First Claim
Patent Images
1. A method of modulating thermal, mechanical, and surface properties of a coating and applying the coating on an implantable device, comprising:
- (1) Providing a first polymer, wherein said first polymer has a glass transition temperature less than or equal to 37°
C. and is selected from a poly(ester amide), poly(glycerol sebacic acid), and a low Tg PolyAspirin,(2) Reacting said first polymer with a chemical stiffening agent, wherein the agent is an aromatic diol,(3) Obtaining a second polymer having a Tg higher than the Tg of the first polymer,(4) Forming a coating comprising the second polymer, and(5) Applying the coating on an implantable device.

Abstract
Methods for modulating and enhancing thermal and mechanical properties and biocompatibilities of coatings on implantable devices are disclosed. Implantable devices containing the enhanced thermal and mechanical properties and biocompatibilities are also described. The implantable devices can be used to treat a medical condition such as vulnerable plaque or restenosis.
