Abstract: An ablation catheter includes a control handle and a catheter sheath removably connectable to the control handle, the catheter sheath defining a fluid lumen and having a plurality of perforations proximal the distal end of the catheter sheath. The ablation catheter further includes a shape-imparting element inserted into the fluid lumen of the catheter sheath and removably connectable to the control handle. The shape-imparting element is connectable to an RF energy source so that, in use, the shape-imparting elements act as an electrode charging fluid into the fluid lumen to be expelled through the plurality of perforations on the catheter sheath.

Abstract: A surgical instrument includes a housing, an energizable member, and a deployment mechanism. The deployment mechanism includes a one-way rotatable member, a linkage, and an actuator. The first end of the linkage is coupled to the one-way rotatable member at an offset position. The second end of the linkage is coupled to the energizable member such that a revolution of the one-way rotatable member moves the energizable member from the storage position to the deployed condition and back to the storage position. The actuator is selectively actuatable from an un-actuated state to an actuated state. Each actuation of the actuator effects a partial revolution of the one-way rotatable member such that each actuation of the actuator moves the energizable member from one of the storage position or the retracted position to the other of the storage position or the retracted positions.

Abstract: A surgical instrument includes a housing having a shaft extending distally therefrom, an end effector assembly disposed at a distal end of the shaft, a handle assembly coupled to the housing for manipulating the end effector assembly, a deployable assembly, at least one actuator for deploying and retracting the deployable assembly, and a closure member. The closure member is keyed to the actuator(s) and operably positioned relative to the movable handle of the handle assembly such that, upon rotation of the actuator(s) relative to the housing from an un-actuated position to an actuated position, the closure member is urged into contact with the movable handle to urge the movable handle from an initial position to a compressed position, thereby moving the end effector assembly to an approximated position.

Abstract: An electrosurgical scalpel for a gas-assisted electrosurgical system. The electrosurgical scalpel has a dielectric portion and a conductive portion. The dielectric portion forms a substantial majority of the outer surface of the scalpel such that the conductive portion is only exposed along a thin edge of the scalpel. The dielectric portion provided stiffness to the very thin conductive portion and causes energy to be concentrated at the thin edge of the scalpel.

Abstract: A fluid management system for use with a fluid reservoir includes an inflow pump and an outflow pump. The inflow pump is connectable to a probe for delivering a distention fluid to a body cavity. The outflow pump removes the distention fluid through the same probe, thus establishing a re-circulating volume of distention fluid within the body cavity. The removed fluid is filtered and returned to a fluid reservoir for eventual recycling to the body cavity. A controller adjusts the flow rates of the inflow pump and the outflow pump to maintain a pre-selected fluid pressure or volume within the body cavity.
