    摘要: An apparatus comprises a strap and an inflatable bladder secured to the strap. The apparatus is sized and configured to wrap along a first plane to encompass an anatomical feature such as an esophagus or stomach. The bladder may have a cross-sectional profile that is asymmetric about the first plane, such as a tapered profile or a contoured profile. The wall thickness of the bladder may be substantially uniform or may vary about the perimeter of the bladder. The bladder may include an expansion section that allows the bladder to transition from having a substantially flat cross-sectional configuration in a non-inflated state to having a substantially tapered cross-sectional configuration an inflated state. The expansion section may include folds, pleats, gussets, or the like. The strap may have a cross-sectional profile that is asymmetric about the first plane. Such a strap may include annular ribs of varying sizes.

    摘要: Methods and devices are provided for rotating an end effector on a long, flexible medical device. The methods and devices utilize an actuator mechanism that is effective to rotate an end effector on the distal end of an elongate flexible shaft. The actuator mechanism is movable between a freely rotatable position and a rotationally resistant position. When the actuator mechanism is in a freely rotatable position, the actuator mechanism can be rotated to impart torque to the end effector, and thus at least a distal portion of the elongate shaft, to cause the end effector to rotate. In order to prevent the actuator mechanism from “freewheeling,” wherein the actuator mechanism freely rotates in an opposite direction upon release rather than the end effector rotating in the desired direction, the actuator mechanism can be moved to the rotationally resistant position.

    摘要: An endoscopic vessel harvesting device and a method of endoscopic harvesting of vessels from a patients body. The method comprises locating the vessel, and inserting the vessel harvesting device through an incision. Dissecting the vessel from the surrounding tissue, and capturing side branch vessels in a vessel capturing device. Ligating and transecting the side branch vessels using electrodes and a knife located in the vessel capturing device. Finally, ligating and transecting the vessel, and removing the vessel from the patients body. The vessel harvesting device comprises a head piece, a shaft having a lumen for receiving an endoscope, and a vessel capturing device located on the head piece for capturing the side branch vessels in the receiver.
