Supra-renal anchoring prosthesis
View Patent ↗A system, apparatus, and method for treating, repairing, an aneurysm, preferably an aortic aneurysm, and most preferably, an abdominal aortic aneurysm as described herein. The systems, devices, and methods described herein include a first prosthesis or stent gasket, and at least one second prosthesis for bypassing the aneurysm. The first prosthesis is configured and adapted to accommodate a section of artery upstream of the aneurysm, wherein the section is unsuitable for anchoring a typical first prosthesis.
1. A system for bypassing an aneurysm comprising a first prosthesis and at least one separate and distinct bypass prosthesis, including at least one stent and graft material in fluid communication with the first prosthesis, the first prosthesis comprising a stent structure including a proximal section configured to engage a healthy section of artery above a branch artery upstream of an aneurysm, a distal section, and an intermediate section disposed between the proximal and distal sections, the proximal section comprising a substantially diamond like lattice configuration, the distal section comprising a substantially diamond like lattice configuration and a plurality of longitudinally extending legs, the intermediate section comprising a plurality of struts extending substantially orthogonal between the proximal and distal sections and configured to allow blood flow through the branch artery, the distal section comprising a sealing material attached thereto, the sealing material being distinct from the graft material and comprising a compressible foam, the distal section being configured to receive the at least one separate and distinct bypass prosthesis, the at least one separate and distinct bypass prosthesis passing through the distal section whereby the sealing material seals the first prosthesis to the wall of the artery and the first prosthesis to the at least one separate and distinct bypass prosthesis.
2. The system of claim 1 wherein a proximal portion of the distal section is configured to receive a proximal portion of the at least one separate and distinct bypass prosthesis.
3. The system of claim 1 wherein the distal section is configured to receive two separate and distinct bypass prostheses.
