Patent number: 11950897Abstract: A catheter has single axis sensors mounted directly along a portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are on a linear or nonlinear single axis sensor (SAS) assembly. The catheter includes a catheter body and a distal 2D or 3D configuration provided by a support member on which at least one, if not at least three single axis sensors, are mounted serially along a length of the support member. The magnetic-based sensor assembly may include at least one coil member wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system. The joint region provides strain relief adaptations to the at least one coil member and the respective cable member from detaching.Type: GrantFiled: December 12, 2022Date of Patent: April 9, 2024Assignee: BIOSENSE WEBSTER, INC.Inventors: Maribeth Esguerra Wilczynski, Jennifer Maffre, Thanh Nguyen

Publication number: 20230404663Abstract: The disclosed technology includes a method of ablating tissue including positioning an electrode into contact with tissue and applying a first ablation signal to the tissue. The method can include forming a first lesion comprising a first depth with little or no first temperature change in a temperature of the tissue. The method can include applying a second ablation signal to the tissue different from the first ablation signal. Applying the second ablation signal to the tissue can include forming a second lesion comprising a second depth and generating a second temperature change in the tissue different from the first temperature change by at least 10° C. The method can include forming a combined lesion comprising the first lesion and the second lesion and comprising a combined size. The combined depth can be about 20% to about 40% greater than either of the first depth and the second size.Type: ApplicationFiled: August 30, 2023Publication date: December 21, 2023Inventors: Tushar SHARMA, Jennifer MAFFRE, Assaf GOVARI, Atul VERMA

Patent number: 8287532Abstract: A catheter adapted for mapping and ablating epicardial tissue from the pericardial cavity includes a catheter body and an electrode assembly that has a tip section and a loop member lying generally within a plane, wherein the tip section includes an ablation electrode exposed on one side of the loop member and an insulation member exposed on an opposite side of the loop member. The catheter also includes a intermediate section between the catheter body and the electrode assembly, wherein the intermediate deflects the loop member and the tip section bi-directionally within the same plane. So arranged, the catheter can be safely maneuvered in the pericardial sac and swept in a side to side motion over the epicardium with the ablation electrode reliably facing and making contact with the epicardium. The tip section can include a balloon that is inflatable to push away surrounding pericardial tissue.Type: GrantFiled: April 13, 2009Date of Patent: October 16, 2012Assignee: Biosense Webster, Inc.Inventors: Sean Carroll, Jennifer Maffre, Maribeth Esguerra

Publication number: 20120179105Abstract: A catheter system includes a flexible abutment at its distal end. Functionally, the abutment serves to stabilize and align (orient) the distal portion of the catheter as its distal tip is advanced into contact with a tissue surface. Structurally, the flexible abutment is an arrangement of wires that creates a hollow conical shaped frame having two open ends. One end is affixed to the distal end of the catheter. And, the other is presented as a plurality of separated end points that collectively define an annulus at a distal distance from the catheter's tip. For its operation, the flexible abutment is moved from a folded (tube-shaped) configuration, for travel through the vasculature of a patient, to a flared configuration with end points on the frame extended outwardly from the catheter axis, for contact with the tissue surface.Type: ApplicationFiled: January 11, 2011Publication date: July 12, 2012Inventors: Richard A. Schatz, Christopher J. Birchard, Jennifer Maffre
