Selective organ cooling catheter with guidewire apparatus and temperature-monitoring device
First Claim
1. A temperature monitoring device assembly comprising:
- an elongated catheter having a distal end and a proximal end, the catheter being configured for advancing the catheter into a patient, along a path defined by a guidewire, with the distal end located in the patient'"'"'s body and the proximal end located outside the patient'"'"'s body;
at least one temperature monitoring device located at or near the distal end of the guidewire generating respective at least one temperature signal, wherein the temperature monitoring device includes a device flange and extends beyond the distal end of the catheter until the device flange abuts a retaining flange on the catheter;
a catheter connector located at or near the proximal end of the catheter; and
a cable having a cable connector configured for engaging the catheter connector and at least one controller electrically connected to the cable connector.

Abstract
A guidable catheter for heating or cooling fluid in a feeding vessel in a vasculature of a patient includes a heat transfer element having exterior surface irregularities to create turbulence in a surrounding fluid. A supply catheter delivers a working fluid to an interior of the heat transfer element, and a return catheter returns a working fluid from the interior of the heat transfer element. A guidewire tube is provided adjacent one of the supply catheter or the return catheter and runs substantially parallel to the axis of the guidable catheter to receive a guidewire disposed within the guidewire tube. A temperature-monitoring device is disposed at the distal tip of the guidewire. Feedback is provided to control the temperature of a source of working fluid.

8. A method for controlling a heat exchanger, the method comprising the acts of:
-
inserting in a patient a catheter including a temperature sensor located near a distal end of the catheter, wherein the temperature sensor includes a sensor flange and extends beyond the distal end of the catheter until the sensor flange abuts a retaining flange on the catheter; receiving, from the temperature sensor, a temperature signal of the patient; controlling a heat exchanger for a cooling catheter in response to the temperature signal; and generating an alarm signal when the temperature signal reaches a predetermined value. - View Dependent Claims (9, 10, 11)
