Abstract
A prosthesis having a tubular body of a biocompatible graft material having a proximal end, a distal end, a lumen therethrough, and a sidewall. The prosthesis includes at least one perfusion branch extending from the sidewall of the tubular body and having a proximal end, a distal end, and a lumen therethrough, where the lumen of the perfusion branch is in temporary fluid communication with the lumen of the tubular body. The perfusion branch comprises a self-sealing component, that after predetermined period of time precludes fluid flow out of the distal end of the perfusion branch.

A prosthesis comprising:
- a tubular body of a biocompatible graft material having a proximal end, a distal end, a lumen therethrough, and a sidewall;
- and
- at least one perfusion branch extending from the sidewall of the tubular body having a proximal end, a distal end, and a lumen therethrough, where the lumen of the perfusion branch is in temporary fluid communication with the lumen of the tubular body;
- where the perfusion branch comprises a self-sealing component, that after predetermined period of time precludes fluid flow out of the distal end of the perfusion branch.
A stent-graft comprising:
- a tubular body of a biocompatible graft material having a proximal end, a distal end, a lumen therethrough, at least one stent attached to the graft material and a sidewall;
- at least one branch extending from the sidewall of the stent graft;
- at least one perfusion branch extending from the sidewall of the tubular body having a proximal end, a distal end, and a lumen therethrough, where the lumen of the perfusion branch is in temporary fluid communication with the lumen of the tubular body;
- where the perfusion branch comprises a self-sealing component, that after predetermined period of time precludes fluid flow out of the distal end of the perfusion branch.
