Double loop lasso catheter with single puller wire for bi-directional actuation
Summary
USPTO published patent application US20260090835A1 for a double loop lasso catheter with single puller wire enabling bi-directional deflection. The invention features a pre-bent puller wire with U-shape bend anchored at a deflectable section reinforced by washers with aligned holes for straight tensile force application. The proximal support member is flattened and serrated for improved bonding.
What changed
USPTO published patent application US20260090835A1 filed October 2, 2024 (Application No. 18904894), covering a catheter distal assembly with at least one loop containing ring electrodes. The key innovation is a single continuous puller wire for bi-directional deflection, pre-bent into two long portions connected by a U-shape bend. The U-shape bend anchors at the distal end of a deflectable section reinforced by at least one washer with holes axially aligned to respective lumens, ensuring each puller wire portion passes straight through and is subjected to tensile force only.

Abstract
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.
