    摘要: An apparatus for sterilizing a female patient in a transcervical procedure comprises an elongated catheter with a piezoelectric ultrasound transducer at its distal end. The catheter is inserted transcervically into the uterus and guided to the intramural region of a fallopian tube. The transducer is inserted into the intramural region in direct contact with the surrounding tissue. The transducer produces a radially dispersing acoustical wave front, heating the adjacent tissue and forming a thermal lesion therein. A fibrous tissue forms during the healing process, sealing the fallopian tube. An embodiment of the apparatus includes a movable thermal sensor for monitoring the tissue temperature at multiple locations along the lesion. Another embodiment of the apparatus includes a spring that centers the distal end of the catheter at the opening of the fallopian tube and provides a tactile means to determine that the catheter and transducer have been correctly positioned.

    摘要: A suture anchor and driver device is described that is designed to secure a suture anchor to a bone in a patient to allow soft tissue or the like to be secured to the bone. The suture anchor itself engages the suture along the length of a passage that passes through the diameter of the distal end of the suture anchor, providing for a relatively large area of engagement to minimize stress on the suture material. The driver is designed to engage the suture anchor and guide the suture material along outside surface of the driver.
