ABSTRACT:
A pressure sensor probe is disclosed whose pressure interface forms the extreme end of a balloon type cardiac assistance device, hydraulic interface usually being provided to feed the pressure within a patient's aorta back to a sensor outside the patient. A small tube provides the inter-connection between the interface of blood and sensing solution and the sensor which tube enters the tubular conduit used to feed pneumatic pressure to the balloon at an intermediate position thereof and extends therethrough toward the patient.
