Abstract
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.
