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： An introducer has a shaft with a central lumen, a control handle with a deflection assembly, and a tensile member with a distal portion extending along opposing sides of within the shaft and a proximal portion extending within the control handle. The deflection assembly has a deflection arm, and a rotatable member rotationally coupled to the deflection arm, wherein the rocker member has at least one pulley engaged with the proximal tensile member portion. Rotation of the deflection arm in one direction draws the proximal tensile member portion for deflecting the shaft.

摘要： A medical device has a distal member with a configuration that can be changed by means of a control handle with a control assembly employing a rotational cam, a shaft, and a pulley, where the rotational cam is rotationally mounted on a portion of the control handle for rotation by a user. The rotational cam operates on the shaft to move it proximally or distally depending on the direction of rotation which in turn rotates the pulley to draw or release a puller wire to change the configuration of the distal member of the medical device. The shaft is oriented along a diameter of the control handle. The shaft has two ends which extends through two axial guide slots in the portion of the control handle to sit two opposing helical tracks formed on inner surface of the rotational cam. The guide slots are parallel with the longitudinal axis of the control handle and therefore maintain the shaft's diametrical orientation as the rotational cam is rotated to move the shaft proximally or distally. Actuation of the puller wire by means of the control assembly can result in a change of the distal member's configuration, including deflection, contraction and/or expansion.

摘要： A patch and sensor assembly has a biosensor housed in a reusable portion that connects to a mapping and localization system (MLS) via biosensor wires. A disposable portion has an electrode layer through which signals are transmitted to the MLS via ACL wires. The biosensor and ACL wires extend through a single cable exiting the reusable portion. The disposable portion includes an adhesive layer for adhering the electrode layer to a patient, on the electrode layer, and an engagement element for detachably receiving at least a portion of the housing of the reusable portion. The reusable portion includes a housing in which the biosensor has biosensor wires that exit the reusable portion. The housing is also adapted to carry and/or provide support to an ACL contact member responsive to the electrode layer of the disposable portion, and ACL wires that exit the reusable portion.
