Poly(ester amide) filler blends for modulation of coating properties
First Claim
1. A coating for an implantable device, comprising:
- a poly(ester amide) (PEA) polymer comprising a polymer chain having amide groups in the chain, anda material for hydrogen-bonding with the PEA,wherein the polymer chain of one molecule of the PEA polymer hydrogen-bonds to a molecule of the material for hydrogen-bonding, which in turn hydrogen-bonds to the polymer chain of another molecule of the PEA polymer.

Abstract
Provided herein is a PEA polymer blend and coatings or implantable devices formed therefrom. The PEA polymer blend is formed of a PEA polymer and a material capable of hydrogen bonding with the PEA. The PEA polymer blend can form a coating on an implantable device, one example of which is a stent. The coating can optionally include a biobeneficial material and/or optionally with a bioactive agent. The implantable device can be used to treat or prevent a disorder such as one of atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, and combinations thereof.
