Abstract: A device for morcellating tissue within a body cavity of a patient comprises a stationary tube having a distal end portion, and a bipolar electrosurgical electrode assembly located at the distal end of the tube. The electrosurgical electrode assembly comprises first and second electrodes separated by an insulation member, the bipolar electrosurgical electrode assembly extending around the circumference of the distal edge of the tube. When an electrosurgical cutting voltage is applied to the electrode assembly, and relative movement is initiated between the tube and the tissue, a core of severed tissue is formed within the tube such that it can be removed from the body cavity of the patient. A tissue-pulling device such as a jaw assembly can be employed to pull tissue against the distal end of the tube.

Abstract: A series of templates having a predetermined shape, the combination of shapes corresponding to the shape of most of the commercially available electrical junction boxes. A selected template is positioned on a surface, temporarily secured to the surface, and an outline along the edges of the template then being formed on the surface. A cutout is formed along the outline on the surface and the cut part removed. The electrical junction box is then secured within the opening formed by the cutout.
