Title (EN) BIOCOMPATIBLE SYNTHETIC DOUBLE-WALL VASCULAR PROSTHESIS CONTAINING HORMONE-SECRETING CELLS
(FR) PROTHESE VASCULAIRE A DOUBLE PAROI SYNTHETIQUE ET BIOCOMPATIBLE CONTENANT DES CELLULES A SECRETION D'HORMONE
Abstract:
(EN) Biocompatible synthetic double-wall vascular prostheses comprising an outer tubular element (1) made of low-porosity synthetic material and an internal tubular element (2) coaxial with the former and consisting of high porosity synthetic material imbued with polysaccharide material coated with polyaminoacids which impart to the element (2) the feature of a controlled permeability, the space comprised between said element (1) and said element (2) being filled with hormone-secreting cells (3).
(FR) Prothèses vasculaires à double paroi, synthétiques et biocompatibles, comprenant un élément tubulaire externe (1) fabriqué à partir d'un matériau synthétique de faible viscosité et un élément tubulaire interne (2) coaxial avec le premier et composé d'un matériau synthétique de porosité élevée imprégné d'une matière de polysaccharide enduite d'acides polyaminés qui confèrent à l'élément (2) une caractéristique de perméabilité contrôlée, l'espace compris entre ledit élément (1) et ledit élément (2) étant rempli de cellules à sécrétion d'hormone (3).
