Abstract
Drug loading of polymeric materials can be adjusted by selection of materials and/or adjusting processing steps in formation of an implantable drug-loaded device.
Claims5
A method of forming an implantable medical device, comprising:
- forming an elastomeric polymeric material into a shape of the implantable medical device;
- applying a solvent to the polymeric material so as to load the polymeric material with a therapeutic agent;
- and
- subjecting the polymeric material to a post-curing process including vulcanizing the polymeric material after applying the solvent to the polymeric material, wherein the post-curing process alters a hardness for the polymeric material.
