IMPLANTATION DEVICE FOR STENTS WITH A FUNCTIONALLY STRUCTURED SURFACE
First Claim
1. Implantation device for stents, which device has hair-like extensions, at least on one part of an outwardly-facing surface of a section of the device, which section is provided for the attachment or crimping of the stent to be implanted, wherein the mean diameter D, the mean length L, and averaged center-to-center distance P of the hair-like extensions relative to each other are selected such that a stent is essentially affixable by van der Waals forces on the surface covered with hair-like extensions.

Abstract
The invention relates to an implantation device for stents, which device has hair-like extensions on at least one part of the outwardly-facing surface of that section of the device, which section is provided to attach or crimp on the stent to be implanted, wherein the mean diameter D, the mean length L, and the averaged center-to-center distance P of the hair-like extensions relative to each other are selected such that a stent is affixable on the surface covered with hair-like extensions essentially by means of van der Waals forces.

20. An implantation device for stents comprising:
-
a section of the device configured for attachment to the stent to be implanted, the section having an outwardly facing surface; substantially cylindrical extensions on at least a portion of the outwardly-facing surface, the extensions having a mean diameter D between about 0.05 and about 5 μ
m., a mean length L between about 0.1 and about 20 μ
m, and an average center-to-center distance P between about 0.1 and about 5 μ
m, wherein the ratio of D to L is between about 0.75 and 1.5, the ratio of P to D is between about 1 and 50; and
,a polymer coating on the extensions having a thickness of less than about 100 nm and having catechol side groups.
