| abstract |
The present invention provides porous biologically compatible materials capable of being formed into surgical implants, comprising layers of poly(tetrafluoroethylene) and elastomer, having superior compliance, strength, elasticity and suturability. The materials comprise a first layer of poly(tetrafluoroethylene), a second layer of poly(tetrafluoroethylene)/elastomer mixture, optionally a third layer of elastomer, and an optional fourth layer of a monomer fibrous elastomer matrix. |
