摘要： A method includes receiving multiple electrophysiological (EP) signals acquired by multiple electrodes of a multi-electrode catheter that are in contact with tissue in a region of a cardiac chamber, and respective tissue locations at which the electrodes acquired the EP signals. The region is divided into two sections. Using the EP signals acquired by the electrodes, local activation times (LAT) are calculated for the respective tissue locations, and found are: a first section of the two sections having a smaller average LAT value, and a second section of the two sections having a higher average value. Determined are a first representative location in the first section, and a second representative location in the second section. A propagation vector is calculated between the first and second representative locations, that is indicative of propagation of an EP wave that has generated the EP signals. The propagation vector is presented to a user.

摘要： Apparatus, including a tube having a proximal end, and a distal end for insertion into a body cavity including anatomical structures, and a blade mounted at the distal end. The apparatus also includes a handle at the proximal end and including a device which generates sensible outputs upon receiving activation signals, and a position sensor fixed in a predefined disposition relative to the tube. The apparatus additionally includes a processor configured to acquire an image of the cavity, to determine, in the image, locations for each of the structures, to receive, from the sensor, a position signal indicative of a blade location of the blade within the cavity, to determine, based on the blade location and the respective structure locations, a proximity of the blade to a given structure, and to convey, to the warning device, a given activation signal in response to the proximity to the given structure.

摘要： A medical device includes an insertion tube, having a longitudinal axis and having a distal end adapted for insertion through a body passage into a cavity within a body of a patient. An electrode is located on the distal end of the insertion tube and is configured to contact tissue in the cavity. A resilient member is contained within the distal end of the insertion tube and is configured, when unconstrained, to cause the distal end to bend away from the longitudinal axis in a curved shape and to straighten toward the longitudinal axis when subjected to a force.

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 is carried out using a probe having a distal conductive cap. At least one optical fiber is contained within the probe and terminates in proximity to an outer surface of the conductive cap. The optical fiber conveys optical radiation to the tissue while the power generator is activated and receives reflected optical radiation. An optical module measures the received reflected optical radiation, and a processor linked to the optical module analyzes the reflected optical radiation to determine impending steam pop events.

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： A method, including, while imaging a patient using an initial magnetic resonance imaging (MRI) sequence, generating an initial MRI reference signal in response to the initial MRI sequence using a reference sensor placed in proximity to the patient. The method further includes identifying, by locking on to the initial MRI reference signal, noise that will be generated in electrocardiograph (ECG) signals received from the patient, and computing a programmable correction to be applied to the ECG signals to reduce the noise. The method also includes applying the programmable correction to reduce the noise in the ECG signals, received from the patient, while imaging the patient using a subsequent MRI sequence and while locking on to a subsequent MRI reference signal generated in response to the subsequent MRI sequence using the reference sensor.
