摘要： A method includes disposing multiple medical probes to acquire physiological data concurrently from a living body. The data is sent from the multiple medical probes by transmitting over wireless channels respective sequences of data packets that are marked with respective packet numbers. A synchronization signal that is broadcast to the multiple probes is received in the probes. In response to receiving the synchronization signal, the packet numbers that are to be assigned in the probes to subsequent data packets in the respective sequences are reset.

摘要： An apparatus includes detection circuitry and gating circuitry. The detection circuitry is configured to sense a radio frequency (RF) ablation signal that is applied to a heart by an intra-body probe, and to identify time intervals during which an amplitude of an ablation signal is within a predefined window. The gating circuitry is configured to gate an electrocardiogram (ECG) signal acquired in the heart, such that the ECG signal is sampled only within the identified time intervals.

摘要： A system is used for robotically controlling movement of a human-controllable catheter, wherein the catheter has at least one position sensor for generating or receiving signals used for determining six dimensions of location and orientation information. The system uses a robotic control mechanism and a computer for driving the robotic control mechanism to (i) translationally move the catheter distal end in a vicinity of a target, (ii) deflect the distal end of the catheter, and (iii) rotate the catheter. The computer determines roll of the catheter using six dimensions of location and orientation information based on signals generated or received from the at least one position sensor.

摘要： A calibration apparatus includes a fixture, which is coupled to accept a probe so that a distal tip of the probe presses against a point in the fixture and produces first measurements indicative of a deformation of the distal tip relative to a distal end of the probe, in response to pressure exerted on the distal tip. A sensing device is coupled to the fixture and is configured to produce second measurements of a mechanical force exerted by the distal tip against the point. A calibration processor is configured to receive the first measurements from the probe, to receive the second measurements from the sensing device and to compute, based on the first and second measurements, one or more calibration coefficients for assessing the pressure as a function of the first measurements.

摘要： In techniques for testing and calibrating an ablator, a tissue probe emulator is connectable to a tissue ablator being tested. The emulator includes a temperature sensor, a thermoelectric unit operative to vary a temperature sensed by the temperature sensor, an adjustable electrical load, electrical control circuitry connected to the thermoelectric unit and the electrical load and operative to independently adjust the electrical load and an output of the thermoelectric unit. The emulator conveys signals emitted by the temperature sensor to the tissue ablator and conveys an ablation energy output of the tissue ablator to the electrical load.
