<p>A polymer composition comprises cross-linked polyethylene having a non-polar biocompatible lipid disposed in at least a portion of the free volume of the polyethylene, comprising at least one of squalane, fatty acids, glycerides, polyisoprenoids, cholesterol and cholesterol esters. The composition can be made by a method which involves contacting a polymer preform with a solution of the lipid, and irradiating the polymer preform so that it becomes crosslinked.</p> |
