Publication number: 20240008998Abstract: An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.Type: ApplicationFiled: August 31, 2023Publication date: January 11, 2024Inventors: Charles Branch, Charles Fisher, Mladen Djurasovic, Marcel Dvorak, Sigurd Berven, Anthony J. Melkent, Jonathan M. Dewey, Keith E. Miller, Adriaan J. Kuyler

Patent number: 8317723Abstract: A pressure sensor for connecting to a detector is provided. The pressure sensor comprises: an optical fibre, having a distal end with a distal plane for sensing pressure, a proximal end for communicating with a patch cord, and an In-fibre Bragg grating (FBG) therebetween; a housing, having a distal aperture, a proximal aperture and a bore therebetween, and sized to accept the optical fibre; an annular ring, forming a flexible seal between said optical fibre and housing at least distal to the FBG and a holder for retaining the housing. The FBG is housed in the housing such that in use, axial strain is transferred to said In-fibre Bragg grating housed within said housing by pressure exerted on the distal plane.Type: GrantFiled: February 22, 2007Date of Patent: November 27, 2012Assignee: UVic Industry Partnerships Inc.Inventors: Christopher Raymond Dennison, Peter Martin Wild, David Robert Wilson, Peter A. Cripton, Marcel Dvorak

Patent number: 8246625Abstract: An instrument is provided for reduction of a rod or other elongated member into an implant, such as a bone screw. In one embodiment, such an instrument includes a rod adjusting assembly pivotably attached to an implant holding assembly. The implant holding assembly can be pivotably connected to an implant, and the rod adjusting assembly is operable to move a rod toward or away from the implant holding assembly. In that embodiment, several motions are possible by the instrument so that relatively small or large movements of a rod with respect to an implant may be made.Type: GrantFiled: August 24, 2010Date of Patent: August 21, 2012Assignee: Warsaw Orthopedic, Inc.Inventors: Keith E. Miller, Alan Rezach, Greg Denzer, Christopher Shaffrey, Marcel Dvorak, Charles Fisher, Jeff Wang, Ricardo C. Sasso
