PTFE coating for metal mesh prosthesis used in artery expansion - internal and external coatings are applied to mesh and prevent thrombosis and further arterial restriction

Abstract

Abstract A prosthesis is described which consists of an expandable metal wire mesh (2). The prosthesis has a thin coating (3) of polytetrafluoroethylene on the inner surface. A further coating (4) can if necessary be applied to the outer surface. The PTFE (3) can be applied to the mesh (2) as a film and sintered, as a tube which can be stitched around the mesh (2) or as a dispersion which is sintered. USE/ADVANTAGE - As a prosthesis for insertion into restricted arteries for maintaining a constant expansion of the restricted canal. Onset of thrombosis is prevented and cell growth through the grid is prevented thus avoiding further arterial restriction.
