ABSTRACT:
An obstructed canal of the human or animal body delimited by a wall is treated by: (a) selectively damaging extrinsic tissue by introducing a controlled dose of ionizing or non-ionizing treatment energy in order to necrose at least a part of the tissue; (b) fitting a prosthesis into the natural canal, the prosthesis including a tubular element biologically compatible with the wall, exerting on the latter a centrifugal compression, and optionally imparting a posture, and defining an open and permanent passage in the natural canal; (c) permitting the extrinsic tissue to heal on and around the prosthesis; and (d), after healing of the extrinsic tissue, extracting the prosthesis from the natural canal to obtain in the latter a definitive passage modeled on the external dimensions of the prosthesis.
