Publication number: 20240189547Abstract: A guide extension catheter can comprise an elongate tube member, a push member, and a concave track. The elongate tube member can define a lumen and three distinct portions of different diameter. A distal portion can define a first diameter, a proximal portion can define a second diameter which is larger than the first diameter but smaller than a lumen of a guide catheter with which the guide extension catheter is used, and a tapered portion, positioned between the distal portion and the proximal portion, can have a variable diameter. The push member can be eccentrically coupled relative to the tube member and extends proximally therefrom for slidably positioning the tube member within and partially beyond a distal end of the guide catheter. The concave track forms a transition between the tube member and the push member, and defines a partially cylindrical opening leading into the tube member.Type: ApplicationFiled: February 20, 2024Publication date: June 13, 2024Applicant: Teleflex Life Sciences LLCInventors: Joshua Brenizer, Dean Peterson, Mark Wendle

Patent number: 10953197Abstract: Guide extension catheters and related methods are disclosed. A guide extension catheter can comprise an elongate tube member, a push member, and a removable support member. The push member can be eccentrically coupled directly or indirectly to the elongate tube member and can extend proximally therefrom for slidably positioning the elongate tube member within and partially beyond a distal end of a guide catheter. The removable support member can comprise a structure that surrounds at least a portion of the push member. The removable support member alone, or when placed over the push member, can be more rigid along its longitudinal axis than the elongate tube member and can have a cross-sectional dimension that is greater than a maximal cross-sectional dimension of the push member.Type: GrantFiled: October 30, 2019Date of Patent: March 23, 2021Assignee: Teleflex Life Sciences LimitedInventors: Joshua Brenizer, Dean Peterson, Thomas Kouchoukos, Mark Wendle

Patent number: 10722252Abstract: Catheter devices, assemblies and related methods for percutaneous crossing of an occlusion in a blood vessel are disclosed. A catheter device can include a central catheter, two side tubes, and a distally-protruding, curved subintimal guidewire. The central catheter can define a central lumen that extends from a proximal end to a distal end of the central catheter. The lumen can be configured to receive a primary guidewire. The central catheter can also define at least one reentry aperture oriented transverse to the central lumen. The first and second side tubes can be coupled with the central catheter, extending along a longitudinal axis thereof, with the first side tube flanking an opposite side of the central catheter relative to the second side tube. The subintimal guidewire can extend from the first side tube, distally beyond the distal end of the central catheter, to the second side tube.Type: GrantFiled: October 15, 2018Date of Patent: July 28, 2020Assignee: Teleflex Life Sciences LimitedInventors: Joshua Brenizer, Jesse Leonard Farris, III, Thomas Kouchoukos, Mark Wendle, Brandon VanHee, Dean Peterson, Steve Michael, Alexander Marine, Lyndon Carlson
