  • Patent number: 11324546
    Abstract: Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool. Thus, over a first cutting portion, radio frequency current may help cut the tissue and over a second or over transition region, the RF current may initiate vaporization of the fluid or other liquid to propel the tissue from the cutting device.

    Abstract: Study of intracardiac electrograms (IEGMs) during atrial fibrillation (AF) provides clinically significant information that can be used in ablation therapy. Methods include determining a regional feature, e.g., dominant frequency (RDF), which encompasses the relationship between simultaneously recorded electrodes and identifies the feature components of a region, rather than the feature of a single electrode. Methods employing the regional feature may be used to identify and characterize variation and disorganization in wavefront propagation or wave breaks (WBs) at each recording site, and may be used to direct catheter ablation therapy.

  • Patent number: 11213655
    Abstract: A medical device has a distal member with a configuration that can be changed by means of a control handle with a control assembly employing a rotational cam, a shaft, and a pulley, where the rotational cam is rotationally mounted on a portion of the control handle for rotation by a user. The rotational cam operates on the shaft to move it proximally or distally depending on the direction of rotation which in turn rotates the pulley to draw or release a puller wire to change the configuration of the distal member of the medical device. The shaft is oriented along a diameter of the control handle. The shaft has two ends which extends through two axial guide slots in the portion of the control handle to sit two opposing helical tracks formed on inner surface of the rotational cam. The guide slots are parallel with the longitudinal axis of the control handle and therefore maintain the shaft's diametrical orientation as the rotational cam is rotated to move the shaft proximally or distally.

The acquisitions are aggregated, to form a statistical distribution of the acquisitions as a function of estimated DOA and distance. Using a statistical test, it is checked whether the statistical distribution is consistent, in accordance with a predefined consistency criterion. If the statistical distribution is found consistent, an estimated location in the heart of a focal source of an arrhythmogenic activity that generated the received EP signals is derived from the statistical distribution.

  • Patent number: 10945626
    Abstract: An electrophysiology catheter with a distal electrode assembly having covered spine carrying a plurality of microelectrodes. The position of the microelectrodes on each spine is staggered relative to microelectrodes on adjacent spines so as to minimize the risk of electrodes on adjacent spines touching each other during use of the catheter. The staggered electrode configuration provides the distal electrode assembly with a greater effective contact surface because the effective concentric electrode arrays is increased or at least doubled.

  • Patent number: 10932851
    Abstract: Systems and methods for forming a lesion on an endocardial tissue of a patients heart involve placing an ablation assembly inside of the heart and adjacent to the endocardial tissue, and placing a guiding assembly outside of the heart. An ablation assembly includes an ablation element and a first attraction element, and a guiding assembly includes a second attraction element. First and second attraction elements can be attracted via magnetism. Techniques involve forming an ablation on the cardiac tissue of a patient's heart with an ablation element of the ablation assembly. Optionally, techniques may include moving the second attraction element of the guiding assembly relative to the patient's heart, so as to effect a corresponding movement of the ablation element of the ablation assembly.

  • 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.
