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.

Surgical snare with electrosurgical tip and method of use

A surgical retractor for use in combination with balloon dissection of internal body tissue of a human body part to maintain an operative space created by the dissection of the internal body tissue. The retractor has a frame comprising a base with opposing sides and at least one arcuate body tissue support element extending upwardly from one side to the other side of the base so as to form an arc extending transversely over a human body part wherein internal body tissue is to be balloon dissected. As least one suture anchor element is located along the length of the arcuate support element to allow a tensioning suture extending from separated internal body tissue of the human body part being balloon dissected to be secured thereto to maintain an open operation cavity. The suture tied at one end to the suture anchor element includes a disk or suture button at the other end that is urgingly retained against the top portion of the operation cavity to facilitate maintaining an open cavity for a surgical procedure.
