Patent number: 10426532Abstract: A bone plate system for securing a plurality of bones is provided including a plate member, a locking device of the bone plate, and a surgical cable having a trailing end for being connected to the bone plate and a leading end for being advanced around the bones and into the locking device. The surgical cable may be tensioned to approximate the bones, urge the bones together, and seat the bone plate against the bones. The locking device may be reconfigured to a locked configuration to fix the bone plate to the surgical cable. The bone plate further includes a plurality of throughbores for receiving bone anchors that rigidly fix the bone plate to the bones. The bone plate system utilizes the tensile strength of the surgical cable and the rigid fixation between the bone anchors and the bone plate to resist relative movement of the bones.Type: GrantFiled: February 1, 2017Date of Patent: October 1, 2019Assignee: A&E Advanced Closure Systems, LLCInventors: Robert Goodwin, Peter Didyk, Jamie Close, Matthew Gephart

Publication number: 20080045956Abstract: A minimally invasive surgical system for implanting pedicle screw assemblies to be connected by a spinal rod is disclosed. In one form, the system includes a plurality of holding mechanisms for the pedicle screw assemblies, each holding mechanism for being inserted through an incision and configured to receive tools along an axis thereof for driving a screw anchor of the pedicle screw assembly into a vertebra and securing the spinal rod thereto and a rod inserter that is configured to adjustably hold the rod and insert the rod through a common incision with one of the holding mechanism for being fed into position in an initial direction that is transverse to the axes of the holding mechanisms.Type: ApplicationFiled: August 23, 2007Publication date: February 21, 2008Applicant: PIONEER LABORATORIES, INC.Inventors: Matthew Songer, Matthew Gephart, Phillip Berman, Bobby Lynch, Ernie Corrao

Publication number: 20070203399Abstract: A retraction apparatus and method are disclosed that provide optimized access to a surgical site. In one form, a retraction frame has a retraction opening with two sets of blades operating therein. The blades are used to sequentially retract the tissue from about an incision. The sequential retraction of the blades generates only narrow gaps between the blades so that tissue and blood encroachment during the surgical procedure are minimized.Type: ApplicationFiled: October 6, 2006Publication date: August 30, 2007Inventors: Matthew Gephart, Phillip Berman

Publication number: 20060161157Abstract: Bone plate systems and retainers are provided for surgical implants and bone repair. The bone plate is multi-tiered for receiving bone anchors or screws for securing multiple bones or bone fragments in a desired relationship. The plate includes bores for receiving the screws, and the bores may permit and define a translation path for the screws relative to the plate. The retainers are held in a recess in the bores to prevent screw back-out. Once the screw is seated with the plate, the retainer rests over a top surface of the screw to impede screw back-out from the plate. The retainer may expand to permit driving a screw therethrough and may contract once the screw is seated within the plate so the retainer is in a configuration for preventing back-out. Tools and methods are also provided for implantation and removal of the plates and the screws.Type: ApplicationFiled: October 26, 2005Publication date: July 20, 2006Inventors: Lawrence Mosca, Matthew Gephart, Brian Janowski, Brad Fredin, Francis Korhonen, Matthew Songer

Publication number: 20050256581Abstract: Artificial disc devices are disclosed that restore correct anatomical intervertebral spacing for damaged discs while maintaining a substantially normal range of biomechanical movement for the vertebrae between which they are implanted. The disc devices include center bearing and outer or annular bearing portions with the center bearing portion including generally axially extending locating surfaces which cooperate with the facing vertebral surfaces to resist migration. The outer bearing portion is for load bearing or load sharing with the center bearing portion and includes surfaces that extend radially toward the periphery of the vertebrae so that subsidence about the center bearing portion is minimized. Alternate forms of the disc devices include one with an axially enlarged center ball bearing having an annular ring bearing extending thereabout and another having upper and lower plate members with a central bumper member and a surrounding resilient annular member therebetween.Type: ApplicationFiled: July 19, 2005Publication date: November 17, 2005Inventors: Matthew Songer, Thomas Kilpela, Brian Janowski, Gregory Berrevoets, Matthew Gephart
