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： A catheter adapted for ablation has multiple dedicated irrigation tubings to supply fluid to their respective electrode or set of electrodes. The tubings provide parallel flow pathways through the catheter where irrigation fluid is delivered to irrigated tip and/or ring electrodes which can accomplish uni-polar or bi-polar ablation. Such separate and dedicated fluid pathways allow fluid to be delivered to the corresponding electrode or set of electrodes at different flow rates. An integrated ablation system using such catheter has an ablation energy source and an irrigation pump with multiple pump heads that can operate independently of each other. An integrated irrigation tubing set is included to extend between the fluid source and the catheter, with each pump head being able to act on a different tubing that delivers fluid to a different electrode or set of electrodes.

摘要： A catheter has a distal section that includes a spring member having at least a slot, a rib and a spine for biasing the distal section for deflection within a single plane. Depending on the plurality and orientation of slot(s), rib(s) and spine(s)s, the distal section can allow for deflection in two opposing directions while allowing only limited deflection in perpendicular directions to maintain torquability, axial loading capabilities, and side force performance.

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 foam layer 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.

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 device that shields internal organs and tissues from medical procedures performed within a patient's body, especially in the chest cavity where ablation and related procedures are performed in or near the heart, includes a catheter body, a distal section, and a barrier member that can be inflated with fluid to act as a barrier to extreme temperatures and physical trauma, and be deflated to a smaller size to facilitate entry and removal from the patient's chest cavity. In a more detailed embodiment, the barrier member is a balloon that can protect the esophagus, which can be provided with folds and shape memory elements so that the balloon expands and collapses into predetermined configurations. Fluid is fed to and drawn from the barrier member via an irrigation tubing that extends along a catheter shaft and is in communication with a lumen of a deflectable tubing section that extends through an interior cavity of the barrier member. The catheter can be adapted for uni- or bi-directional deflection.

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.
