Abstract
Abstract An apparatus coupled to a laser delivery device comprising a housing having a laser waveguide for receiving a laser beam from the delivery device and for transmitting the laser beam to an area of medical treatment and a connection for receiving radio frequency electrical current and transmitting the current to an electrode for providing the current to the area of medical treatment. The apparatus combines the advantages of radio frequency electrosurgery techniques and laser surgery techniques in one device, offering the surgeon instant access to both techniques during surgery, as needed.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
168 words
Apparatus adapted to be coupled to a laser beam delivery device comprising: a housing adapted to be coupled to the laser beam delivery device having means for receiving a laser beam from the delivery device and for transmitting the laser beam to an area of medical treatment; means disposed in the housing for receiving radio frequency electrical current and for transmitting the radio frequency electrical current to an applicator for providing the radio frequency electrical current to the area of medical treatment; and a waveguide attached to said housing comprising means for delivering the laser beam from said housing to the area of medical treatment and further comprising means for delivering the radio frequency electrical current along the waveguide to the area of medical treatment, said waveguide being adapted to be inserted into the lumen of an endoscope for insertion into a living being, the applicator being disposed at a distal end of said endoscope for supplying the radio frequency electrical current to the area of medical treatment.
