ABSTRACT:
A composition of matter, and the method of making same, suitable for in vivo implantation to provide an environment in which normal tissue growth is fostered, which composition is a porous, fibrous structure of polytetrafluoroethylene fibers and resin, wherein the combination is sintered at a temperature which fuses the fibers together without substantial detriment to their tensile strength. The composition is prepared containing a material which is soluble in a suitable solvent, which subsequent to sintering of the composition, may be removed to produce the desired amount of void space in the composition.
