Abstract
Lubricious medical devices such as catheters and stents which minimize friction and retain lubricity and dimensional properties for a long period of time. The devices are made by coextrusion wherein the inner layer is a hydrophobic polymer and the outer layer is a blend of a hydrophilic polymer and hydrophobic polymer. Devices made by extrusion of a blend of hydrophobic polymer with a blend of hydrophobic/hydrophilic polymer are described also.
