  • Patent number: 10777318
    Abstract: An apparatus includes a network interface and a processor. The network interface is configured to communicate over a communication network. The processor is configured to receive (i) data, including a medical parameter acquired as a function of time, and (ii) a selection of one or more time intervals of interest within the time period. The processor is further configured to compress a first portion of the data, which is within the selected time intervals, at a first resolution, and compress a second portion of the data, which is outside the selected time intervals, at a second resolution, which is coarser than the first resolution. The processor is additionally configured to transmit the compressed first and second portions of the data, via the network interface, over the communication network.

  • Patent number: 10765475
    Abstract: Medical catheterization is carried out by introducing a catheter into a heart, sliding the catheter through a sheath that encloses a multi-electrode probe into a chamber of the heart. The sheath is retracted to expose the probe. As the sheath is retracted the exposed probe expands into a spiral configuration, and the electrodes contact the endocardial surface of the chamber at multiple contact points.

  • Publication number: 20200275972
    Abstract: A method of ablation includes storing in a memory a pre-determined relation between lesion size and amount of ablative energy, for each of one or more selected temperatures. Using a processor, user input is received, that indicates a lesion size and a tissue temperature. Based on the relation, an amount of energy is determined, that matches the lesion size and the tissue temperature. An ablation probe is controlled to apply the amount of ablative energy that matches the selected lesion size.

  • Patent number: 10743932
    Abstract: A catheter adapted for ablation has multiple dedicated irrigation tubings to supply fluid to their respective electrode or set of electrodes. The tubings provide parallel flow pathways through the catheter where irrigation fluid is delivered to irrigated tip and/or ring electrodes which can accomplish uni-polar or bi-polar ablation. Such separate and dedicated fluid pathways allow fluid to be delivered to the corresponding electrode or set of electrodes at different flow rates. An integrated ablation system using such catheter has an ablation energy source and an irrigation pump with multiple pump heads that can operate independently of each other. An integrated irrigation tubing set is included to extend between the fluid source and the catheter, with each pump head being able to act on a different tubing that delivers fluid to a different electrode or set of electrodes.

  • Publication number: 20200245896
    Abstract: Apparatus, including a magnetic tracking system, which generates a magnetic field near a living subject's body, and a probe, having a distal end that can contact registration points on a surface of the body. The probe has a contact sensor, located within the distal end, that outputs first signals indicative of a quality of the contact between the distal end with the registration points. Located within the distal end is a magnetic detector that outputs second signals that are indicative of respective positions of the registration points in a coordinate frame of the magnetic tracking system. A processor receives a tomographic image of the subject, and verifies, based on the quality of the contact indicated by the first signals, that the registration points are valid, and registers the tomographic image in the coordinate frame of the magnetic tracking system using the positions of the valid registration points.

  • Patent number: 10729485
    Abstract: 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.
