Abstract:
An elongated device for separation of a tissue specimen from a target tissue site, comprising:a. an elongated probe which has a proximal end, a distal end, a longitudinal axis, an inner lumen extending within the probe and which has a distal extremity with at least one aperture in a wall thereof that is in fluid communication with the inner lumen extending within the probe and with a transverse dimension substantially less than portions of the probe distal to the distal extremity; and b. a first tissue cutting electrode which is at least partially disposed about the elongated probe, which lies in a plane transverse to the longitudinal axis of the probe, which has an inner dimension substantially greater that the small transverse dimension of the distal extremity of the probe, which is configured for longitudinal movement along a length of the distal extremity of the probe and which is configured to be electrically connected to a high frequency power source.
