Abstract
A delivery device and method for intraluminally deploying a clip appliance within a body lumen or cavity of a patient, for example a vein. The clip is configured from a wire-like, bendable material, having a "W"-like sinusoidal shape. The clip is constructed with sharpened slanted edges at the tips which provide preferential bending and straightening when the clip is deployed into patient tissue, for example, a venous valve. The delivery device comprises a catheter and a structure for bending and releasing the clip. The catheter is configured with an elongate flexible tubular member secured to a slotted housing having a distal tapered tip. A handle is secured to the proximal end of the flexible tubular member. A balloon and actuator arm combination is disclosed for forcing a clip against an anvil to bend the clip from an open to a closed condition and for releasing the clip from a slot in a side wall of the housing. The housing may be configured to retain and deploy a plurality of clip appliances. During clip deployment, the catheter housing is positioned within a vessel or viscus of a patient, and the slot in the side wall is precisely aligned and stabilized with a second inflatab…
