Abstract: A vessel filter comprising a first region and a second region wherein the filter is movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. A first region has a filter portion having a converging region to direct particles toward the center of the filter and the second region is flared in the expanded position to have a transverse dimension increasing toward a second end portion opposite the first end portion. The second region includes a vessel engaging portion at the second end portion. The first region includes a plurality of spaced apart elongated struts with adjacent struts being joined.

Abstract: A medical device for placing an embolic device at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member slidably disposed within the lumen of the catheter. An embolic device is retained within the delivery catheter by a mechanical interlocking mechanism which includes an engagement member attached to the distal end of the pusher member and extends through a retaining ring at the proximal end of the embolic device. A detachment member extends through an aperture at the distal end of the engagement member thereby locking the embolic device onto the pusher member. A kicker member extends from the distal end of the pusher member and is comprised of a shape memory material adapted to lift the retaining ring off of the engagement member at human body temperature when the detachment member is withdrawn from the aperture of the engagement member.

Abstract: A medical device for placing an embolic device at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member slidably disposed within the lumen of the catheter. A fluid pressure source is coupled to the proximal end of the pusher member. An embolic device is retained at the distal end of the pusher member by a mechanical interlocking mechanism. The distal end of the pusher member includes a spiral ribbon section encircled by a tubular member. The tubular member or the distal end of the pusher member directs fluid from the fluid pressure source against the embolic device. The mechanical interlocking mechanism is disengaged from the embolic device and a fluid pressure is applied against the embolic device to ensure the release of the embolic device.

Abstract: A medical device for placing an embolic device, such as an embolic coil at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member slidably disposed within the lumen of the catheter. An embolic device is retained within the delivery catheter by a mechanical interlocking mechanism which includes a deflectable engagement member attached to the distal end of the pusher member and extends through a retaining ring at the proximal end of the embolic device. A detachment member extends through an aperture at the distal end of the engagement member thereby locking the embolic device onto the pusher member. When the detachment member is withdrawn from the aperture of the engagement member the engagement member deflects to release the embolic device.

Abstract: A vessel filter comprising a mounting section having first and second ends and a first and second filtering section. The filter is movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. In the expanded position a first end of the first filtering section converges to form a first converging region and a second end of the second filtering section converges to form a second converging region. The first converging region is positioned radially and axially inwardly of the first end of the mounting section and the second converging region is positioned radially and axially inwardly of the second end of the mounting section.
