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:
a plurality of motility 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 an atmospheric pressure or to receive a pressurized fluid;
a port selector coupled to the manifold and movable between different port selector positions comprising a first position, a second position, and a third position, each of the different port selector positions causing the manifold to establish or prevent different fluidic couplings among the motility balloon ports, the pressure transducer ports, and the priming port; and
a pressure sensing device comprising a plurality of pressure transducers each fluidly coupled to one of the plurality of pressure transducer ports, the pressure sensing device configured to coordinate calibration of the pressure transducers at the atmospheric pressure via the priming port with the port selector in the first position and coordinate motility balloon pressure measurements via the motility balloon ports and the pressure transducer ports with the port selector in the third position, wherein the manifold is configured to fluidly decouple the priming port from the motility balloon ports and the pressure transducer ports with the port selector in the third position.
