Abstract
The invention concerns an implantable stent (10) with an at least portion-wise polymeric coating (16). The coating material is admittedly intended to bond to known materials but by virtue of its properties it is intended to enjoy improved compatibility and reduce inflammatory and proliferative processes which can lead to restenosis. That is achieved in that the polymeric coating (16) in the implantable condition after production and sterilization contains poly-L-lactide of a mean molecular weight of more than 200 kDa.

15. A process for producing an implantable stent with a polymeric coating of high-molecular poly-L-lactide, comprising the steps of:
-
(a) wetting the stent at least portion-wise with a fine mist of a solution of poly-L-lactide of a mean molecular weight of more than 650 kDa;
(b) drying the solution applied to the stent by blowing; and
(c) sterilizing the stent with electron beam sterilization. - View Dependent Claims (16, 17, 18, 19, 40, 41, 42)
