摘要： An electrophysiologic catheter with an improved control handle is provided. The catheter includes a heat transfer assembly to better dissipate heat in the control handle. The heat transfer assembly includes a pump, a reservoir containing a coolant, a heat transfer member, and a coolant transport network transporting coolant between at least the reservoir and the heat transfer member. In one embodiment, the heat transfer member is located within the control handle as a heat exchanger on the circuit board to receive the coolant for transferring heat from the integrated circuits to the coolant. In another embodiment, the heat transfer member is located on the circuit board directly surrounding the integrated circuits to internally cool the integrated circuit within the control handle. A second heat transfer member is located outside of the control handle as a heat exchanger.

摘要： The present invention is directed to a catheter clamp that is affixable to a patient's skin to hold a catheter in position while in use within a patient's body. In one embodiment, the clamp has a base adapted to be removably adhered to the patient's skin, two clamp members supported on the base and defining a region therebetween to receive the catheter body, the clamp members being adapted to move between an open position and a closed position, and locking means for releasably locking said clamp members in said closed position to hold the catheter body in a generally fixed position relative to said clamp. In another embodiment, the clamp includes a base adapted to be removably adhered to the patient's skin, two clamp members supported on the base and defining a space therebetween to receive the catheter body, the clamp members being adapted to move between an open position and a closed position, and an elongated release tab extending between the two clamp members and configured to releasably lock the clamp member around the catheter body. The two clamp members may be pivotably coupled to each other and the tab may be pivotably attached on one of the clamp members.

摘要： A catheter has a three-dimensional, hollow ablation assembly that carries at least one ribbon electrode for circumferential ablation. In one embodiment, the assembly has a free-form framework that is constructed of multiple tensile members or wires that are interwoven such that the length of the framework increases while the circumference of the framework decreases, and vice versa. The assembly can also have a self-expanding stent-type framework which is mounted on the expander. In another alternative embodiment, the framework is a tubular or cylindrical structure whose side wall has longitudinal slots between longitudinal slats for radial expansion to a greater circumference when the length is decreased. The flexible ribbon electrode on the assembly is elastic, or is pleated so that it folds when the framework is collapsed and unfolds when the framework is deployed.
