Publication number: 20180078173Abstract: A medical device can be localized by providing at least three non-colinear localization elements (e.g., electrodes) thereon. Once placed in a non-ionizing localization field, three adjacent localization elements, at least one of which will typically be a spot electrode, may be selected, and the non-ionizing localization field may be used to measure their locations. A cylinder is defined to fit the measured locations of the selected localization elements. The cylinder is rotationally oriented using the measured location of a spot electrode. Location and rotational attitude information may be used to construct a three-dimensional representation of the medical device within the localization field. The electrodes may be provided on the medical device or on a sheath into which the medical device is inserted. The invention also provides systems and methods for identifying and calibrating deflection planes where the medical device and/or sheath are deflectable.Type: ApplicationFiled: October 4, 2017Publication date: March 22, 2018Inventors: John Anderson Hauck, Lubomir Velitchkov Dragnev, Don Curtis Deno, Eric John Wilkowske

Patent number: 9901271Abstract: A method of generating a cardiac electrophysiology map includes receiving a reference biological signal and an electrical signal indicative of electrical activity at a location on a patient's heart. Using a graphical user interface, a practitioner designates at least two trigger point icons, one upward-pointing and one downward-pointing, on a graphical representation of the reference biological signal (e.g., a waveform). By pairing one upward-pointing icon with one downward-pointing icon, a plurality of triggering criteria are defined. Electrophysiology data points are captured and/or added to the electrophysiology map when the triggering criteria are satisfied.Type: GrantFiled: June 26, 2017Date of Patent: February 27, 2018Assignee: St. Jude Medical, Cardiology Division, Inc.Inventor: Don Curtis Deno

Publication number: 20160095642Abstract: A system and method for assessing a degree of coupling between an electrode and tissue in a body is provided. Values for first and second components of a complex impedance (e.g., resistance and reactance or impedance magnitude and phase angle) between the electrode and the tissue are obtained. These values are used together with a standardization value indicative of a deviation from a reference standard by a parameter associated with at least one of the body, the electrode and another component of the system to calculate a coupling index that is indicative of a degree of coupling between the electrode and the tissue. The coupling index may be displayed to a clinician in a variety of ways to indicate the degree of coupling to the clinician. The system and method find particular application in ablation of tissue by permitting a clinician to create lesions in the tissue more effectively and safely.Type: ApplicationFiled: October 8, 2015Publication date: April 7, 2016Inventors: Don Curtis Deno, Stephan P.

Patent number: 9220435Abstract: A method of mapping cardiac electrical activity includes the acquisition of electrophysiological signals and using signal processing hardware to process such signals to identify lateness attributes thereof. If the lateness attribute exceeds a lateness threshold, then the corresponding point on the patient's heart can be designated as a therapy (e.g., ablation) target. It is also contemplated to use an upper bound on the lateness threshold, such that the corresponding point on the patient's heart is only designated as a therapy target if the lateness attribute both exceeds the lateness threshold and does not exceed the lateness bound. Both late activation (“Late-A”) and late potential (“Late-P”) attributes are contemplated.Type: GrantFiled: October 1, 2014Date of Patent: December 29, 2015Assignee: St. Jude Medical, Cardiology Division, Inc.Inventor: Don Curtis Deno

Patent number: 8454589Abstract: A system and method for assessing effective delivery of ablation therapy to a tissue in a body is provided. A three-dimensional anatomical map of the tissue is generated and displayed with the map defining a corresponding volume. An index is generated corresponding to a location within the volume with the index indicative of a state of ablation therapy at the location. The index may be derived from one or more factors such as the duration an ablation electrode is present at the location, the amount of energy provided, the degree of electrical coupling between an ablation electrode and the tissue at the location and temperature. A visual characteristic (e.g., color intensity) of a portion of the anatomical map corresponding to the location is then altered responsive to the index.Type: GrantFiled: November 20, 2009Date of Patent: June 4, 2013Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Don Curtis Deno, Stephan P.
