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.

A medical diagnostic device comprising: (a) an elongate catheter having an elongate interior bore and an end for insertion into a living body; (b) a planar dielectric substrate attached to said catheter so as to protrude longitudinally outwardly from said interior bore at said end; (c) a plurality of electrical conductors mounted longitudinally on said dielectric substrate in a transversely spaced array protruding from said substrate in a direction normal to the plane thereof so as to define a longitudinal passageway between adjacent conductors, said array having an exterior end protruding longitudinally outwardly from said bore; (d) a pressure-sensing transducer having a pressure-sensing diaphragm with respective inner and outer sides, said transducer being mounted on said array of conductors so as to protrude longitudinally outwardly from said bore with said inner side of said diaphragm in communication with said passageway; and (e) means connecting said passageway with said bore and isolating said passageway from said outer side of said diaphragm.
