An implant is suitable for treatment for nerve tissue injuries of various types in any period of the severe injury to the nerve tissue, in particular, of the spinal cord, immediately after relief of disturbed vital functions for the early and stable restoration of its conduction in the acute period, prevention from or reduction of the demyelination processes. The technical result is to ensure the possibility to restore the injured nerve tissue in volume. The implant is the body made from porous material, such as the porous PTFE having three-dimensional structure containing the open through pores and dead-ended pores uniformly distributed over inner surfaces of the open pores and connected with the inner surfaces; pore sizes are randomly distributed within the range of 150-300 μm. The method of treatment for nerve tissue injuries and use of the porous PTFE for manufacture of the implant are also claimed.
