Abstract
A biocompatible polyethylene oxide gel implant and method for production which can be injected into the human body for tissue replacement and augmentation. The implant is prepared by dissolving a sample of essentially pure polyethylene oxide in a saline solution in a sealed canister, removing all free oxygen from the container and replacing it with an inert gas, such as argon, and irradiating the canister with a gamma ray source to simultaneously crosslink the polyethylene oxide while sterilizing it. The gel can then be placed into a syringe and injected into the body.
