Patent number: 11872358Abstract: A catheter with a variable circular loop is responsive to a contraction wire for increasing the coiling of the circular loop. The shape of the loop is supported by an elongated member, wherein a radially constrictive sleeve confines the contraction wire to extends immediately alongside the length of elongated member so as to improve uniformity and minimize misshaping of the loop during contraction.Type: GrantFiled: February 11, 2021Date of Patent: January 16, 2024Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Ricardo Padilla, Homero Padilla, Julie Bui, Mario Solis, Thomas Selkee, Jose Jimenez, Keshava Datta, Fernando Salazar

Publication number: 20210137593Abstract: A catheter has a distal assembly with at least one loop with ring electrodes. A single continuous puller wire for bidirectional deflection is pre-bent into two long portions and a U-shape bend therebetween. The U-shape bend is anchored at a distal end of a deflectable section which is reinforced by at least one washer having at least two holes, each hole axially aligned with a respective lumen in the deflectable section. Each hole is centered with a lumen so that each puller wire portion therethrough is straight and subjected to tensile force only. A proximal end of the support member is flattened and serrated to provide a better bonding to the distal end of the deflectable section.Type: ApplicationFiled: January 19, 2021Publication date: May 13, 2021Inventors: Julie BUI, Oscar GALVAN, Jose JIMENEZ, Thanh NGUYEN, Ricardo PADILLA, Thomas V.
