    摘要： A cryoablation system including a cannula having a proximal end, a distal end, and a longitudinal axis, an expandable balloon extending from the distal end of the cannula and fluidly connected to a source of heat transfer fluid by at least one fluid path, a pump for circulating the heat transfer fluid into and out of the balloon, a probe handle coupled to the proximal end of the cannula and in fluidic communication with the balloon through the cannula, and a heat exchanger for varying the temperature of the heat transfer fluid, wherein the heat exchanger is fluidly connected to a secondary refrigerant source. The heat exchanger may be positioned within the probe handle, within the cannula, or at least partially within the balloon. The heat transfer fluid of this cryoablation system preferably has a freezing point lower than about −110° C. and a boiling point greater than about 50° C.

    摘要： A medical device is provided and includes a thermal ablation catheter and a deployable cage assembly for use in thermal ablation therapy. The deployable cage assembly includes a plurality of arms, each of which has a pair of opposed ends attached to the thermal ablation catheter. Each of the arms is movable from a relaxed configuration to a deployed configuration. When relaxed, the arms are substantially proximate to the thermal ablation catheter. When deployed, the arms cooperate with each other to form an open structure which extends radially outward from the thermal ablation catheter. The thermal ablation device also includes a distensible bladder that serves as an endocervical seal.

    摘要： A malleable shaft device for use in surgical procedures, having a tension fiber therein, whereby the malleable shaft transitions from a malleable state to a rigid state when a force is applied to the tension fiber, has a variable-pitch cam operatively connected to the tension fiber, and a lever operatively connected to the variable pitch cam for applying force. The mechanical advantage of the cam changes with displacement to accommodate increasing load, and to increase the rate of travel while loads are light. The force profile may provide for a constant input force to accomplish the full travel of the cam.
