摘要： Systems and methods presented herein generally include a catheter with a basket assembly at a distal tip having an atraumatic structure on a distal portion of the basket assembly and a distal sensor coupled to the atraumatic structure. The basket assembly includes spines that collapse for delivery through a delivery sheath catheter and self-expand upon exiting a distal end of the delivery sheath catheter. The basket assembly can further include a proximal sensor coupled to a shaft of the catheter, and position signals from the shaft sensor and the distal sensor can be used to determine position of electrodes of the basket assembly when the basket assembly is pressed to tissue or another surface.

摘要： A catheter includes a shaft for insertion into an organ of a patient, and an expandable distal-end assembly, which is coupled to the shaft and to an apex of the catheter, and includes multiple splines. In at least a given spline among the multiple splines, at least sixty percent of a length of the given spline is non-insulated and is configured to make contact with tissue of the organ and to apply radiofrequency (RF) pulses to the tissue.

摘要： A system includes a catheter and an IRE pulse generator. The catheter includes an expandable frame fitted at a distal end thereof, the expandable frame including multiple electrodes configured to be placed in contact with a tissue in an organ of a patient, wherein a lateral distance between neighboring edges of any pair of adjacent electrodes is uniform along a longitudinal axis, and wherein the electrodes are configured to apply irreversible electroporation (IRE) pulses to tissue between pairs of the electrodes. The IRE pulse generator is configured to generate the IRE pulses.

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.
