TUBULAR CARDIAC-VALVE PROSTHESIS AND A METHOD OF MAKING IT

摘要

The invention relates to a conduit cardiac-valve prosthesis. Said prosthesis consists of a cylindrical tube or a tube provided with bulbous projections with an integrated support housing comprising a base ring, which bears at least two stanchions that are orientated substantially in the direction of t he ring axis and are connected by an arc-shaped wall that fixes flexible leaflets. The invention aims to improve the physiological properties of said prosthesis. To achieve this, the tube, the support housing and the leaflets consist of a single material, preferably polyurethane or another polymer and form a one-piece body.
