Abstract
The invention comprises a method for removal of tumor tissue from a patient's body. The method generally comprises the steps of providing an apparatus comprising an elongate member for receiving tissue. The elongate member defines a lumen and comprises a distal end defining an aperture and a proximal end. The apparatus further comprises an elongate tissue removal member for conveying tissue through the lumen. The tissue removal member is rotatably disposed within the lumen.
