Abstract

A method and device for tissue removal. The device may be used to remove uterine fibroids and other abnormal gynecological tissue. According to one embodiment, the device includes a housing, an outer tube, and an inner tube. The outer tube is fixed to the housing and includes a side window proximate to its distal end. The side window may have sloped proximal and distal ends. The inner tube has a distal end positioned within the outer tube, the distal end being adapted to rotate and, at the same time, to move back and forth past the side window, with the rotational and translational movement of the inner tube being independently controllable. The distal end of the inner tube may have an external bevel. Suction is applied to the proximal end of the inner tube to draw tissue into the side window and to remove resected tissue through the inner tube.
