Publication number: 20200297281Abstract: An apparatus includes a shaft and an end effector at a distal end of the shaft. The end effector is sized to fit in an anatomical passageway within a subject's cardiovascular system. The end effector includes at least one electrode pair that is configured to contact cardiovascular tissue and thereby pick up electrocardiogram signals. Each electrode pair includes first and second electrodes spaced apart along a longitudinal axis from each other by a gap area located between the electrodes, the gap area having a gap length with respect to the longitudinal axis such that a length of one of the electrodes along the longitudinal axis is equal to or greater than the gap length; and a ratio of an area defined by the gap area to one electrode area is equal to or less than one.Type: ApplicationFiled: March 17, 2020Publication date: September 24, 2020Inventors: Shubhayu Basu, Meir Bar-Tal, Mario A. Solis, Michel Haissaguerre, Pierre Jais, Meleze Hocini, Olivier Bernus, Rémi Dubois, Masateru Takigawa

Patent number: 9149198Abstract: A medical device including a catheter having a shaft with a distal portion; a first plurality of substantially hemispherical electrodes coupled to the distal portion; a second plurality of substantially hemispherical electrodes coupled to the shaft proximal of the first plurality, where the second plurality of electrodes are oriented substantially orthogonal to the first plurality of electrodes; and an additional electrode coupled to the shaft. A console may have a processor in electrical communication with the first and second plurality of electrodes and the reference electrode, the processor programmed to obtaining a monophasic action potential recording from at least one of the first and second plurality of electrodes.Type: GrantFiled: February 18, 2014Date of Patent: October 6, 2015Assignee: Medtronic Ablation Frontiers LLCInventors: Randell L. Werneth, Meleze Hocini, Mark T. Stewart, Dan Wittenberger, Timothy J. Corvi, Michael T. Lau, Vinod Sharma

Patent number: 8571626Abstract: Catheters and methods for obtaining monophasic action potential (“MAP”) electrograms include a flexible catheter body defining a longitudinal axis, and a distal assembly affixed to the catheter body distal end defining a distal tip. The distal assembly has at least three MAP recording electrodes, and at least one reference electrode for determining reference potential. The recording electrodes are each positioned a radial distance from the longitudinal axis in at least three different radial directions, defining a recording geometry substantially having radial symmetry. The reference electrode is a longitudinal distance from the recording geometry. Optional features include a steerable catheter shaft, one or more radio-frequency ablation electrodes, and a dedicated pacing electrode. Different possible embodiments include a dome housing having the recording electrodes in a fixed spatial arrangement, and a distal loop assembly having an array of electrodes on at least three flexible loop elements.Type: GrantFiled: September 5, 2012Date of Patent: October 29, 2013Assignee: Medtronic Ablation Frontiers LLCInventors: Michael Lau, Randell L.
