1. A method for preparing a catheter for detecting a physiological parameter in a blood vessel, the method comprising:

  • providing a catheter assembly having;

    an elongated tube having a distal and proximal end, and a longitudinal axis extending between the distal and proximal ends, anda recess formed in an outer wall of the tube between the distal and proximal ends of the tube;

    positioning a sensing element for detecting the physiological parameter in the blood vessel into the recess, the sensing element comprising;

    a flexible substrate having first and second opposite surfaces;

    at least one sensor disposed on the first surface of the flexible substrate;

    an adhesive layer covering at least a portion of the second surface of the flexible substrate; and

    a release liner releasably adhered to the adhesive layer;

    removing the release liner to thereby expose the adhesive layer; and

    contacting the adhesive layer to a surface of the tube adjacent the recess to thereby secure the sensing element to the tube.
