摘要： A device for delivering an embolic coil to a selected site within a vessel in a human body via use of a catheter. In particular, the device involves an embolic coil having an enlarged member, such as a ball attached thereto which coil is released by forcing the enlarged member through an aperture in a socket situated on the distal end of a pusher assembly.

摘要： This is an implant for placement in the human body and an assembly for so placing that implant. Most desirably, it is an implant for use in the vasculature of the human body and is used to occlude some space in that vasculature as a portion of a treatment regimen. The implant itself is preferably a component of a deployment device using an electrolytically severable joint. The implant is electrically isolated from the electrolytically severable joint by a highly resistive or insulative layer. Such isolation and minimization of the conductive pathway from the placement apparatus to the body's fluids appears to enhance the susceptibility of the electrolytic joint to quick erosion and detachment of the implant from the deployment media. Although the implant itself is preferably a vaso-occlusive device, it may instead be a stent, a vena cava filter, or other implant which may be installed in this manner.

摘要： 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.
