Publication number: 20200129313Abstract: Spinal implant trials are provided having various configurations and sizes that aid the selection of spinal implants having similar configurations and sizes. A surgeon during surgery can insert various configurations and sizes of the spinal implant trials into a disc space between two adjacent vertebral bodies of a patient to enable the selection of a spinal implant configured and sized to fit the patient's disc space. Fluoroscopic images can be used in aiding the selection of an appropriately configured and sized spinal implant corresponding to one of the spinal implant trials. The spinal implant trials include features that reveal on the fluoroscopic images whether the spinal implant trials are properly located and oriented in the disc space and include features corresponding to different sizes of spinal implants also revealed on the fluoroscopic images.Type: ApplicationFiled: December 31, 2019Publication date: April 30, 2020Inventors: Jonathan M. Dewey, William D. Armstrong, Anthony J. Melkent

Patent number: 10575962Abstract: A spinal implant for insertion into a disc space between an upper vertebral body and a lower vertebral body is provided. The spinal implant includes an upper first end plate portion and a lower second end plate portion each extending from at least adjacent a proximal end to a distal end of the spinal implant. The spinal implant is configured to facilitate insertion into the disc space and inhibit withdrawal from the disc space. To the end, the leading end of the spinal implant can be configured to facilitate ease of insertion into the disc space, and an upper surface and a lower surface of the upper first end plant portion and the lower second end plate portion, respectively, can be provided with depressions or dimples forming ridges and points therebetween to inhibit withdrawal from the disc space.Type: GrantFiled: November 20, 2017Date of Patent: March 3, 2020Assignee: Warsaw Orthopedic, Inc.Inventors: Jonathan M Dewey, Anthony J Melkent, William D.

Patent number: 10562172Abstract: Various embodiments of pole devices are described having inner and outer poles or segments that allow for telescoping of the pole device. The inner and outer poles can each include one or more flat side wall portions, which act to thereby prevent rotation of the inner and outer poles with respect to each other. Each of the inner and outer poles can include one or more apertures that are sized to receive a pin to thereby couple the inner and outer poles. One or more gaps may be formed between the inner and outer poles that is sized to receive a burr of at least one of the inner or outer pole.Type: GrantFiled: October 31, 2017Date of Patent: February 18, 2020Assignee: BLUE POINT FASTENERSInventor: William D. Armstrong

Patent number: 10327913Abstract: An interbody implant system is provided. The interbody implant system includes an implant having an engagement surface and an instrument including a first member and a second member that is movable relative to the first member. The first member is configured to capture the implant and the second member includes an interface configured to engage the engagement surface to releasably lock the implant in at least one orientation relative to the second member. The at least one of the engagement surface and the interface include at least one planar face. Methods of use are disclosed.Type: GrantFiled: August 20, 2015Date of Patent: June 25, 2019Assignee: Warsaw Orthopedic, Inc.Inventors: Stanley T. Palmatier, Keith M. Miller, Charles L.

Publication number: 20190091034Abstract: A geared cam expandable spinal implant. Rotational motion of a rotating portion is translated into linear motion of a yoke, which moves geared cams at the distal end of the implant to mate with, and walk along, teeth of corresponding racks. The walking of the gear cam teeth along the rack teeth creates a regular rate of implant expansion, reduces initial excessive expansion force applied to the implant, and provides fine adjustment of the expansion rate and force. Spikes, pivotally mounted on the yoke, pivot outward as the implant expands, to a fully-deployed position into engagement with surfaces of adjacent vertebral bodies. The engagement between the deployed spikes and the vertebral bodies prevents inadvertent backout of the expanded implant.Type: ApplicationFiled: November 26, 2018Publication date: March 28, 2019Inventors: Jonathan Dewey, William D. Armstrong, Anthony J. Melkent

Patent number: 10195050Abstract: An intervertebral implant is provided. The intervertebral implant comprises a first component comprising an outer tissue engaging surface and an inner surface. A second component is connected to the first component, and is relatively moveable therefrom. The second component comprises an outer tissue engaging surface and an inner surface. The second component includes an actuator. A third component is disposed for engagement and is movable relative to the first and second components. The third component comprises at least a first ramp and a second ramp axially spaced apart from the first ramp. The actuator is engageable with the third component to effect axial translation of the wedge such that the ramps engage the inner surface of at least one of the first component and the second component to move the components between a first, collapsed configuration and a second, expanded configuration. Methods of use are disclosed.Type: GrantFiled: September 13, 2016Date of Patent: February 5, 2019Assignee: Warsaw Othopedic, Inc.Inventors: Stanley T. Palmatier, Keith E. Miller, Anthony J.
