Publication number: 20240081712Abstract: A catheter for electrophysiology applications is disclosed herein that includes a tubular member and an end effector. The end effector is coupled to a distal portion of the tubular member. The end effector includes first, second, and third loop members configured so that the first loop member defines a first plane, the second loop member defines a second plane at an angle to the first plane, and the third loop member defines a third plane at an angle to the first plane and at an angle to the second plane. Each of the first, second, and third loop members are configured as a respective single axis magnetic coil, and the first, second, and third loop members are collectively configured to function as a three axis magnetic sensor.Type: ApplicationFiled: November 10, 2023Publication date: March 14, 2024Inventors: Thomas V.

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

Patent number: 11850051Abstract: 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.Type: GrantFiled: March 25, 2020Date of Patent: December 26, 2023Assignee: Biosense Webster (Israel) Ltd.Inventors: Thomas Selkee, Keshava Datta, Thanh Nguyen, Anand Rao, Rajesh Pendekanti, Meir Bar-Tal, Ricardo Padilla

Publication number: 20230404425Abstract: An apparatus includes a handle, a catheter, extending distally from the handle, an end effector extending distally from the catheter, a deflection assembly, and a load limiting assembly. The deflection assembly is configured to deflect the end effector away from a longitudinal axis of the catheter. The deflection assembly includes an input member and a translating assembly. The input member is configured to drive the translating assembly to deflect the end effector away from the longitudinal axis. The load limiting assembly is configured to decouple the input member from the translating assembly at a predetermined load such that the input member is inhibited from driving the translating assembly when the input member is decoupled by the load limiting assembly.Type: ApplicationFiled: September 5, 2023Publication date: December 21, 2023Inventors: Ryan Hoitink, Ricardo Padilla, JR., Frank H. Truong

Patent number: 11820452Abstract: A bicycle safety enhancement device includes an elongated member having a distal portion mountable to a bicycle handlebar. A proximity sensor is coupled to a proximal portion of the elongated member and is arranged so that when the elongated member is mounted to a handlebar of a bicycle being ridden by a cyclist, the ultrasonic sensor detects objects adjacent to and/or behind the bicycle and which come within a prescribed distance of the bicycle. An illumination source is coupled to the proximal portion of the elongated member. The illumination source provides a visible warning signal directed toward the detected object when the elongated member is mounted to the handlebar of the bicycle. A camera is coupled to the proximal portion of the elongated member and is arranged to capture images of the detected object as the detected object passes in front of the bicycle being ridden by the cyclist.Type: GrantFiled: October 6, 2021Date of Patent: November 21, 2023Assignee: Arizona Board of Regents on Behalf of the University of ArizonaInventors: Daniel Latt, Rachel J. Sinclair, Tyler J. Mills, Ricardo Padilla Vera, Bridget Slomka, Daniel Taylor, Gavin S. Mitchell

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.

Publication number: 20210059744Abstract: An apparatus includes a catheter having a flexible outer sheath and a flexible irrigation tube. The flexible outer sheath defines a first lumen. The flexible irrigation tube is positioned inside the first lumen and includes an inner layer and an outer coating layer. The inner layer is formed of a synthetic polymer compound and has a uniform cross-section with a hollow interior defining a second lumen. The outer coating layer is disposed around the inner layer. The outer coating layer is formed of a polymeric compound and includes first and second isomers. The first isomer is configured to carry a positive electric charge and the second isomer is configured to carry a negative electric charge.Type: ApplicationFiled: July 30, 2020Publication date: March 4, 2021Inventors: Mohammad Abbas, Ricardo Padilla, JR., Dustin R.
