    Abstract: A catheter includes a shaft for insertion into an organ of a patient, an expandable distal-end assembly, and one or more electrodes. The expandable distal-end assembly 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. The one or more electrodes are coupled to at least one of (i) an insulated section of one or more of the splines, and (ii) the apex, and, when placed in contact with the tissue, the one or more electrodes are configured to sense electrical signals in the tissue.

  • Patent number: 11938317
    Abstract: Energy is transmitted to a body lumen or passageway in the form of pulsed electric fields (PEFs) and in a manner which provides focal therapy. In some embodiments, PEFs are delivered through independent electrically active electrodes of an energy delivery body, typically in a monopolar fashion. Such delivery concentrates the electrical energy over a smaller surface area, resulting in stronger effects than delivery through an electrode extending circumferentially around the lumen or passageway. It also forces the electrical energy to be delivered in a staged regional approach, mitigating the effect of preferential current pathways through the surrounding tissue. Focal delivery of PEFs can provide increased tissue lethality by employing precise timing and sequencing of energy delivery to the electrodes.

  • Patent number: 11937945
    Abstract: An electrophysiology catheter has a micro capacitive tactile sensor provided in the distal section. The distal section may include a tip electrode, a ring electrode and/or a balloon catheter adapted for tissue contact. The capacitive force sensor is configured to exhibit a change in capacitance with tissue contact wherein the force applied with tissue contact is measured and reliably calibrated in assessing and determining the applied force. The capacitive force sensor has a first plate affixed to a tissue contact portion of the catheter, a second plate configured for contact with the tissue, and an elastically compressible dielectric between the first and second plates, wherein the force sensor has a first capacitance when the first and second plates are separated by a first distance, and the force sensor has a second capacitance when the first and second plates are separated by a second different from the first distance.
