  • Patent number: 7803155
    Abstract: An embodiment of the invention includes a surgical device for coagulating soft tissue such as atrial tissue in the treatment of atrial fibrillation, atrial flutter, and atrial tachycardia; tendon or ligament shrinkage; or articular cartilage removal. The surgical device integrates a suction mechanism with the coagulation mechanism improving the lesion creation capabilities of the device. The surgical device comprises an elongate member having an insulative covering attached about conductive elements capable of coagulating soft tissue when radiofrequency or direct current energy is transmitted to the conductive elements. Openings through the insulative covering expose regions of the conductive elements and are coupled to lumens in the elongate member which are routed to a vacuum source. Suction causes the soft tissue to actively engage the opening thus the integrated, exposed conductive elements to facilitate the coagulation process and ensure the lesions created are consistent, continuous, and transmural.

  • Patent number: 7780656
    Abstract: A spray of cryogen is patterned to create a pattern of cooled regions on a target tissue for cosmetic dermatological treatment. In one embodiment, the cryogen is patterned using a heated mask. An optical source is configured to irradiate the target tissue in a region at least partially overlapping the cooled regions to create a pattern of treatment zones. A control unit adjusts the timing of between the cryogen and optical pulses.
