摘要:
This invention is generally related to methods of forming coatings for implantable medical devices, such as drug delivery vascular stents. The methods are for forming coatings to control the release of a peptide such as RGD, and a hydrophobic drug. Both single layer and multiple layer coating constructs are encompassed in the various embodiments of the present invention.
摘要:
The present invention is directed to polymeric materials (e.g., coatings) comprising biodegradable copolymers and implantable devices (e.g., drug-delivery stents) formed of such materials. The biodegradable copolymers are derived from at least two relatively polar monomers and at least one relatively nonpolar monomer. Incorporation of at least one relatively nonpolar monomer into the copolymer improves controlled release of a hydrophobic drug from the polymeric material by increasing the copolymer's miscibility with and permeability to the hydrophobic drug. The polymeric materials can also contain at least one biocompatible moiety, at least one non-fouling moiety, at least one biobeneficial material, at least one bioactive agent, or a combination thereof. The polymeric materials are designed to improve the mechanical, physical and biological properties of implantable devices formed thereof.
摘要:
This invention is generally related to coatings for implantable medical devices, such as drug delivery vascular stents. The coating includes a drug reservoir layer above the outer surface of the device body, the drug reservoir layer with a peptide or protein, a hydrophobic drug, and a polymer with a weight average molecular weight between about 10,000 to about 150,000 Daltons. A preferred polymer is a poly(ester amide) polymer.
