Patent ID: 8202529

Claim:
An implantable medical device comprising: a device body; and a soluble coating comprising, a primer layer disposed over the device body, wherein the primer layer comprises either a hydrophilic polymer or an amphiphilic polymer; a reservoir layer disposed over the primer layer, wherein if the primer layer comprises a hydrophilic polymer the reservoir layer comprises an amphiphilic polymer or alternatively if the primer layer comprises an amphiphilic polymer the reservoir layer comprises a hydrophilic polymer; and a layer disposed over the reservoir layer, wherein if the reservoir layer comprises a hydrophilic polymer the layer disposed over the reservoir layer comprises an amphiphilic polymer or alternatively if the reservoir layer comprises an amphiphilic polymer the layer disposed over the reservoir layer comprises a hydrophilic polymer, wherein the soluble coating solvates completely within about 30 days after deployment of the implantable medical device; and wherein the one or more hydrophilic polymers are independently selected from the group consisting of polyvinylpyrrolidone, poly(carboxymethyl cellulose) and poly[N-(2-hydroxypropyl)methacrylamide].
