Abstract

See full text

A bipolar biopsy device for removing tissue samples for biopsy purposes or other purposes. The bipolar biopsy device has an elongated flexible end and a lumen extending therebetween. A cutting head is mounted on the distal end and has a hollow fixed member containing an electrode having an electrical surface thereon and a hollow cup-shaped moveable relative to the fixed member. The electrode surfaces are electrically connected to an outside voltage source. A handle is affixed to the proximal end and a core wire is affixed to the handle which extends through the lumen and is affixed to the movable hollow cup-shaped member. The core wire manipulated by way of the handle facilitates the movement of the movable cup-shaped member. Tissue samples are obtained by positioning the electrode surfaces close to each other about the tissue sample. An arc is created to break tissue down by applying a voltage to the 2 electrode surfaces. The cut tissue remains within the cup-shaped members as the device is withdrawn from the body for later biopsy purposes.
