摘要： Ventricular tachycardia signals are induced in a living subject. Pace-mapped signals are then obtained from multiple points within the ventricle, and automatically compared numerically with the induced signals. Recognition of a high degree of cross correlation between the induced signals and one or more of the pace-mapped signals identifies arrhythmogenic foci or pathways, which may then be ablated, so that the arrhythmia becomes non-inducible.

摘要： An electrical connector includes one or more connector terminals, which are connected to wiring extending from the connector and are coupled to interconnect with corresponding connector terminals in a mating connector. An active shielding circuit is mounted adjacent to the connector terminals and is configured to sense a first magnetic field in a vicinity of the electrical connector and to generate, based on the sensed magnetic field, a second magnetic field that reduces interference induced in the wiring and the connector terminals by the first magnetic field.

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： Tissue ablation systems and methods are provided, wherein a cardiac catheter incorporates a pressure detector for sensing a mechanical force against the distal tip when engaging an ablation site. Responsively to the pressure detector, a controller computes an ablation volume according to relationships between the contact pressure against the site, the power output of an ablator, and the energy application time. A monitor displays a map of the heart which includes a visual indication of the computed ablation volume. The monitor may dynamically display the progress of the ablation by varying the visual indication.

摘要： A calibration apparatus includes a fixture, which is coupled to hold a distal end of a medical probe. A plurality of weights, which have respective masses and respective bottom surfaces that are oriented at respective angles with respect to the distal end of the probe, are coupled to rest on a distal tip of the probe so as to apply to the distal tip respective force vectors that cause a deformation of the distal tip relative to the distal end. A calibration processor is configured to receive from the probe measurements indicative of the deformation of the distal tip in response to the force vectors, and to compute, based on the measurements, the masses and the angles, calibration coefficients for assessing the force vectors as a function of the measurements.

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.
