Vascular prosthesis and instrument for placing it in position

Abstract

Abstract The prosthesis consists essentially of a tubular sleeve having, on its outer lateral surface, oriented raised parts, of which a fraction, possibly as much as half, is reversed in relation to the others. The instrument for its positioning comprises a flexible central core serving as a guide, a tubular outer sheath which is flexible and designed at its distal end in such a way as to temporarily hold the prosthesis previously passed over the abovementioned central core, as well as a flexible tubular member sliding between the central core and the sheath and constituting a rear stop ensuring that the prosthesis is held in the distal part of the said device. Application in particular as a prosthesis of the biliary tracts or for portacaval anastomosis.
