    Abstract: A system for controlling deployment of an implantable medical includes an implantable medical device and a gripper mechanism. One or both of the medical device and the gripper mechanism are made from a shape-memory alloy material having a temperature at which the material will transition from a martensite state to an austenite state. The shape-memory alloy material has a transition temperature that is higher than a normal body temperature and a wide hysteresis band, with a temperature at which the material transitions back into the martensite state being below a normal body temperature. The medical device will expand or change shape upon being heated by a current passing therethrough, but will not transition into its remembered shape until such current is applied.

    Abstract: RF ablation apparatus includes an anode electrode assembly including an anode terminal housed within a catheter. The catheter includes a distal end wall which is disposed in a plane substantially perpendicular to the longitudinal dimension of the catheter. The anode electrode is slidably received within the cathode and can be extended out beyond the distal end of the catheter to provide at least a first terminal for an ablation circuit. The distal end wall is sized and shaped to hold a thrombus formed on the anode electrode so that the anode electrode can be withdrawn from within the thrombus formation and into the catheter, without the thrombus formation being pulled with the anode terminal. The outer surface of the catheter, or at least at the distal end thereof, is made of an insulating or non-conducting material, such that a thrombus does not form over the catheter. The assembly allows for the generation of a thrombus to occlude a vessel and without the risk of pulling any formed thrombus with the apparatus upon retrieval of the apparatus from the patient.
