Stent with protective pads or bulges
First Claim
1. A method of making a stent having at least one strut having an outer surface, and at least one pad that projects from the outer surface of the strut, the method comprising:
- (a) obtaining a tube having an outer surface, wherein the tube comprises a tube material;
(b) connecting at least one pad-forming component having an inner surface to the outer surface of the tube, wherein the pad-forming component comprises a component material; and
(c) removing a portion of the tube material from the tube to form the strut;
wherein the at least one pad-forming component forms the at least one pad wherein the at least one pad has a bearing surface.

Abstract
A stent having at least one strut comprising at least one pad or bulge is disclosed. The pads or bulges are of a height that are preferably slightly greater than the thickness of a coating that can be disposed on the strut. The coating is not disposed on the pads. When the stent is placed within a delivery member such as a sheath or a catheter, the pads or bulges contact the inner surface of the delivery member, preventing the coating from contacting the inner surface. Damage to the coating that may be caused by friction with or adhesion to the delivery member is thus prevented. Methods for forming such a stent are also discussed.

19. A method of making a stent comprising at least one strut having an inner surface and an outer surface, wherein the strut comprises at least one pad that projects from at least one of the inner surface or the outer surface of the strut, the method comprising:
-
(a) obtaining a tube having an inner surface, an outer surface, and at least one pad-forming projection integral with and projecting from at least one of the tube inner surface or the tube outer surface; and
(b) forming the strut comprising the pad projecting from at least one of the inner surface or outer surface of the strut, wherein the pad comprises a bearing surface. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method of making a stent comprising at least one strut having an inner surface and an outer surface, wherein the strut comprises at least one strut bulge that projects towards at least one of the inner surface or the outer surface of the strut, the method comprising:
-
(a) obtaining a tube having a tubular wall comprising an inner surface and an outer surface, a first end, a second end and a lumen therein;
(b) deforming the tubular wall to form at least one tubular wall bulge extending towards at least one of the tubular wall inner surface or the tubular wall outer surface; and
(c) forming the strut comprising the strut bulge, wherein the strut bulge is at least a portion of the tubular wall bulge and wherein the strut bulge comprises a bearing surface. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
