Abstract
An aneurysm closure device or flow diverter includes a frame member formed of crossing frame elements and a diverter portion formed of a plurality of blade elements extending in radially opposing directions from a diverter element. The flow diverter is ideally suited for diverting the flow of fluid from an aneurysm at a vessel bifurcation, whereupon the blade elements and diverter element can be positioned at the neck of the aneurysm so as to substantially close off the flow path into the aneurysm sac. The crossing frame elements hold the device in position at the bifurcation. The structure provides reliable deployment of the device and closure of an aneurysm.
Claims20
A vascular flow diverter including:
- a frame member having first and second ends, the frame member including a support element at the first end and a plurality of frame struts extending from the support element towards the second end, the frame struts each being substantially circular and in a form of a broken ring open at the second end of the frame member;
- and
- a diverter element including a plurality of blade elements attached to and extending from the support element of the frame member, the blade elements being resiliently deformable and having a non-biased condition in which the elements extend radially outwardly from the support element and away from the frame struts.

- a diverter element including a plurality of blade elements attached to and extending from the support element of the frame member, the blade elements being resiliently deformable and having a non-biased condition in which the elements extend radially outwardly from the support element and away from the frame struts;
- wherein the blade elements curve in a direction away from the frame member when in the non-biased condition;
- and
- wherein in the non-biased condition the blade elements are concave when viewed in a direction from the first end to the second end of the frame member.
