Abstract

An auxiliary electromagnetic thermal treatment apparatus (100) for use with an endoscope is provided. The apparatus includes a handle portion (102) and an elongate portion (104) connected to the handle portion (102). The elongate portion (104) includes at least one delivery tube (116) having a memory portion (120) comprised of a shape memory material, and defining a normally unstressed curved configuration. The one delivery tube (116) is moveable relative to the handle portion (102). An electromagnetic probe (124) is disposed within the delivery tube (116), and is moveable relative to the delivery tube (116) to extend a probe end portion beyond the delivery tube (116) into tissue. A first actuator (108) is mounted to the handle portion (102), and connected to the delivery tube (116) to move the delivery tube (116) between a first retracted position and a second advanced position. A second actuator (110) is also mounted to the handle portion (102), and is connected to the probe (124) to extend the probe (124) beyond the delivery tube (116).
