Abstract
Official abstract text for this publication.
A system for treating an aneurysm in a blood vessel or vein, wherein the aneurysm has a dome, an interior, and a neck. The system includes a shape memory polymer foam in the interior of the aneurysm between the dome and the neck. The shape memory polymer foam has pores that include a first multiplicity of pores having a first pore size and a second multiplicity of pores having a second pore size. The second pore size is larger than said first pore size. The first multiplicity of pores are located in the neck of the aneurysm. The second multiplicity of pores are located in the dome of the aneurysm.
First claim
Opening claim text (preview).
1 . An apparatus for treating an aneurysm in a blood vessel or vein, wherein the aneurysm has a dome, an interior, and a neck; comprising: a shape memory polymer foam in the interior of the aneurysm between the dome and the neck, wherein said shape memory polymer foam has pores that include a first multiplicity of pores having a first pore size and a second multiplicity of pores having a second pore size, wherein said second pore size is larger than said first pore size. 2 . A method of treating an aneurysm in a blood vessel or vein, wherein the aneurysm has a dome, an interior, and a neck; comprising the steps of: providing a shape memory polymer foam that has pores that include a first multiplicity of pores having a first pore size and a second multiplicity of pores having a second pore size, wherein said second pore size is larger than said first pore size; and positioning said shape memory polymer foam in the interior of the aneurysm between the dome and the neck of the aneurysm.
