CA 2220039

A microporous polytetrafluoroethylene endovascular graft (10) which has a reinforcing structure (16) integrally bound to the graft which permits radial expansion of the graft and stabilizes the graft against longitudinal compression upon application of an axial force thereto and against axial foreshortening upon radial expansion of the graft. The graft is particularly useful as a covering for an endovascular stent.

L'invention porte sur un transplant endovasculaire en polytétrafluoroéthylène microporeux (10), pourvu d'une structure de renforcement (16) fixée au transplant dont elle devient solidaire, ce qui permet une dilatation radiale de celui-ci et le stabilise à l'encontre de toute compression longitudinale, lors de l'application d'une force axiale, ainsi qu'à l'encontre de tout rapprochement axial, lors de sa dilatation radiale. Ce transplant est particulièrement utile comme revêtement d'un extenseur endovasculaire.
