PCT No. PCT/FR97/00734 Sec. 371 Date Jun. 3, 1998 Sec. 102(e) Date Jun. 3, 1998 PCT Filed Apr. 24, 1997 PCT Pub. No. WO97/41804 PCT Pub. Date Nov. 13, 1997A vascular prosthesis to be implanted by the percutaneous endoluminal route is provided according to an embodiment of the invention. The vascular prosthesis includes a flexible sleeve to channel blood therein, and a tubular armature (or stent) to which the sleeve is connected essentially coaxially, the armature being capable of having a first diameter or a second diameter larger than the first, so that the prosthesis is in the form of a single tube or bifurcated tube assuming a radially constricted state for its percutaneous vascular implantation, or a radially opened out state, once it is vascularly implanted, additionally including a vascularly anastomosable terminal portion of sleeve which extends, or is added onto, the flexible sleeve, beyond the armature, this portion being therefore suitable to be anastomosed, in particular by suture, to at least one vessel or vessel substitute. |
