摘要：
A system having a catheter having a distal pressure sensitive capacitive element providing an impedance and phase shift which varies responsive to the amount of pressure from blood external the catheter, a detector having electronics for determining the impedance and/or phase shift. This impedance and or phase shift corresponds to the pressure of the blood about the distal end of the catheter. When the catheter is inserted into a patients body, the impedance or phase shift is detected quasi wirelessly without special signal communication means like optical fibers or electrical wires from outside the patients body utilizing the patient as a ground path and the catheter shaft as an electrical conductor.
