  • Patent number: 10973426
    Abstract: A catheter with basket-shaped electrode assembly with spines configured for hyper-flexing in a predetermined, predictable manner when a compressive force acts on the assembly from either its distal end or its proximal end. At least one spine has at least one region of greater (or hyper) flexibility that allows the electrode assembly to deform, for example, compress, for absorbing and dampening excessive force that may otherwise cause damage or injury to tissue wall in contact with the assembly, without compromising the structure and stiffness of the remaining regions of the spine, including its distal and proximal regions. The one or more regions of greater flexibility in the spine allow the spine to flex into a generally V-shape configuration or a generally U-shape configuration.

  • Patent number: 10925668
    Abstract: A catheter has a multifunctional “virtual” tip electrode with a porous substrate and a multitude of surface microelectrodes. The surface microelectrodes are in close proximity to each other and in a variety of configurations so as to sense tissue for highly localized intracardiac signal detection, and high density local electrograms and mapping. The porous substrate allows for flow of conductive fluid for ablating tissue. The surface microelectrodes can be formed via a metallization process that allows for any shape or size and close proximity, and the fluid “weeping” from the porous substrate provides more uniform irrigation in the form of a thin layer of saline. The delivery of RF power to the catheter tip is based on the principle of “virtual electrode,” where the conductive saline flowing through the porous tip acts as the electrical connection between the tip electrode and the heart surface.

  • Patent number: 10905347
    Abstract: An electrophysiology catheter with a distal electrode assembly having covered spine carrying a plurality of microelectrodes. The spines have nonconductive covers that are reinforced with tensile members, e.g., wires or fibers, that extend (or have portions that extend) longitudinally so as to minimize any elongation of the covers and the microelectrodes carried thereon. The tensile members may also have a length greater than the length of the spines so the proximal portions extend proximally from the spines, through the catheter and at least into the control handle for actuation by an operator for deflecting and moving the spines, like “fingers.

  • Patent number: 10898094
    Abstract: The present invention is directed to a physiological recording device and, more particularly, to a physiological recording device that can be used without skin preparation or the use of electrolytic gels. The invention is further directed to an encouragement ring which stabilizes and helps situate the physiological recording device on a subject's skin to help provide a better electrical signal, increase surface area, and reduce and minimize noise and artifacts during the process of recording or monitoring a physiological signal. The invention is still further directed to surface features on a surface of the physiological recording device with a size and shape that will not substantially bend or break, which limits the depth of application of the recording device, and/or anchors the recording device during normal application. The invention is even further directed to a method for manufacturing a physiological recording device, and minimizing cost of manufacture.
