ABSTRACT:
This is a vasoocclusive device which, as used, is in the approximate shape of an anatomical cavity. It may be deployed as a sphere, an ovoid, or other distorted spherical shape. The device is a self-forming shape made from a pre-formed vasoocclusion member. Prior to deployment, the vasoocclusive device is sufficiently straight that it is able to be pushed from a vascular catheter without excessive friction. The vasoocclusion member may be a small helical coil or braid variously comprising a suitable metal, or, in the case of a braid, such metal may be co-woven with various polymeric or natural fibers. Fibers may be introduced onto the device and affixed to the member. The constituent member may be also be covered with a fibrous braid. The device is typically introduced through a catheter. The device is passed axially through the catheter sheath and assumes its form upon exiting the catheter without further action. The invention also includes methods of winding the anatomically shaped vasoocclusive device into appropriately shaped forms and annealing them to form various devices.
