    摘要： An apparatus for treating disrupted articular cartilage comprising an elongate probe member having proximal and distal extremities and a handle coupled to the proximal extremity of the elongate probe member. The distal extremity has a peripheral wall defining a cavity and a distal opening communicating with the cavity. A controllable environment is created within the cavity when the distal extremity is placed substantially flush against the disrupted articular cartilage. An electrode is positioned within the cavity at a distance spaced inwardly of the distal opening. The disrupted articular cartilage is sealed to form a substantially continuous surface when energy is supplied to the electrode. A method of using the apparatus is provided.

    摘要： Disclosed herein is a new arthroscopic probe with a concave distal tip which simultaneously constrains and cuts tissue. It is particularly adapted to cutting ligaments and tendons. Also disclosed is a thermal energy delivery apparatus which includes (a) a probe means with a distal end and a proximal end, wherein the distal end has a concave tip; (b) a first electrode means positioned at the distal end of the probe means, wherein the first electrode means is configured to deliver sufficient thermal energy to cut ligaments or tendons; and (c) a cabling means coupled to the proximal end of the probe means.In another embodiment of the invention a controller for controlling the delivery of energy and liquid to a surgical instrument with a temperature sensor is disclosed. The energy is supplied by an energy source and the liquid is supplied by a pump. The controller includes a temperature and a flow regulator. The temperature regulator is coupled to the energy source and coupled to the pump. The temperature regulator is responsive to a first temperature indication from the temperature sensor to determine that the first temperature indication exceeds a setpoint and to reduce an energy level from the energy source. The flow regulator is coupled to the pump and coupled to the temperature regulator. The flow regulator includes responsiveness to the first temperature indication to increase a flow of the liquid from the pump.
