    摘要: Methods and apparatus for sensing pressure are disclosed. One disclosed pressure measuring device comprises a pressure transmission catheter including a stem portion and a sheath fixed to the stem portion. The disclosed sheath comprises a wall defining a cavity that is in fluid communication with a stem lumen defined by the stem portion. The disclosed sheath has a first transverse extent and a second transverse extent that is different from the first transverse extent.

    摘要: A system includes a transceiver circuit to transceive at least a first analog signal and a digital signal. The system also includes a controller circuit, coupled to the transceiver circuit, to deliver at least one control signal thereto, the controller circuit including executable instructions defining a data frame for communication of the first analog signal and the digital signal, endpoints of the data frame defined by portions of successive first and second synchronization signals and defining a corresponding frame interval, the data frame including a first data band for transceiving a first data pulse therein. A relative position in time of the first data pulse represents the first analog signal, and a modulation of the frame interval represents the digital signal. The system further includes an analog signal interface circuit, coupled to the transceiver circuit, to provide at least the first analog signal representative of acquired data.
