Abstract
A method and apparatus for managing polyps by which an elongated tubular member generally positionable within the working channel of an endoscopic device. The tubular member carries a selectively extendable severing device and capturing device at its distal end. Control apparatus at the proximal end of the tubular member enables a physician to extend and retract the severing and capturing devices. The physician retracts the capturing device to grasp the portion of the polyp to be severed and retracts the severing device to sever the polyp. The capturing device retains the severed portion of the polyp for removal with the tubular member. In one embodiment the capturing device includes an injection needle.
