Intravascular heat exchange catheter and system with RFID coupling
First Claim
1. A system, comprising:
- a heat exchange catheter line assembly configured to convey working fluid circulating to and from at least one heat exchange element on an intravascular heat exchange catheter;
a heat exchange system configured for fluidly communicating with the heat exchange catheter line assembly to exchange heat with the working fluid, the heat exchange system including at least one processor;
a near field communication (NFC) member associated with the heat exchange system; and
an NFC element associated with the heat exchange catheter line assembly, wherein the NFC member is configured to provide the processor with a signal representative of whether the NFC member detects the NFC element, the processor being programmed to disable operation of the system responsive to a determination that a with heat exchange catheter line assembly that is not an assembly authorized for use with the heat exchange system has been attempted for use at least a predetermined number of times greater than one.

Abstract
A system includes a heat exchange catheter line assembly configured to convey working fluid circulating to and from at least one heat exchange element on an intravascular heat exchange catheter. The system also includes a heat exchange system that itself includes a processor and is configured for fluidly communicating with the heat exchange catheter line assembly to exchange heat with the working fluid. A near field communication (NFC) member associated with the heat exchange system and an NFC element associated with the heat exchange catheter line assembly are also included. The NFC member is configured to provide the processor with a signal representative of whether the NFC member detects the NFC element.

11. An apparatus, comprising:
- a heat exchange system
a first heat exchange catheter line assembly configured to convey working fluid circulating to and from at least one heat exchange element on an intravascular heat exchange catheter, the assembly also configured for fluidly communicating with the heat exchange system to exchange heat with the working fluid; and a near field communication (NFC) element associated with the first heat exchange catheter line assembly and configured to communicate with an NFC member associated with the heat exchange system; wherein the NFC element is configured to communicate with the NFC member to cause the NFC member to provide a processor on the heat exchange system with a signal indicating that the first heat exchange catheter line assembly is an assembly authorized for use with the heat exchange system, the processor being adapted to establish an operational state of the apparatus selected from one of; being disabled upon a determination by the processor that a heat exchange catheter line assembly that is not an assembly authorized for use with the heat exchange system has been attempted for use at least a predetermined number of times greater than one; being disabled upon a determination by the processor that a heat exchange catheter line assembly that is not an assembly authorized for use with the heat exchange system has been attempted for use at least a predetermined number of times without an intervening authorized use. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
