Abstract
A medical article is disclosed, comprising a biologically degradable AB block copolymer and a biologically degradable polymer that is capable, at equilibrium and at room temperature, of absorbing less than about 5 mass % water.
Claims15
A medical article, comprising:
- (a) a medical substrate;
- and
- (b) a coating deposited on the substrate, the coating comprising a first polymer and a second polymer, wherein the first polymer is a biologically degradable AB block copolymer, and the second polymer is a biologically degradable polymer that is capable, at equilibrium and at room temperature, of absorbing less than about 5% water by mass of the biologically degradable polymer,
- wherein the AB block copolymer is capable, at equilibrium and at room temperature, of absorbing about 5% or more water by mass of the AB block copolymer.
