摘要： Apparatus for medical treatment, consisting of a probe and a processor. The probe has an insertion tube having a distal end configured for insertion into a body cavity of a living subject, and a basket assembly having multiple resilient spines coupled to the distal end of the insertion tube and joined together in a predefined form when the basket assembly is unconstrained by external forces. The probe also has a force sensor configured to output an indication of a force exerted on the basket assembly within the body cavity. The processor is configured to receive the indication of the force, to compute a constrained form of the basket assembly, different from the predefined form, responsively to the force, and to render to a display a graphical image representing the constrained form of the basket assembly.

摘要： The disclosed technology includes electrode for a medical probe, including an electrode body configured to deliver electrical energy to biological tissues, and one or more legs attached to the electrode body and configured to bend at least partially around or into a spine of a basket catheter so as to be attached thereto. The one or more legs can extend from an edge of the electrode body and can be configured to be bent such that the electrode is crimped to the spine.

摘要： A catheter apparatus includes an elongated deflectable element including a distal end, a coupler connected to the distal end, a pusher including a distal portion, and configured to be advanced and retracted through the deflectable element, and an expandable assembly including flexible polymer circuit strips, each strip including electrodes disposed thereon. The strips can be configured to bow radially outward when the pusher is retracted expanding the expandable assembly from a collapsed form to an expanded form. A covering can at least partially enclose the flexible polymer circuit strip and the multiple electrodes. The covering can include a plurality of apertures at each electrode so that a portion of the conductive surface of each electrode is exposed through each aperture.

摘要： A system for use with multiple electrodes coupled to respective spines of a probe includes multiple switches connected to the electrodes and configured to short different respective first subsets of the electrodes to each other and different respective second subsets of the electrodes to each other per different respective settings of the switches. The system further includes a processor configured to control the switches so as to alternate through the settings and, for each of the settings, cause a power generator to apply a voltage between the shorted first subset and the shorted second subset while the probe is deployed within a body of a subject. Other examples are also described.

摘要： A catheter includes a shaft for insertion into an organ of a patient, an expandable distal-end assembly, and at least an electrical interconnection. The expandable distal-end assembly is coupled to the shaft and includes multiple splines, at least one of the splines includes a flexible substrate, which is configured to conform to tissue of the organ. The electrical interconnection has: (i) a first section, which is formed within the flexible substrate and is configured to conduct ablation signals, and (ii) a second section thicker than the first section, which is formed over an outer surface of the flexible substrate and is configured to apply the ablation signals to the tissue.
