Abstract
A bipolar medical device for extracting tissue including a handle, and an outer tube projecting from the handle, the outer tube extending along a longitudinal axis and including a proximal end connected with the housing and a distal end spaced from the proximal end. The medical device includes a split tube disposed within the outer tube, the split tube having a distal end including a first cutting element and an opposing second cutting element, a motor coupled with the split tube for selectively rotating the split tube and the first and second cutting elements about the longitudinal axis, and an electrosurgical generator coupled with the split tube, whereby the first cutting element is connectable with a first pole of the electrosurgical generator and the second element is connectable with a second pole of the electrosurgical generator for passing electrical current between the first and second cutting elements.
