摘要:
A medical apparatus and method useful for resecting tissue from the gastrointestinal tract are disclosed. The apparatus can include an RF tissue cutting device (20) disposed inward of a side opening (34) in the device. A tissue stop (36) can be used to control the depth of tissue resected, and the tissue stop (36) can include holes for communicating vacuum for drawing tissue into the side opening (34). The tissue stop (36) can be electrically grounded with respect to the RF tissue cutting device, and the tissue stop can provide one pole of an RF electrical circuit.

摘要:
A method and a kit for removing a vessel from a patient's body comprises the steps of identifying the vessel to be removing and providing an incision in the patient's body near the identified vessel. An optical dissector is inserted through the incision and tissue is optically dissected away from the surface of the vessel with the optical dissector. The optical dissector is then withdrawn from the body through the incision. An optical retractor is inserted into the body through the incision and is used to retract the dissected tissue away from the surface of the vessel thereby providing space between the dissected vessel and the retracted tissue. The vessel and its side branches are then dissected, ligated and transected and the vessel is then removed from the body through the incision.
