摘要
A porous three-dimensional structure of polytetrafluoroethylene was created featuring an enhanced ability of soft tissue ingrowth, or, in the second embodiment, combining the properties of an enhanced ability of soft tissue ingrowth with a barrier for the deposition of the living tissue cells. In the first embodiment of the porous three-dimensional structure of polytetrafluoroethylene it contains the open through pores and the blind pores, uniformly distributed over the inner surfaces of the open pores and connected therewith, and is made of mixture of the free-flow polytetrafluoroethylene having the granules sized from 100 to 300 microns, and the constraint-flow polytetrafluoroethylene having the granules sized up to 20 microns. In the second embodiment of the porous three-dimensional structure at least one surface of the three-dimensional body is provided with a barrier layer.
