摘要： Medical apparatus includes an electrical power supply, which is configured for connection to an electrical medical device that is coupled to a body of a patient. In one embodiment, the apparatus includes alternating current (AC) lines that include a ground line. A switch is coupled to connect and disconnect the AC lines from an AC power source. A current sensor is coupled to sense a current flowing in the ground line and to actuate the switch to disconnect the AC lines when the current exceeds a predetermined threshold. In another embodiment, a plurality of electrocardiogram (ECG) leads, including a common lead, are coupled to the body of the patient. An auxiliary current sensor is coupled to monitor a current flowing through the common lead and to actuate the switch to disconnect the power connection when the current exceeds a predetermined limit.

摘要： Body tissue ablation is carried out by inserting a probe into a body of a living subject, urging the probe into contact with a tissue in the body, generating energy at a power output level, and transmitting the generated energy into the tissue via the probe. While transmitting the generated energy the ablation is further carried out by determining a measured temperature of the tissue and a measured power level of the transmitted energy, and controlling the power output level responsively to a function of the measured temperature and the measured power level. Related apparatus for carrying out the ablation is also described.

摘要： A method for contact sensing includes transmitting optical radiation from an optical emitter coupled to a distal tip of medical probe that is positioned within a body cavity. A signal, which is indicative of a reflection of the optical radiation from tissue in the body cavity, is received from an optical detector coupled to the distal tip.

摘要： A method for tracking an object includes fixing to the object a transmitter for transmitting a position-indicative magnetic field and providing a map of distortion of the position-indicative magnetic field caused by the object. A distorted magnetic field transmitted from the object is sensed. The distorted magnetic field includes the position-indicative magnetic field subject to the distortion caused by the object. Estimated coordinates of the object based on the sensed, distorted magnetic field are determined. The estimated coordinates and the map are used to compute corrected coordinates.

摘要： A calibration apparatus includes a fixture coupled to hold a distal end of a medical probe. An actuator is configured to press against the distal tip of the probe and apply to the distal tip multiple force vectors having respective magnitudes and angles with respect to the distal end, so as to cause a deformation of the distal tip relative to the distal end. A sensing device is configured to measure the magnitudes of the force vectors applied by the actuator. A calibration processor is configured to receive from the probe first measurements indicative of the deformation of the distal tip in response to the force vectors, to receive from the sensing device second measurements indicative of the magnitudes of the force vectors, and to compute, based on the angles and the first and second measurements, calibration coefficients for assessing the force vectors as a function of the first measurements.

摘要： A position sensing system includes a probe adapted to be introduced into a body cavity of a subject. The lasso-shaped probe includes a magnetic field transducer in the rigid section proximal to the flexible lasso-shaped distal section which has at least one probe electrode. A control unit is configured to measure position coordinates of the probe using the magnetic field transducer. The control unit also measures an impedance between the at least one probe electrodes and one or more points on a body surface of the subject. Using the measured position coordinates, the control unit calibrates the measured impedance and provides an indication of the deformation and deflection of the flexible lasso-shaped distal section in relation to the magnetic field transducer in the rigid proximal section.

摘要： A medical probe includes a flexible insertion tube, having a distal end for insertion into a body cavity of a patient, and a distal tip, which is disposed at the distal end of the insertion tube and is configured to be brought into contact with tissue in the body cavity. A resilient member couples the distal tip to the distal end of the insertion tube and is configured to deform in response to pressure exerted on the distal tip when the distal tip engages the tissue. A position sensor within the probe senses a position of the distal tip relative to the distal end of the insertion tube, which changes in response to deformation of the resilient member.
