    摘要： A surgical device includes an elongated shaft having first and second electrically isolated electrodes coupled to the shaft such that an exposed portion of the second electrode is disposed around only part of a circumference of the elongated shaft, and includes a portion that is spaced proximally from the first electrode. Another surgical device also includes an elongated shaft having first and second electrically isolated electrodes coupled to the shaft, wherein the shaft includes a first side, and exposed surfaces of the first and second electrodes are side-facing toward the first side. Various embodiments of a “cool back” are provided, allowing arthroscopic surgery on a first side of a device without tissue effects on a back side of the device.

    摘要： An apparatus for repairing a wound in soft tissue includes an introducer trocar with a sharpened distal end and a hollow lumen. An elongated pin has a distal end, a proximal end and a central section. The pin is formed of compacted, hydrophilic, cross-linked collagen and introduced into the hollow lumen in a non-deployed state. An advancement member includes a distal end and is at least partially positioned in the hollow lumen. The advancement member advances the elongated pin out of the introducer trocar distal end and into a soft tissue structure in the pin's non-deployed state and across a wound in the soft tissue structure. The pin becomes deployed to a deployed state when the collagen in the pin begins to hydrolyze, anchoring the pin and the wound so that the wound can be healed quickly. This produces a maintenance of position for two non-continuous bodies of soft tissue relative to each other. The non-continuity may be the result of a wound, laceration, cut or tear in contiguous soft tissue or at a location where approximation and joining of two discontinues soft tissue structures is desirable.

    摘要： This invention is directed to a system and method for partitioning a patient's heart chamber into a productive portion and a non-productive portion which are particularly suitable for treating patients with congestive heart failure. The partitioning system has a plurality of partitioning devices with reinforced, expandable membranes which separate the productive and non-productive portions of the heart chamber. When deployed within the patient's heart chamber, the second partitioning device is off-set from the deployed first partitioning device to cover a region of the wall defining the patient's heart chamber which is not covered by the first partitioning device. The multiple partitioning devices may be independent from each other or may be interconnected, e.g. a tether or strand.

    摘要： An apparatus for effecting change in at least a portion of a selected site of a collagen containing tissue that is at least partially adjacent to a fluid medium. The apparatus includes an energy delivery device configured to deliver a level of energy to the selected site of the collagen containing tissue. The energy delivery device includes a distal portion where a sensor is positioned. The sensor provides a signal indicative of the thermal energy content of at least the selected site of the collagen containing tissue and the adjacent fluid medium to a feedback control unit. The signal is received by the feedback control system which adjusts the level of energy supplied to the energy delivery.
