Abstract

An introducer sheath/temperature probe assembly that is insertable into a blood vessel of a human or veterinary patent to measure the temperature of blood flowing through that blood vessel. The introducer sheath/temperature probe assembly may be used in conjunction with an indwelling heat exchange catheter system to warm or cool all or a portion of the patient'"'"'s body to a desired target temperature and to maintain such target temperature for a desired period of time.

Claims

1. An introducer sheath/temperature probe assembly comprising:

a tubular introducer sheath having a proximal end, a distal end and a lumen which extends longitudinally therethrough, said introducer sheath being insertable into a blood vessel; and

,

an elongate temperature probe having a distal end and a proximal end, said temperature measuring probe being insertable distal end first into the lumen of the introducer sheath and useable, when inserted into the lumen of the introducer sheath, to sense the temperature of blood flowing through the blood vessel into which the introducer sheath is inserted.
