Patent number: 11779470Abstract: A driving instrument for adjusting a spinal implant includes an outer shaft having a distal end configured to actuate a proximal adjustment assembly of a spinal implant, and an inner shaft having a distal end configured to actuate a distal adjustment assembly of the spinal implant. The inner shaft is disposed within the outer shaft, with a proximal end of the inner shaft extending proximally from the outer shaft. The proximal end is configured to be rotated such that rotation of the inner shaft results in simultaneous rotation of the inner and outer shafts, with rotation of the outer shaft ceasing at a first value of resistance associated with the proximal adjustment assembly and rotation of the inner shaft ceasing at a second value of resistance associated with the distal adjustment assembly such that cessation of rotation of the inner shaft is independent from cessation of rotation of the outer shaft.Type: GrantFiled: May 20, 2022Date of Patent: October 10, 2023Assignee: K2M, Inc.Inventors: Steven Ludwig, Scott Dhupar, Sabatino Bianco, Khalid Abbed, Egon Doppenberg, Jennifer Moore, John Donohoe, Scott A.

Patent number: 11344426Abstract: A spinal fixation device includes a housing defining a chamber and a longitudinal axis, and an end plate assembly operatively coupled with the housing. The end plate assembly includes a first end plate configured to engage a vertebral body and first and second support assemblies operatively coupled to the first end plate. The first support assembly is selectively movable between a first position in which the first end plate is spaced apart from the housing and a second position in which the first end plate is adjacent the housing. The second support assembly is transitionable between a first state in which the first end plate has a first angular orientation and a second state in which the first end plate has a second angular orientation.Type: GrantFiled: May 17, 2019Date of Patent: May 31, 2022Assignee: K2M, Inc.Inventors: Todd Wallenstein, Clint Boyd

Publication number: 20220039967Abstract: A spinal fixation device includes an outer housing and an end plate assembly coupled with the outer housing. The outer housing defines an aperture and a longitudinal axis. At least a portion of the end plate assembly is slidably received within the outer housing. The end plate assembly includes a first end plate configured to engage a vertebral body, wherein the end plate assembly is selectively movable between a first position in which the first end plate is spaced apart from the outer housing and a second position in which the first end plate is adjacent the outer housing. Further, the first end plate is selectively adjustable to an angular orientation of a plurality of angular orientations with respect to the longitudinal axis of the outer housing.Type: ApplicationFiled: October 19, 2021Publication date: February 10, 2022Inventors: Chester Evan Sutterlin, III, Ehud Mendel, Michael Finn, Clint Boyd, Scott Jones, Todd Wallenstein, Jacob M.

Publication number: 20200138494Abstract: A bone screw for attaching a spinal prosthetic or bone plate to bone includes a tubular body having open proximal and distal ends. The open proximal and distal ends define a passageway therethrough. A shaft is insertable into the passageway and includes a distal tip that extends beyond the open distal end. The shaft is insertable through a lumen of a head of the bone screw. A gap is defined between a distal surface of the head and a proximal end of the tubular body. The shaft is rotationally fixed with the tubular body and the head. The head is repositionable with respect to the shaft such that an acute angle is defined between the head and a longitudinal axis of the shaft.Type: ApplicationFiled: September 30, 2019Publication date: May 7, 2020Inventors: Todd Wallenstein, Megan Carnes, John Donohoe
