Patent number: 9248255Abstract: A catheter has a deflection beam and a single continuous puller wire to effectuate bi-directional deflection. A joint between a catheter body and a deflectable distal section effectively transmits torque from a control handle. The joint includes two open-shaped brackets, each affixed to a respective side of the flat deflection beam to form a closed-shaped hollow body that bridges and circumferentially encircles the beam. Each bracket has through-holes into which thermoplastic material of the catheter body and the deflectable distal section can melt and migrate to form interlocking nodes.Type: GrantFiled: November 14, 2012Date of Patent: February 2, 2016Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventor: Thomas V.

Patent number: 9199061Abstract: A medical device control handle has with a distal component which is adjustable by an actuator assembly by means of a puller member or wire. The actuator assembly includes a user interface rotational dial, a detent tab washer and a spool, where the dial is rotationally coupled to the detent tab washer which transmits rotational movement of the dial to the spool. The spool has a shaft body and a drum end onto which an proximal end portion of the puller member can be wound to manipulate or adjust the distal component. Rotational movement of the detent washer is limited to prevent overrotation and breakage of the puller member. At least one washer is mounted on the shaft body of the spool to help apply compression load on the actuator assembly in friction-inducing contact with one or more components of the actuator assembly.Type: GrantFiled: November 18, 2011Date of Patent: December 1, 2015Assignee: Biosense Webster (Israel) Ltd.Inventor: Thomas V.

Publication number: 20150335862Abstract: A medical device control handle has a first actuation assembly and a second actuation assembly, wherein each assembly has a shaft that is axially aligned but not rotationally coupled with the other shaft. The first actuation assembly includes a first actuation member and a clutch mechanism having a friction disk for generating frictional torque in rendering the first actuation member self-holding. The first actuation member has a cam portion adapted to impart translational motion and rotational motion for disengaging the clutch mechanism upon pivotation of the first actuation member, thus allowing rotation of the first shaft to manipulate a feature of the medical device, for example, deflection. The second actuation assembly includes a second actuation member and a translating member that is responsive to rotation of the second shaft so as to manipulate another feature of the medical device. The second actuation member is also self holding.Type: ApplicationFiled: August 5, 2015Publication date: November 26, 2015Inventor: Thomas V. Selkee

Publication number: 20150265345Abstract: 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 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: June 8, 2015Publication date: September 24, 2015Inventors: Julie Bui, Oscar Galvan, Jose Jimenez, Thanh Nguyen, Ricardo Padilla, Thomas V.

Publication number: 20150148741Abstract: The present invention provides a bi-directional catheter with nearly double the throw in its catheter tip deflection. In particular, the travel path of each the puller wire includes a U-turn or doubling-back around a pulley which minimizes the offset angle between the puller wire and the longitudinal axis of the control handle while maximizing the travel distance of that puller wire for any given distance traveled by the pulley drawing the puller wire. In one embodiment, the catheter has an elongated catheter body, a catheter tip section with first and second diametrically-opposed off-axis lumens, and a control handle which includes a steering assembly having a lever structure carrying a pair of pulleys for simultaneously drawing and releasing corresponding puller wires to deflect the tip section of the catheter.Type: ApplicationFiled: January 28, 2015Publication date: May 28, 2015Inventor: Thomas V.

Patent number: 8882705Abstract: An improved steerable catheter with in-plane deflection comprises a catheter body having proximal and distal ends and a lumen extending therethrough and a tip section at the distal end of the catheter body. The tip section comprises a flexible plastic tubing having a pair of diametrically-opposed lumens extending therethrough. The catheter also provides two puller wires manipulated through a control handle at the proximal end of the catheter body. Each puller wire extends through one of the pair of lumens in the tip section and through the lumen of the catheter body and is anchored to the control handle at its proximal end and anchored to the tip section at its distal end. The deflection mechanism is configured to generally define a plane along which deflection most readily occurs and an edge along which deflection is most readily avoided.Type: GrantFiled: May 18, 2011Date of Patent: November 11, 2014Assignee: Biosense Webster, Inc.Inventors: Benjamin D.

Publication number: 20140135686Abstract: 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.Type: ApplicationFiled: November 14, 2012Publication date: May 15, 2014Inventors: Jose Jimenez, Ricardo Padilla, Thomas V.
