摘要： A cardiac support device and placement tool assembly. The cardiac support device has a flexible jacket with an open base end. The placement tool includes a cannula having an open end, a collapsible support on the end of the cannula releasably connected to the cardiac support device at a plurality of locations around the base end, and an acutuator. The collapsible support is movable between a collapsed state in a retracted position at which the collapsible support and cardiac support device are within the end of the cannula, and an open state in an extended position at which the collapsible support and cardiac support device are outside of the cannula with the collapsible support holding the base end of the cardiac support device in an open position for placement onto a patient's heart. The actuator moves the collapsible support between the collapsed and open states.

摘要： A gastric reduction pouch of a stomach is formed by gathering stomach tissue circumferentially from within the stomach to form a reduced diameter stomach section. A plurality of fasteners are deployed within the gathered stomach tissue to maintain the reduced diameter stomach portion. The gathering step may include folding the stomach tissue to produce a plurality of stomach tissue folds.

摘要： A constriction device that constricts body tissue is viewable under X ray fluoroscopy. The device includes an elongated sleeve. The sleeve includes opposed opened ends and is formed from expandable or elastic material to receive therein, when in an expanded condition, body tissue to be constricted and to constrict the body tissue therein when released from the expanded condition. At least a portion of the sleeve includes X ray opaque material rendering the device visible under X ray fluoroscopy.

摘要： A resection device and method permits safe and efficient encapsulation, isolation and resection of body tissue. The device includes a sheath of flexible and severable material configured to receive the body tissue to be resectioned as it is drawn therein. The sheath may be expandable and held in an expanded condition as the body tissue to be resectioned is drawn into the sheath. Thereafter, the sheath is permitted to collapse about the body tissue to contain and constrict the body tissue. Once the body tissue to be resectioned is disposed in the sheath, the sheath is severed to resection the body tissue.
