초록 ▼

The invention relates to methods and apparatus for manufacturing intravascular stents wherein the intravascular stent has its inner surface treated to promote the migration of endothelial cells onto the inner surface of the intravascular stent. In particular, the inner surface of the intravascular s

대표청구항 ▼

1. A method of manufacturing an intravascular stent comprising the steps of: forming an intravascular stent having a longitudinal axis; an inner surface and an outer surface; and forming at least one groove on the inner surface of the stent by a thermal process, wherein the at least one groove is disposed in a cross-hatched manner, substantially parallel with the longitudinal axis, or substantially perpendicular with the longitudinal. 2. The method of claim 1, wherein the thermal process further comprises electric discharge machining. 3. The method of claim 1, wherein the thermal process further comprises laser etching. 4. The method of claim 2, further including the steps of: inserting an electric discharge machining electrode into the stent; moving the electrode within the stent; and providing current to the electrode to cut at least one groove into the inner surface of the stent. 5. The method of claim 3, further including the steps of: directing laser energy onto the inner surface of the stent and imparting relative movement between the laser energy and the inner surface of the stent to form the at least one groove into the inner surface of the stent. 6. The method of claim 5, wherein the implantable medical device further comprises a tubular device and the method further comprises the step of introducing thermal energy from a thermal energy source to a lumen of the tubular device, relatively moving the thermal energy source and the tubular device while applying the thermal energy to an inner surface of the tubular device to form the at least one groove. 7. The method of claim 6, wherein the thermal energy is one of electric and optical. 8. The method of claim 7 wherein the electric thermal energy further comprises electric discharge machining. 9. The method of claim 7, wherein the optical thermal energy further comprises laser. 10. The method of claim 9, wherein the thermal process further comprises laser etching.
