Patent number: 11872026Abstract: A spring assembly usable with an intravascular catheter can include a tubular body, two mounting surfaces, and a compressible framework. The tubular body extends along a longitudinal axis and is sized to traverse vasculature. Each mounting surface can be configured to engage a substantially planar electrical circuit and is positioned in the tubular body each in a respective plane perpendicular to the longitudinal axis. The mounting surfaces face toward each other in opposite directions. The compressible framework extends between the first and second mounting surfaces. The spring assembly can further include a pair of electrical circuits mounted to the pair mounting surfaces. Each electrical circuit can include an inductive coil such that the pair of electrical circuits is a distance transducer. A change in distance between the pair of electrical circuits can be detected when the compressible framework is compressed and/or bent.Type: GrantFiled: November 20, 2020Date of Patent: January 16, 2024Assignee: Biosense Webster (Israel) Ltd.Inventors: Corey Rousu, Matthew Hitzeroth

Publication number: 20230389955Abstract: A device for introduction into a body vessel includes a shaft, a balloon positioned at the distal end of the shaft, a guidewire disposed longitudinally within the shaft to receive a guidewire during use, a balloon disposed at the distal end of the shaft, and longitudinal scoring wires to score a vascular lesion attached to the distal end of the shaft, disposed over the balloon and disposed within the shaft. The proximal ends are welded or otherwise affixed to a spring mounted in the handle. The balloon expands when fluid is delivered to the balloon through the inflation lumen. This expansion pushes the scoring wires against the vascular lesion.Type: ApplicationFiled: August 16, 2023Publication date: December 7, 2023Inventors: Melissa Boyle, Corey Rousu, Mark Nicholas Wright

Patent number: 11701166Abstract: A method of manufacturing a catheter tip by electroplating a conductive material over an insert comprising a negative to a domelike shape thereby forming a shape of the catheter tip comprising a dome with the domelike shape, selectively positioning a plurality of irrigation holes between outer and inner surfaces of the catheter tip, removing the insert thereby leaving the catheter tip and the plurality of irrigation holes, and electropolishing the catheter tip. In other examples, the insert is not removed and instead the step of electroplating causes the insert to be encapsulated with the conductive material thereby forming the catheter tip.Type: GrantFiled: November 13, 2020Date of Patent: July 18, 2023Assignee: Biosense Webster (Israel) Ltd.Inventors: Corey Rousu, Daniele Ghidoli, Matthew Hitzeroth

Patent number: 10532187Abstract: A steerable catheter is disclosed, having an elongated, tubular catheter body with at least one deflection member slidably disposed within a lumen, secured at a distal end to a tip section and terminating in an interconnect at a proximal end and a handle releasably attached to the proximal end of the catheter body. The handle has at least one sliding member coupled to an actuator, such that manipulation of the actuator causes relative longitudinal movement with respect to the handle, wherein the interconnect and the sliding member engage when the handle is attached to the catheter body so that the relative longitudinal movement of the sliding member is transmitted to the deflection member and wherein the interconnect and the sliding member disengage when the handle is released from the catheter body.Type: GrantFiled: October 17, 2017Date of Patent: January 14, 2020Assignee: Biosense Webster (Israel) Ltd.Inventors: Jeffrey Schultz, Corey Rousu, Daniele Ghidoli, Simon Jung, Jeffrey Clark
