ABSTRACT:
Described is a tissue resection system which includes a guide element; a resection head; a positioning mechanism and an actuating mechanism. The resection head includes a guide channel slidably receiving the guide element and an endoscope channel sized to slidably receive an endoscope therein, so that, when the resection head is slid along the guide element, the endoscope and the resection head follow a path defined by the guide element. The positioning mechanism moves the resection head relative to a distal end of the endoscope between a first position in which the distal end of the endoscope extends distally out of the endoscope channel and a second position in which the distal end of the endoscope is received within the endoscope channel. The actuating mechanism moving a portion of an outer wall of the resection head to open and close a resection chamber defined by the outer wall.
