Device and method for shielding the urethra and bladder

摘要

A device for managing heating energy from a probe comprises a sleeve including a lumen sized to receive the probe therein, the sleeve defining a first window which, when the sleeve is in a desired position, faces target tissue to which the probe is to deliver energy and a shield element protecting non-target tissue from energy emanating from the surgical probe, the shield element being formed of one of a material reflecting energy delivered by the probe and a material absorbing energy delivered by the probe in combination with a positioning element which, when the sleeve is in the desired position, contacts an anatomical structure to position the sleeve relative to the target tissue.

1. A device for managing heating energy from a probe, the device comprising:
a sleeve sized and shaped for insertion into a vagina including a lumen sized to receive the probe therein, the sleeve defining a first window which, when the sleeve is in a desired position, faces target tissue to which the probe is to deliver energy; a shield element coupled to the sleeve and positioned, when the sleeve is in the desired position, to block a portion of the energy emitted from the probe to protect non-target tissue while permitting energy emanating from the surgical probe to pass to the target tissue, the shield element being formed of one of a material reflecting energy delivered by the probe and a material absorbing energy delivered by the probe, the shield element having a first protective element positioned to block energy emitted from the probe along a path extending to a urethra and a second protective element positioned to block energy emitted from the probe along a path extending to a bladder, the second protective element extending at an angle with respect to a longitudinal axis of the sleeve and with respect to the first protective element; and a positioning element coupled to the sleeve which, when the sleeve is in the desired position, contacts an anatomical structure to limit a depth of insertion of the sleeve to position the first window at a depth corresponding to the target tissue.
