Abstract
The present invention is a system, apparatus, and method for treating, repairing, and/or replacing an aneurysm, preferably an aortic aneurysm, and most preferably, an abdominal aortic aneurysm. The systems, devices, and methods of the present invention include a first prosthesis or stent gasket, and at least one second prosthesis for bypassing the aneurysm, and at least one third prosthesis for establishing a fluid flow channel from the abdominal aorta into another artery, such as a renal artery.
Claims19
A system for bypassing an aneurysm comprising a first prosthesis and at least one second prosthesis communicating with the first prosthesis, and at least one third prosthesis communicating with the first prosthesis;
- said first prosthesis comprising a proximal end configured to engage a section of artery upstream of a junction between a first artery and a second artery, said second prosthesis being configured to bypass the aneurysm, and said third prosthesis being configured to provide a fluid flow channel from the first artery into the second artery.
A system for bypassing an aneurysm comprising a first prosthesis, at least two second prostheses communicating with the first prosthesis, and at least two third prosthesis communicating with the first prosthesis;
- said first prosthesis comprising a proximal end configured to engage a section of artery upstream of a junction between a first artery and a second artery, said second prosthesis being configured to bypass the aneurysm and anchor in an artery downstream of the aneurysm, and said third prosthesis being configured to provide a fluid flow channel from the first artery into the second artery.
A method for bypassing an aneurysm downstream of a junction between a first artery and a second artery comprising positioning a first prosthesis in a first section of the first artery;
- engaging at least one second prosthesis with the first prosthesis, said second prosthesis forming a fluid flow path that bypasses the aneurysm;
- and engaging at least one third prosthesis with the first prosthesis, said third prosthesis forming a fluid flow path into the second artery.
A method for bypassing an aneurysm comprising anchoring a first portion of a first prosthesis upstream of a branch artery, seating a second portion of the first prosthesis downstream of the branch artery, and engaging a second prosthesis to the second portion of the first prosthesis.
