ABSTRACT:
A covered self-expanding vascular occlusion device and a method of making and using the device. The device comprises a braided wire member with at least two axially spaced securing members affixed to the braided wire member and a thin film covering at least half of the device. The braided member can be moved between a larger diameter ball-like shape or conical shape in its relaxed position, and a smaller diameter cylindrical shape in its stretched position. The film covering is applied to the device by first stretching a portion of film to form a shape similar to a portion of a device to be covered by the film, then inserting the device into the shape formed in the film so that the film covers at least half of the device, and trimming the film to separate the covered device from the remaining film. The device is used by installing it on the end of a tubular introducer where it is held in its relaxed position until needed. A sliding member inside of the introducer tube then pulls the device into the tube, moving the device to its stretched position as it does so. The sliding member is pulled out of the tube, releasing the device and leaving it inside of the tube and in its stretched condition. The tube is installed in a catheter and the device pushed from the tube into, through, and out of the catheter where upon exiting the catheter the device then opens to its relaxed condition, lodges in the blood vessel, and immediately and completely occludes the vessel.
