    摘要: A method for position tracking includes placing an internal reference probe in a reference location within a heart of a subject, and collecting and processing first location coordinates of the internal reference probe during one or more respiratory cycles so as to define a range of the location coordinates corresponding to the reference location. An active device is inserted into the heart, and second location coordinates of the active device are collected. The first and second location coordinates are jointly processed so as to find relative location coordinates of the active device in a cardiac frame of reference. When a deviation of the first location coordinates from the range is detected, the relative location coordinates are corrected to compensate for displacement of the reference probe from the reference location.

    摘要: An inventive system and method for touch free operation of a device is presented. The system can comprise a depth sensor for detecting a movement, motion software to receive the detected movement from the depth sensor, deduce a gesture based on the detected movement, and filter the gesture to accept an applicable gesture, and client software to receive the applicable gesture at a client computer for performing a task in accordance with client logic based on the applicable gesture. The client can be a mapping device and the task can be one of various mapping operations. The system can also comprise hardware for making the detected movement an applicable gesture. The system can also comprise voice recognition providing voice input for enabling the client to perform the task based on the voice input in conjunction with the applicable gesture. The applicable gesture can be a movement authorized using facial recognition.

    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.
