Abstract
A compact catheter assembly provides for the communication of a reference pressure to a pressure-sensing transducer by forming a passageway between spaced electrical conductors mounted on a planar dielectric substrate. The cathter assembly also provides for the operative mounting of multiple transducers onto a single catheter tip by employing a plurality of planar dielectric substrates, each having an array of electrical conductors, stacked atop one another so as to protrude longitudinally from the end of the catheter bore at different distances. A plurality of electrical transducers protrude longitudinally in series from the bore overlying the substrates.
