direction on the tubular wall.
Claim 13
Dependent Claim
85 words
12 . A method for manufacturing a stent comprising: (a) providing an elongated mandrel having an outer diameter and at least one local outwardly bound elevation; (b) forming an elongated metallic tubular braid having proximal and distal ends, the braid having an inner diameter commensurate with the outer diameter of the mandrel; (c) engaging the tubular braid over the mandrel; (d) heating the tubular braid while it is engaged over the mandrel; (e) cooling the tubular braid; and (f) disengaging the braid from the mandrel.
Claim 14
Dependent Claim
85 words
12 . A method for manufacturing a stent comprising: (a) providing an elongated mandrel having an outer diameter and at least one local outwardly bound elevation; (b) forming an elongated metallic tubular braid having proximal and distal ends, the braid having an inner diameter commensurate with the outer diameter of the mandrel; (c) engaging the tubular braid over the mandrel; (d) heating the tubular braid while it is engaged over the mandrel; (e) cooling the tubular braid; and (f) disengaging the braid from the mandrel.
Claim 15
Dependent Claim
24 words
13 . The method of claim 12 wherein prior to disengaging the braid from the mandrel the braid is compressed in an axial direction.
Claim 16
Dependent Claim
23 words
14 . The method of claim 12 wherein the steps of heating and cooling the tubular braid are performed under a vacuum condition.
Claim 17
Dependent Claim
16 words
15 . The method of claim 12 wherein the tubular braid is made of spring steel.
