Patent Images
1. A system for the treatment of an aneurysm, the system comprising:
- —
an aneurysm filling component and a delivery device;
the aneurysm filling component comprising a polymeric component;
the polymeric component having a cohesive energy density of less than 60 cal/cm3 and an internodal distance of less than 200 microns;
the delivery device comprising a catheter;
and the aneurysm filling component configured to be delivered through the catheter to a target aneurysm.

Abstract
An embolic occlusion device for the treatment of aneurysms and arteriovenous malformations comprises expanded polytetrafluoroethylene (ePTFE). The ePTFE permits ingrowth of cells with connective tissue deposition to promote adherence of the aneurysm wall to the embolic device thereby preventing continued growth or re-growth of the aneurysm as well as blocking blood flow into an aneurysm. An occlusion device is also described which comprises an embolic element and a polymeric pre-formed component.

13. A method for the treatment of an aneurysm, the method comprising:
- —
advancing a first aneurysm filling component through a delivery catheter to a target aneurysm; deploying a first aneurysm filling component into the aneurysm so that it contacts at least a portion of the wall of the aneurysm; advancing a second aneurysm filling component through a delivery catheter to the target aneurysm; and deploying the second aneurysm filling component into the aneurysm so that it at least partially sits within the space defined by the first aneurysm component. - View Dependent Claims (14)
