Patent number: 9259253Abstract: The present invention relates to a series of orthopedic plates for use in repair of a bone. The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and either one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge.Type: GrantFiled: March 31, 2014Date of Patent: February 16, 2016Assignee: ORTHOHELIX SURGICAL DESIGNS, INC.Inventors: David B. Kay, Lee A. Strnad, Dustin Ducharme, G. Martin Wynkoop

Patent number: 9204912Abstract: This invention provides a calcaneal plate implanted using a sinus tarsi approach and comprises an anterior section having two locking screw holes, an s-shaped posterior facet section having a four locking holes and which rounds toward the bone at both the inferior and superior edges and is reinforced at the superior edge, and a blade shaped posterior portion having three linearly aligned locking holes and terminating in a tapered portion. There is also, a drill guide assembly having a drill guide column inserted through a hole in a targeting guide and locking to one of the locking holes in the plate, and cannulated drill guide sleeves that lock into holes in the targeting guide in a spaced relation whereby when the targeting guide is locked into the plate, the targeting guide can be used as a handle and wherein locking screws can be implanted percutaneously.Type: GrantFiled: September 3, 2013Date of Patent: December 8, 2015Assignee: ORTHOHELIX SURGICAL DESIGNS, INC.Inventors: James P. Price, Michael A. Zwolinski, Andrew J. Leither, David B. Kay, Bryan D. Den Hartog, David B. Thordarson, John L. Marsh, Derek S. Lewis

Patent number: 9149313Abstract: An orthopedic plate has a portion with a curved bottom surface that is designed to extend longitudinally along the bone and change the inferior curve as it advances proximally along the bone from a shallower to a sharper radius and further spirals downward as the plate advances. The plate includes a set of tabs, offset from the longitudinal axis of the plate to provide for better pullout values. The ears may be located at the terminal portion of the plate or somewhat more intermediate to the terminus of the plate, depending on the intended application. A point in the center of the central screw hole can be used to define the origin of the plate, and the angles of the screw and/or pegs holes can be referenced with Z, Y, and Z coordinates relative to this central hole.Type: GrantFiled: July 24, 2014Date of Patent: October 6, 2015Assignee: ORTHOHELIX SURGICAL DESIGNS, INC.Inventors: Lee Strnad, David B. Kay, Amanda Martin, G. Martin Wynkoop

Publication number: 20150272639Abstract: An orthopedic plate has a first end including a locking screw hole that receives a locking screw and spaced from that hole is a closed compression housing that extends from the bone-facing side of the plate and which receives a compression screw that forms an angle of from about 10° to about 70° with a longitudinal axis of the plate. The compression housing is not located on the medial line of the plate, but is peripheral to the medial line, either in the longitudinal or the medial direction of the plate.Type: ApplicationFiled: May 15, 2015Publication date: October 1, 2015Inventors: Derek S. Lewis, Elizabeth Altenau, Gordon Bennett, Bryan D. Den Hartog, Jackson R. Heavener, Brian Hockett, Jeffrey Johnson, David B. Kay, Andrew Leither, Ellen Pokorney, Allison Wright

Patent number: 9091523Abstract: A profilometer incorporating a partial coherence interferometer directs a beam containing a band of wavelengths along object and reference arms of the interferometer into respective engagements with a test object surface and a reference object surface en route to a spectrometer for measuring a spectrum of the beam. Within the object arm, the test object surface is relatively moved through a range of positions offset from a null position at which optical path lengths of the object and reference arms are equal. Modulation frequencies of the beam spectrum are calculated at a succession of different focus spot positions across the test object surface. Changes in the modulation frequency are interpreted to distinguish between optical path length differences at which the optical path length of the object arm is longer or shorter than the optical path length of the reference arm.Type: GrantFiled: July 19, 2013Date of Patent: July 28, 2015Assignee: Quality Vision International, Inc.Inventor: David B.

Publication number: 20150164563Abstract: The invention comprises an implant having a first end section and a second end section, where the first end has a cancellous thread for implantation in a first section of bone and the second end includes expansion slots and barbs or wings, that that resist movement out of a second section of bone. These anchors expand outwardly when a rigid wire, such as a k-wire is fed through a central cannulation in the implant and either the wire expands in diameter or the cannulation decreases in diameter. The implant also includes a collar intermediate to the first and second section which includes one or more surfaces to allow the first section to be screwed into a first bone section.Type: ApplicationFiled: February 17, 2015Publication date: June 18, 2015Applicant: ORTHOHELIX SURGICAL DESIGNS, INC.Inventors: Derek S.

In a further embodiment, the plate also includes a second end with a chamfer for insertion of the plate into bone, and in a still further embodiment, the plate is an MTP plate.Type: GrantFiled: February 14, 2012Date of Patent: April 14, 2015Assignee: Orthohelix Surgical Designs, Inc.Inventors: Derek S.

Patent number: 8998903Abstract: An orthopedic plate is designed for opening osteotomies and includes a contoured double tabbed or butterfly shaped plate portion which can accommodate selective fixation including locking, variable locking and non-locking. The plate also includes a centrally located osteotomy support that maintains the opening between bone segments at a spaced relationship. The support can be integral to the plate, or can be modular, i.e. a separate and adjustable segment which can be changed to accommodate the desired geometry of the osteotomy site.Type: GrantFiled: March 10, 2011Date of Patent: April 7, 2015Assignee: Orthohelix Surgical Designs, Inc.Inventors: James Price, Bryan D. Den Hartog, Derek S. Lewis, David B. Kay, Michael C. McGlamry, Terry Philbin, Mark Scioli

Patent number: 8986353Abstract: An orthopedic plate is specifically configured for use in osteotomies, in which part of the plate extends into a portion of a first bone segment and part is external to the cortical surface of an adjacent bone segment to fix the segments to allow them to fuse. The plate has a first end and a second end where the end which is inserted into the bone has a chamfer and a through hole having a hole axis optionally at an oblique angle to the longitudinal axis of the plate, and which can receive a screw, peg or pin. The second end of the plate includes a locking screw hole and optionally including a compression slot extending in a direction toward a screw hole in the opposing end. Optionally, the non-locking hole has a shroud that forms an arc or portion of a cylinder over the hole. A plate driver having a recess that holds the plate is used to insert the plate into the bone.Type: GrantFiled: July 8, 2010Date of Patent: March 24, 2015Assignee: Orthohelix Surgical Designs, Inc.Inventors: Jeffrey Johnson, David B.
