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.

International Classification:

A61B 5/042
A61B 18/14
A61B 5/00

Abstract:

A catheter is described with an end effector having densely arrayed electrodes on three loops which are arrayed in various planar configurations when the end effector is unconstrained. The end effector has first, second and third loop members, each loop member includes two spines and a connector that connects the two spines to define a loop extending away from a tubular member of the catheter such that the first, second and third loop members are configured so that each connector of each of the first, second and third loop members is in contact with only one connector of the adjacent loop member.

B29C 63/18

Abstract:

A catheter has a deflection beam with rectangular cross-section and a single continuous puller wire for predictable on-plane bi-directional deflection. The puller wire extends through spacers on opposite sides of the beam so the puller wire is maintained a predetermined separation distance from the beam surface. Tubular structures of the catheter body and the deflectable section are fused at a joint by C-shaped brackets mounted opposite surface of the beam to form a hollow body with holes into which thermoplastic materials covering the catheter body and the deflectable section can melt to form interlocking nodes. Elongated beam stiffeners can be mounted on the beam to provide different curve and deflection geometries.

Abstract:

A catheter has a distal assembly with at least one loop, if not two, with ring electrodes. The distal assembly has an elongated support member covered by an extruded form having two lumens, one sized for nonslip tight fit with the support member. A single continuous puller wire for bidirectional deflection is pre-bent into two long portions and aU-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.
