    Abstract: A catheter probe (501) is provided for introduction into a chamber of the heart having blood therein and formed by a wall through a lumen leading to the chamber. The catheter probe includes a flexible elongate tubular member (502) having proximal and distal extremities (502a, 502b) and a lumen (576) extending therebetween. A plurality of longitudinally-extending spaced-apart arms (511) having interconnected proximal and distal extremities (511a, 511b) are carried by the distal extremity of the flexible elongate tubular member. The arms are movable between a contracted position and an expanded position in which they bow outwardly from the longitudinal axis of the catheter probe. The arms subtend an angle of approximately 180 DEG or less about the longitudinal axis when in the expanded position. A plurality of longitudinally spaced-apart electrodes (512) are carried by each of the arms. Electrical conductors (541) extend through the elongate tubular member and are connected to the electrodes for performing electrical functions with respect to the electrodes. A wire (611) is slidably carried within the lumen for causing the arms to move to the expanded position. The electrodes carried by the arms can be urged against a portion of the wall of the heart when the arms are in the expanded position to map the portion of the wall.

    Abstract: In one embodiment, the present invention provides a wireless communication system for use with a blood pressure monitor system. The wireless communication system includes a portable unit that connects to a typical pressure transducer and a monitor interface unit that connects to a typical vital signs monitor. The portable unit obtains a pressure reading from the transducer by providing an excitation voltage to the transducer, then wirelessly transmitting the pressure data to the monitor interface unit. The monitor interface unit measures the excitation voltage supplied by the vital signs monitor to supply the pressure reading in a format recognizable by the vital signs monitor.
