Claim:
1. A system, comprising: a catheter comprising a distal distension balloon and a plurality of circumferentially arranged motility measurement balloons proximal of the distension balloon; a manifold comprising: an elongated cylinder configured for rotation, wherein the cylinder includes an arrangement of bores contained therein; a plurality of balloon ports each configured to fluidly couple to one of the motility measurement balloons; a plurality of pressure transducer ports; and a priming port configured to open to atmospheric pressure or to receive a pressurized fluid; a port selector coupled to the manifold and rotatable between different positions, the manifold configured to rotate with the port selector so as to establish or prevent fluidic couplings among the balloon ports, the pressure transducer ports, and the priming port via the arrangement of bores in response to the different positions of the port selector; and a pressure sensing device comprising a plurality of pressure transducers each fluidly coupled to one of the plurality of pressure transducer ports, wherein the port selector and cylinder are configured to rotate so as to (a) permit the pressure transducers to be calibrated at the atmospheric pressure via the priming port with the port selector in a first position from among the different positions, (b) permit the motility measurement balloons to be primed via the pressurized fluid received by the priming port with the port selector in a second position from among the different positions, and (c) permit motility balloon pressure measurements to be performed by the plurality of pressure transducers via the balloon ports and the pressure transducer ports with the port selector in a third position from among the different positions, and wherein the priming port is fluidly decoupled from the balloon ports and the pressure transducer ports with the port selector in the third position.
