Publication number: 20220338852Abstract: A closure device system for sealing a percutaneous puncture in a vessel wall can comprise a toggle configured to engage an interior surface of the vessel wall, a plug configured to engage an exterior surface of the vessel wall, and a suture that extends through the plug and through the toggle along at least a first direction so as to couple the toggle to the plug. The system can further comprise a tube that extends through the plug and through the toggle along the first direction such that a distal end of the tube is disposed distally to the toggle. The tube can define a guidewire lumen that extends therethrough along the first direction. And the guidewire lumen can be configured to receive a guidewire that protrudes from the vessel wall such that the plug, toggle, and tube are slidable along the guidewire toward the vessel wall.Type: ApplicationFiled: July 11, 2022Publication date: October 27, 2022Applicant: Teleflex Life Sciences LimitedInventor: Greg Walters

Patent number: 10517633Abstract: A device suitable for removing material from a living being is provided, featuring at least an aspiration pump, powered by a motor. The aspiration pump and any optional infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. The helical pumping mechanism may be a helical coiled wire about a central core tube. The helical coil wire, whether together with, or independent of, the core tube, may be rotated to cause a pumping action. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. In one embodiment, the system comprises a wire-guided mono-rail catheter with a working head mounted on a flexible portion of the catheter that can laterally displace away from the guide wire to facilitate thrombus removal.Type: GrantFiled: September 16, 2017Date of Patent: December 31, 2019Assignee: THE SPECTRANETICS CORPORATIONInventors: John E. Nash, Greg Walters, Dennis M. Sauro, Mark Eberhardt, William T. Fisher, Douglas G. Evans

Publication number: 20140277114Abstract: A method of sealing a vascular puncture of a vessel can include the step of inserting a guidewire through a sheath and into the vessel. The guidewire can include a hollow tube and a balloon coupled to a distal end of the hollow tube. The method can further include the steps of inflating the balloon so as to temporarily occlude the vessel and guiding a closure device along the hollow tube toward the puncture such that a toggle of the closure device enters the vessel through the puncture; and sealing the puncture with the closure device.Type: ApplicationFiled: March 6, 2014Publication date: September 18, 2014Applicant: Essential Medical, Inc.Inventor: Greg Walters

Publication number: 20140263261Abstract: An energy consumption controller may be communicatively coupled with a plurality of alternative energy sources and an engine. The controller may be configured to manage energy consumption from the alternative energy sources interconnected with the engine and to keep the engine within a desired temperature range. Within the desired temperature range, the engine will start and run at a full load more rapidly than if the engine cooled excessively. The controller may change the selected energy source as required, based on factors such as cost, engine maintenance and testing and/or imminent need of the engine.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Inventors: James Hunt, Greg Walters, Clinton Hermance, Joe Gaylord, Chris McFarland, Micky Merritt
