Abstract
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.
Claims20
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.
An endoluminal prosthesis, comprising:
- a graft having a bifurcated body comprising a biocompatible material, the graft having proximal and distal ends and a lumen extending therebetween, the bifurcated body having first and second limb portions extending distally from a generally tubular proximal portion;
- first and second proximal graft passageways extending through a sidewall of the proximal portion of the graft;
- and
- a first limb extension attached to and extending distally from the first limb portion, the first limb extension having a passageway through a sidewall thereof.
A method of delivering an endoluminal prosthesis to a patient's body, the method comprising the steps of:
- delivering a bifurcated body having a proximal portion and a distal portion to a vessel of a patient's body, wherein the distal portion includes first and second limb portions extending distally from the proximal portion;
- delivering, to a distal end of the first limb portion, a first limb extension having a first passageway therein;
- adjusting the longitudinal and circumferential location of the first passageway to correspond to the location of a first artery ostium;
- and
- in response to adjusting the location of the first passageway, mating a proximal end of the first limb extension with the distal end of the first limb portion.
