ENDOLUMINAL PROSTHESIS HAVING MODULAR BRANCHES AND METHODS OF DEPLOYMENT

摘要

The present embodiments provide an endoluminal prosthesis having modular branches, and systems and methods for facilitating deployment of the endoluminal prosthesis. In one example, the endoluminal prosthesis comprises a graft including a bifurcated body of a biocompatible material. The bifurcated body includes distally extending limbs. Limb extensions can be longitudinally and circumferentially adjusted prior to mating with the limbs to enable an “off-the-shelf” prosthesis that can conform to various complex anatomy. When adjusted and mated, fenestrations in the limb extensions can align with branch vessels.

1. A modular stent-graft apparatus, the apparatus comprising:
a graft comprising biocompatible material, the graft having a proximal and distal end; a generally tubular proximal portion of the graft with a lumen extending therethrough; first and second limb portions of the graft extending distally from a bifurcation point of the proximal portion and having distal ends, the first and second limb portions each having lumens extending therethrough, the lumens of the limb portions being in fluid communication with the proximal portion lumen; at least one limb extension comprising biocompatible material, the at least one limb extension having a proximal end and a distal end and a lumen extending therebetween, the at least one limb extension dimensioned to engage one of the first and second limb portion; and at least one passageway though a sidewall of the at least one limb extension disposed between the proximal and distal ends of the at least one limb extension.
