Abstract: An ablation catheter with an expandable balloon or a basket, a plurality of electrodes disposed on the surface, and a graphical user interface (GUI) of a computer system is disclosed. The GUI includes a plurality of electrode representations, a first sector color coded plot of at least one of the plurality of electrodes, a second sector color coded plot of at least one of the plurality of electrodes, a third sector color coded plot of at least one of the plurality of electrodes, and a processor configured to receive data on the inputs based on at least one of the plurality of electrodes, change an appearance of at least one of the first, second sector, and the third sector based on the received data, and update the color coded plot of the first input.

Abstract: The subject of this disclosure includes an apparatus for visually supporting a tissue ablation procedure, including a display comprising a user interface; and at least one processor in communication with the display, the at least one processor configured to control one or more of a plurality of electrodes of a radiofrequency balloon catheter to ablate organ tissues of one or more targeted pulmonary veins; determine a characteristic, based on ablation parameters of the radiofrequency balloon catheter, of pulmonary vein isolation (PVI) success rate; and present, on the display, visual information corresponding to each electrode for an indication, based on the characteristic, for PVI success rate.

Abstract: A system, device and method for left atrial appendage occlusion detection is disclosed. The system for occlusion detection comprises a sheath; a delivery system comprising: a delivery catheter extending between a proximal end and a distal end; and a handle coupled to the proximal end of the delivery catheter; a medical tool coupled to a distal end of the delivery catheter at a target location within a portion of an organ of a patient, the medical device comprising a hub including a bore defining an axis, an occluder portion coupled to the hub and an anchor portion extending between a first end and a second end; at least one pressure sensor configured to measure a pressure of the target cavity while blood is suctioned form inside the left atrial appendage; and at least one processor configured to process the pressure measurement acquired from the at least one pressure sensor.

Abstract: A method of occlusion detection is disclosed. The method comprises the steps of positioning a medical tool coupled to a distal portion of a distal end of a delivery catheter at a target cavity within a patient. The medical tool includes an expandable balloon, and at least one sensor. The expandable balloon is expanded when positioned at the target cavity. The expandable balloon includes a membrane formed of a plurality of irrigation pores. Fluid is introduced into the target cavity either by injection or through the pores, or both. Using a sensor, a characteristic of blood is detected with the target cavity. The characteristic of blood is processed to determine the presence or absence of an occlusion within the cavity.

Abstract: The subject of this disclosure includes systems, devices and methods to treat a predetermined patient population for paroxysmal atrial fibrillation, the method including ablating tissue of one or more targeted pulmonary veins with one or more of a plurality of the electrodes of an independently controlled multi-electrode radiofrequency balloon catheter, the balloon catheter comprising the plurality of electrodes for radiofrequency ablation that are independently controllable; determining a predictor, based on ablation parameters of the balloon catheter, of single shot pulmonary vein isolation (PVI) success rate; and achieving, based on the predictor and step of ablating tissue, a single shot isolation PVI success rate in the isolation of all targeted pulmonary veins for the predetermined patient population.

Abstract: Apparatus for calibration includes a mount and one or more acoustic targets. The mount, which is adapted to hold a medical probe, includes an acoustic imaging device that emits ultrasonic beam in a plane, while permitting an orientation of the plane of the ultrasonic beam to be adjusted. The one or more acoustic targets are arranged to continuously intersect the plane of the ultrasonic beam over a given range of orientation angles.
