In particular, the inner surface of the intravascular stent has at least one groove formed therein.
Claims12
A method of manufacturing an intravascular stent comprising the steps of:
- forming an intravascular stent having an inner surface and an outer surface;
- and forming at least one groove on the inner surface of the stent by a thermal process.
A method of manufacturing an implantable medical device, comprising the steps of:
- providing an implantable medical device having a first surface and a second surface, and forming at least one groove in at least one of the first surface or the second surface, the at least one groove adapted to increase the rate of endothelial cell migration upon the at least one of the first surface or the second surface, the at least one groove being formed by a thermal process.
