Abstract
Systems and methods for managing aneurysms provide additional support to an aneurysmal wall by disposing a flexible vascular liner against or in close proximity to the aneurysmal wall. The liner is flexibly expansive to conform to the wall of the aneurysm. The liner inhibits failure of the aneurysmal wall. The liner may also inhibit further growth in diameter of the aneurysm. Aneurysms in single arteries or near branched arteries may be supported by a flexible vascular liner.
Claims26
An endovascular system for aneurysm management comprising:
- a vascular liner having a proximal open end at a proximal liner portion and an opposed distal open end at a distal liner portion defining an open liner lumen having a liner wall disposed there between and further defining a medial liner portion disposed between the proximal liner portion and the distal liner portion;
- a proximal anchor associated with the proximal liner portion;
- and
- a distal anchor associated with the distal liner portion;
- wherein the liner wall of the medial liner portion is an unitary liner wall not having spaced-apart layers or membranes thereat and not having re-enforcing filaments, strands or stent portions thereat;
- and
- wherein the liner wall of the medial liner portion is flexibly expansive to conform to a wall of an aneurysm to provide additional strength to aneurysmal tissue at the aneurysm wall.
A method for treating an aneurysm comprising:
- providing a vascular system comprising:
- a vascular liner having a proximal open end at a proximal liner portion and an opposed distal open end at a distal liner portion defining an open liner lumen having a liner wall disposed there between and further defining a medial liner portion disposed between the proximal liner portion and the distal liner portion;
- a proximal anchor associated with the proximal liner portion;
- and
- a distal anchor associated with the distal liner portion;
- wherein the liner wall of the medial liner portion is an unitary liner wall not having spaced-apart layers or membranes thereat and not having re-enforcing filaments, strands or stent portions thereat;
- and
- deploying the vascular liner system such that the proximal anchor is disposed proximally beyond an aneurysm and such that the distal anchor is disposed distally beyond the aneurysm;
- and
- expanding the liner wall of the medial liner portion to allow the liner wall of the medial liner portion to conform to a wall of an aneurysm to provide additional strength to aneurysmal tissue at the aneurysm wall.
