ABSTRACT:
Apparatus and method for positioning a probe through a catheter wherein a sensing element on the probe is located outside the catheter but is spaced from the luminal surface of the blood vessel to prevent any adverse effect on the sensor measurement. A standard introducer catheter may be used and a support tube is provided around a portion of the probe and is slidably engagable within the catheter lumen for positioning the probe against an anterior wall of the catheter, away from a posterior vessel wall on which the catheter lies. In a second embodiment, a portion of the support tube extends outside the distal end of the catheter to prevent any possible contact between the sensing element and posterior vessel wall.
