Appl. No.:

10/175210

Inventors:

Ralph A. Chappa - Prior Lake MN, US
Robert W. Hergenrother - Eden Prairie MN, US

Assignee:

SurModics, Inc. - Eden Prairie MN

International Classification:

A61F 2/02

US Classification:

424423

Abstract:

A coating composition in the form of a one or multi-part system, and method of applying such a composition under conditions of controlled humidity, for use in coating device surfaces to control and/or improve their ability to release bioactive agents in aqueous systems. The coating composition is particularly adapted for use with medical devices that undergo significant flexion and/or expansion in the course of their delivery and/or use, such as stents and catheters. The composition includes the bioactive agent in combination with a first polymer component such as polyalkyl(meth)acrylate, polyaryl(meth)acrylate, polyaralkyl(meth)acrylate, or polyaryloxyalkyl(meth)acrylate and a second polymer component such as poly(ethylene-co-vinyl acetate).
