BIFURCATED ENDOVASCULAR PROSTHESIS HAVING TETHERED CONTRALATERAL LEG

摘要

An endovascular prosthesis, comprising:a bifurcated and inflatable prosthesis (106) comprising:a main tubular body having an open end and opposed ipsilateral andcontralateral legs defining a graft wall therein between, said ipsilateral and contralateral legs (126, 128) having open ends, and said main tubular body and said ipsilateral and contralateral legs having inflatable channels (136); anda web (210) of biocompatible material disposed between the contralateral leg and the ipsilateral leg and secured to the contralateral leg and the ipsilateral leg;wherein the contralateral leg is restricted from significant longitudinal movement so as to prevent bunching up of the contralateral leg during delivery of the endovascular prosthesis.
