A catheter is disclosed comprising: a connector including a plurality of first contacts and one or more second contacts; a shaft including a plurality of electrodes, each electrode being coupled to a different one of the plurality of first contacts; a memory coupled to at least one of the second contacts, wherein the memory is configured to: store a pinout map identifying an order in which the plurality of electrodes is coupled to the plurality of first contacts; and provide the pinout map to an external device via one or more of the second contacts after the connector is coupled to the external device.

Random pinout catheter

A catheter for use with a suction source for removing excess fluid from a tissue treatment site has a catheter body, a distal section and a fluid evacuation path, where the distal section includes a multi-lumened member and at least one evacuation port, and the fluid evacuation path extends through a lumen in the multi-lumened member to provide suction communication between the suction source and the at least one evacuation port. The fluid evacuation path may also be configured for two-way flow, including distally and proximally along the catheter.

Irrigated multi-lumened electrophysiology catheter with fluid evacuation

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.

Catheter with liquid-cooled control handle

Irrigated catheter with fluid evacuation

A deflectable, catheter includes a catheter body, an intermediate section, a tip electrode and a control handle for deflecting the catheter by manipulation of a puller element that is made of a high modulus fiber material and extends through the catheter body and the intermediate section. The proximal end of the puller element is housed in the control handle and the distal end of the puller element is in a wrapped configuration and engages with a distal tip member or the intermediate section.

Deflectable catheter with a high modulus fiber puller element

A bi-directional electrophysiology catheter having improved steerability which includes orientation sheaths, or thin walled tubes, placed in diametrically opposed lumen at the distal portion of the catheter for producing in-plane deflection of the distal portion of the catheter.

Steerable catheter with distal tip orientation sheaths

An injection catheter for infusing therapeutic and diagnostic agents into the heart comprises a catheter body and a tip section mounted at the distal end of the catheter body. A needle control handle is provided at the proximal end of the catheter body. An injection needle extends through the tip section, catheter body, and needle control handle. The injection needle is longitudinally slidable within the tip section so that its distal end can extend beyond the distal end of the tip section upon suitable manipulation of the needle control handle. The catheter further comprises an electrode lead wire having a first end electrically connected to the injection needle and a second end electrically connected to a suitable monitoring apparatus or to a source of ablation energy. The injection needle can thus be used for mapping or ablation in addition to introducing therapeutic and diagnostic agents into the heart.

Injection catheter with needle electrode

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.

Catheter for circumferential ablation at or near a pulmonary vein

A deflectable catheter includes a catheter body, an intermediate section, a tip electrode and a control handle for deflecting the catheter by manipulation of a puller element that is made of a high modulus fiber material and extends through the catheter body and the intermediate section. The proximal end of the puller element is housed in the control handle and the distal end of the puller element is in a wrapped configuration and engages with a distal tip member or the intermediate section.
