Patent number: 9265533Abstract: A spinal rod persuader, system and method can include an outer tube, an inner tube, and a locking element. A first actuation mechanism can be movable in a linear fashion along a longitudinal axis direction to cause the locking element to move in a linear fashion over the inner tube and to lock the inner tube onto a pedicle screw. A second actuation mechanism can be rotated to cause the outer tube to move in a longitudinal axis direction with respect to the inner tube to push the spinal rod into a final position with respect to the pedicle screw while the pedicle screw is locked to the inner tube. A slot and/or tab structure can be provided in the outer tube such that actuation of the slot/tab will allow disassembly of the inner tube, outer tube and locking element with respect to each other.Type: GrantFiled: September 4, 2013Date of Patent: February 23, 2016Assignee: AESCULAP IMPLANT SYSTEMS, LLCInventors: Gregory Nelson, Dennis B Van Blargan, James D Hughett

Patent number: 7311656Abstract: A transfer device usable in a system for intraluminal treatment of a selected site in a body of a patient in which the transfer device comprises an integral pump for pressurizing and circulating fluid through a fluid path defined by the transfer device and associated catheter. A removable fluid cartridge is provided including a reservoir from which fluid is drawn by the pump and into which fluid is returned after being circulated through the fluid path. The pump may be a peristaltic pump and the fluid cartridge may include an elongated fluid pick-up having an inlet through which fluid is introduced into the transfer device. The fluid pick-up is sized in length so that the inlet is always submerged in the fluid regardless of the orientation of the transfer device. A removable treatment cartridge having a lumen forming part of the fluid path may also be provided, and a storage sleeve for the treatment cartridge may be of a radiation-blocking material, such as quartz.Type: GrantFiled: October 27, 2003Date of Patent: December 25, 2007Assignee: Best Vascular, Inc.Inventors: James D. Hughett, Robert Michael Webster, Douglas Layland Armstrong, Byron Lee Boylston, Gregg T. Juett, Richard A. Hillstead, Jack C. Griffis, III, Andrew L. Lerohl, Mark Dehdashtian, Marvin A. Guiles

Patent number: 5330087Abstract: A surgical stapler having a trigger attached to a ratcheting mechanism for preventing the refiring of the stapler trigger with a staple loaded within a forming mechanism. In addition, the mechanism contains driver buffering means to prevent the sharp reduction in opposing force driving formation of a staple. The staples are constantly maintained in proper orientation during transfer from a track to the forming site, and are self-centering on the former, and have an oversized crown so that cold-worked areas on each staple do not hinder forming.Type: GrantFiled: May 14, 1993Date of Patent: July 19, 1994Assignee: Ethicon, Inc.Inventors: Michael A. Murray, John F. Love, James D. Hughett, Randy R. Stephens, Richard F. Schwemberger

Patent number: 4796793Abstract: A surgical stapler includes a moving driver and an anvil moving in the same direction as the driver to pick off a staple from a supply, and to transport it to a forming station. The anvil is there stopped, but the driver continues to move forwardly forming the staple about the anvil. The anvil is locked against retraction until the driver is partially retracted in order to facilitate staple ejection. A drive linkage includes a four-bar linkage and a trigger mounted cam drive for dispersing required input forces over the trigger movement and minimizing force variations and maximum input. Modular features and construction provide use and manufacturing advantages. Methods are included.Type: GrantFiled: May 10, 1984Date of Patent: January 10, 1989Assignee: Ethicon, Inc.Inventors: George D. K. Smith, James D. Hughett, Thomas E. Warman
