Prosthesis for promoting the in vivo reconstruction of a hollow organ or a portion of a hollow organ

A prosthesis for promoting the in vivo reconstruction of a hollow organ or of a portion of a hollow organ, wherein said prosthesis comprises:

• a biodegradable hollow tubular support member comprising at least one biocompatible and biodegradable polymer material, said support member being constituted of a porous outer layer and an essentially non-porous inner layer;
• and
• a material of living biological origin at the outer surface, or within at least one portion of the porous layer of said support member, or over the surface of the essentially non-porous layer facing the porous layer, said material of biological origin allowing the in vivo reconstruction of said organ or of said organ portion, said material of biological origin.

A porous biocompatible and biodegradable polymer material for the surgery of a hollow organ of tubular shape, said polymer material being intended to form the porous layer of a biodegradable hollow tubular support member comprising or constituted of a porous outer layer and an essentially non-porous inner layer.

A non-porous biocompatible and biodegradable polymer material for the surgery of a hollow organ of tubular shape, said polymer material being intended to form the non-porous layer of a biodegradable hollow tubular support member comprising or constituted of a porous outer layer and an essentially non-porous inner layer.
