Publication number: 20230293214Abstract: Disclosed are cable fixation devices. The fixation devices are configured to keep tension in a polymer cable to secure a fracture or for other medical uses. In an embodiment, a fixation device for securing a fracture comprises a body and a piercing element, wherein the fixation device is configured to pierce a polymer cable arranged in the body by engaging the piercing element. In an embodiment, the fixation device further comprises a retensioning member, which may be operated to increase tension in the polymer cable after the polymer has been pierced by the piecing element. In an embodiment, the polymer cable comprises a braid or a yarn.Type: ApplicationFiled: May 18, 2023Publication date: September 21, 2023Inventors: William T. FISHER, Dennis M. SAURO, Timothy O'NEIL

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

Patent number: 9931166Abstract: Various embodiments of an offset catheter are provided. In some embodiments, an offset catheter includes a guidewire tube and a catheter coupled with an elastic and/or compressible rib. The compressible rib provides an offset or separation between the catheter and the guidewire tube in its resting state. The rib has an initial resting state, but may be forced into a compressed state. When released from the compressed state, the rib returns to its resting state. An offset catheter may be compressed and slid through a sheath. When the offset catheter emerges from the sheath, the distal tip will return to its resting state providing an operation offset.Type: GrantFiled: August 5, 2016Date of Patent: April 3, 2018Assignee: The Spectranetics CorporationInventors: Dennis M. Sauro, William T. Fisher

Patent number: 8267871Abstract: An apparatus for modulating the pressure of a fluid such as a gas within the expandable portion of a guide wire catheter. A preferred embodiment apparatus features a mechanism for controllably gripping and releasing the open, proximal end of a tubular guide wire, a mechanism for introducing a fluid to a desired pressure and volume into the expandable portion of the tubular guide wire through the open end, and, while maintaining the pressure and volume of fluid in the tubular guide wire, a mechanism for introducing a sealing member into the open end of the tubular guide wire to seal the fluid in the tubular guide wire. In a particularly preferred embodiment, the apparatus also features a deflation tool for piercing the seal and letting the fluid out. Using this apparatus, the tubular guide wire can be re-sealed and re-opened as necessary.Type: GrantFiled: May 6, 2004Date of Patent: September 18, 2012Assignee: Kensey Nash CorporationInventors: Mark Eberhardt, William T.
