    摘要: A method for transmitting control instructions to a sensor in a position tracking system includes generating a drive signal for driving a field generator. A control signal including the control instructions is superimposed on the drive signal. The field generator is driven with the drive signal, so as to generate a field to be sensed by the sensor. The field is detected at the sensor in order to determine position coordinates of the sensor and to demodulate the control signal so as to extract the control instructions. A functionality of the sensor is controlled based on the extracted control instructions.

    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: 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.

The measurements provided by the transducers indicate to the practitioner the position and orientation of syringe relative to the injection port. A console provides a visual indication of the relative position and orientation so as to guide the practitioner to insert the syringe at the proper site and in the proper direction and to penetrate the port cleanly and correctly.
