Patent number: 10751187Abstract: An intersomatic cage, an intervertebral prosthesis, an anchoring device and an instrument for implantation of the cage or the prosthesis and the anchoring device are provided. An intersomatic cage or an intervertebral prosthesis fit closely to the anchoring device, which includes a body of elongated shape on a longitudinal axis, of curved shape describing, along the longitudinal axis, an arc whose dimensions and radius of curvature are designed in such a manner that the anchoring device may be implanted in the vertebral plate of a vertebra by presenting its longitudinal axis substantially along the plane of the intervertebral space, where the anchoring device is inserted, by means of the instrument, through a slot located in at least one peripheral wall of the cage or on at least one plate of the intervertebral disc prosthesis to penetrate into at least one vertebral plate.Type: GrantFiled: October 24, 2017Date of Patent: August 25, 2020Assignee: LDR MedicalInventors: Jerome Allain, Jean Lombard, Jeff Phelps, Pierce Nunley, Charles Gordon, Vincent Leone, Michael Hisey

Patent number: 9987051Abstract: An interbody spacer is disclosed and includes a body portion defining a longitudinal axis. The longitudinal axis includes a distal end portion, a proximal end portion, opposed side surfaces that extend between the distal and proximal end portions, and top and bottom surfaces configured and adapted to engage vertebral bodies. The body portion includes a cavity defined through the top and bottom surfaces that increases in width at a medial position thereof. The cavity is configured to retain biological material therein. A method of performing spinal surgery is also disclosed.Type: GrantFiled: January 27, 2016Date of Patent: June 5, 2018Assignee: K2M, Inc.Inventors: Pierce Nunley, Stephanie Volk, Kaitlyn McClymont

Patent number: 9782158Abstract: A surgical access device including a frame, first and second supports, and first and second retractor blades releasably coupled with the first and second supports, respectively. The frame has first and second arms. The first support is releasably coupled with the first and second arms. The second support is slidably mounted on the first and second arms. The second support is movable between a first position with the retractor blades in close cooperative position and a spaced apart position with respect to the first support. The first and second retractor blades each have a distal end portion configured and adapted to engage a vertebral body. In one method of use, the retractor is inserted through an incision in first orientation with the blades in close approximation and rotated approximately 90°, before spreading the retractor blades to retract tissue.Type: GrantFiled: December 3, 2015Date of Patent: October 10, 2017Assignee: K2M, Inc.Inventors: Pierce Nunley, Colin Natali, Faheem Sandhu, Ronald Childs, Brandon Moore

Patent number: 9468535Abstract: An intervertebral implant includes a body portion defining a longitudinal axis. The body portion includes a distal end portion, a proximal end portion, anterior and posterior walls that extend between the distal and proximal end portions, and top and bottom surfaces. At least one of the top and bottom surfaces includes a plurality of substantially concentrically arranged ridges configured and adapted to engage vertebral bodies. In particular, the plurality of substantially concentrically arranged ridges are a plurality of ring-shaped protrusions that define a generally saw-tooth pattern in a radial direction.Type: GrantFiled: October 11, 2011Date of Patent: October 18, 2016Assignee: K2M, Inc.Inventors: Pierce Nunley, Brandon Moore, Stephanie Volk

Patent number: 9247969Abstract: A rod reduction device includes a housing defining a longitudinal axis. The housing has first and second arms extending distally therefrom. The distal ends of the arms are configured to releasably attach to a bone anchor. An anvil is operatively associated with the first and second arms of the housing and translatable along the longitudinal axis for facilitating the insertion of a spinal rod into the bone anchor. The anvil and each arm are positionable between an open position and a closed position.Type: GrantFiled: October 19, 2012Date of Patent: February 2, 2016Assignee: K2M, Inc.Inventors: Pierce Nunley, Michael Barrus, Scott Jones
