  • Publication number: 20130041372
    Abstract: A medical device includes a tissue dissector and a snare loop on a common shaft. At least the distal tip of the snare loop is energizable to function as an electrosurgical element for tissue dissection. In use the snare loop is partially extended from the shaft to expose the electrosurgical element for electrosurgical dissection, and the snare loop is fully extended from the shaft to deploy the snare loop for retrieval and positioning of an implant such as a gastric banding device. The snare loop may be deployed through a pair of jaws also mounted on the shaft for use in tissue dissection.

  • Publication number: 20110230723
    Abstract: An access system for surgical procedures includes an insertion tube having a distal end and a lumen, a pair of instrument delivery tubes extending through the lumen of the insertion tube, each instrument delivery tube having a fixed longitudinal position relative to the insertion tube and a steerable distal portion positioned distal to the distal end of the insertion tube. Proximal actuators are moveable to steer the distal portions of the instrument delivery tubes through manipulation of the handles of instruments extending through those tubes. First and second rigid tubes are mounted within the lumen, at least one of which has a distal end disposed within the lumen.

  • Publication number: 20110029010
    Abstract: A medical dissector having an elongate flexible shaft and dissecting jaws. The jaws moveable from opened to closed and from closed to open using pull actuation of an elongate actuation members such as a pull cables. A first pull cable controls opening of the jaws, while a second pull cable controls closing of the jaws. The shaft and jaws of the instrument are axially rotatable relative to the handle to rotate the jaws about the longitudinal axis of the shaft.
