ABSTRACT:
A temperature monitoring catheter which has an elongated shaft having a distal end and a proximal end and a wall portion defining a drainage lumen extending longitudinally therethrough. The wall portion can also define a longitudinally extending inflation lumen which extends therethrough. The drainage lumen opens at the proximal end of the shaft through a drainage eyelet. An elastic, inflatable sleeve portion can be bonded to and extend annularly around a portion of the proximal end of the shaft. The elastic, inflatable sleeve portion is in fluid communication with the inflation lumen so that it can be inflated for retaining the catheter in a patient's body. A temperature thermistor is imbedded in the wall of the shaft at the proximal end of the shaft. A bifilar electric wire coil, helically wound, is imbedded in the wall of the shaft and connected at one end to the temperature thermistor. The other end of the bifilar wire extends from the distal end of the shaft for providing a connection to a power source and to a temperature monitor.
