    摘要： Apparatus is provided for use with a steerable catheter that includes a thumb control adapted to control a deflection of a distal tip of the catheter. The apparatus includes a robot, including an end-effector, adapted to be coupled to the thumb control, and a controller, adapted to drive the end-effector to deflect the distal tip by manipulating the thumb control. The controller has an algorithm that uses an iterative process to direct the distal tip of the catheter to a desired position, responsive to six dimensions of location and orientation information position information

    摘要： Apparatus for controlling a steerable invasive probe having a handle. The apparatus includes a platform and a jig, which is mounted on the platform and is configured to receive the handle. The jig includes at least a first gear that is positioned and shaped to rotate the handle about an axis of the probe and a second gear that is positioned and shaped to operate a control on the handle for deflecting a tip of the probe. A drive module includes one or more motors. A transmission is coupled to the drive module and to the jig so as to controllably rotate at least the first and second gears and to translate the platform along a direction parallel to the axis in order to advance and retract the probe.

    摘要： A probe for insertion into the body of a subject includes a sensor, a first microcircuit, which stores first calibration data with respect to the sensor, and a first connector at the proximal end of the probe. A probe adapter includes a second connector, which mates with the first connector, a signal processing circuit, which is processes the sensor signal, and a second microcircuit, which stores second calibration data with respect to the signal processing circuit. A microcontroller in the adapter receives the first and second calibration data and computes combined calibration data. The adapter includes a third connector, which mates with a fourth connector on a console. The console includes signal analysis circuitry, which analyzes the processed signal using the combined calibration data provided by the probe adapter.

    摘要： A method for position sensing includes placing at a known position within a body of a subject a reference probe including at least one reference electrode. Electrical currents are passed through the body between the reference electrode and body surface electrodes. Characteristics of the electrical currents are measured and are used to generate an approximation of the known position of the reference probe. A correction factor is determined based on a relationship between the approximation and the known position. A target probe including at least one target electrode is placed within the body of the subject and second electrical currents are passed through the body between the target electrode and the body surface electrodes. Characteristics of the second electrical currents are measured and used to generate a calculated position of the target probe. The correction factor is applied to correct the calculated position.

    摘要： A position sensing system includes a probe adapted to be introduced into a body cavity of a subject. The probe includes a magnetic field transducer and at least one probe electrodes. 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.

    摘要： Methods and systems treat abnormal cardiac electrical activity employing a probe having first and second ablation electrodes disposed on a distal portion of the probe and a sensing electrode disposed between the first and second ablation electrodes, bringing the probe into contact with cardiac tissue, and applying energy through the first and second ablation electrodes to ablate target tissue along an ablation path, monitoring cardiac electrical activity using the sensing electrode to detect the cardiac electrical activity. After making an observation that the cardiac electrical activity is no longer detectable by the sensing electrode, energy application is terminated.
