ABSTRACT:
A parameter of blood is sensed in vivo with a system which includes a catheter and a probe. The catheter has a lumen extending therethrough, a proximal end, a distal end and a distal opening at the distal end. The probe includes one or more sensors at its distal end. A saline solution is introduced into the lumen so that there is an interface adjacent the distal opening of the catheter between the blood and saline solution. The probe is recieved within the catheter and affixed thereto. The interface is moved back and forth in the lumen to expose the sensors to blood so that they can sense the blood parameters of interest.
