Patent number: 12403014Abstract: A variable lordosis endplate that may adjusted from 0 to 30 degrees using a mechanical drive that allows the spine's angle to be physically adjusted in-situ. The variable lordosis endplate may be quickly attached to either end, or both ends, of the central column. The variable lordosis endplate can be attached in orientations of every 15 degrees. The variable lordosis endplates' lordotic angles may be on either end of the column independently from one another. By attaching a variable lordosis endplate to both ends of the column, hyper-lordotic angles may be achieved.Type: GrantFiled: October 10, 2023Date of Patent: September 2, 2025Assignee: Astura Medical Inc.Inventors: Ross Dusterhoft, Thomas Purcell

Patent number: 12357349Abstract: An En Bloc connector configured to couple with multiple sequential reducers or extenders, such as spinal screw reducers, to correct a rotation deformity of the spine by turning or rotating the deformed spine structure toward a normal position. In the embodiments shown, the En Bloc connector holds three sequential reducers in the retracted configuration and four sequential reducers in the extended configuration.Type: GrantFiled: November 17, 2022Date of Patent: July 15, 2025Assignee: ASTURA MEDICAL INC.Inventors: Ross Dusterhoft, Thomas Purcell

Patent number: 12193715Abstract: The present invention is directed to a rod reducer that is both a lateral rod reducer and an axial rod reducer that uses an entirely different mechanism never before used for lateral rod reduction. The lateral rod reducer is configured to move a spinal fixation rod that is not aligned with the pedicle screw to a position above the tulip slot or U-shaped channel. Once in position, the lateral rod reducer also provides an axial rod reducer to advance the spinal fixation rod axially into the tulip slot. Splitting the reducer body geometry to create a hinged jaw that is then driven by a linkage system is novel. The lateral rod reducer of the present invention allows for incremental lateral reduction that utilizes a threaded linkage feature for increased power/mechanical advantage when laterally reducing. This will allow for new techniques of lateral rod manipulation in deformity cases.Type: GrantFiled: November 4, 2022Date of Patent: January 14, 2025Assignee: ASTURA MEDICAL INCInventors: Ross Dusterhoft, Thomas Purcell

Patent number: 11980398Abstract: A crosslink mechanism features a locking clip with interlocking teeth. When being deployed, the surgeon will compress the spring loaded clips, freeing rotation on both sides of the mechanism. Once clipped onto the sequential reducers, the surgeon releases the clips allowing the spring to lock the teeth and therefore lock rotational freedom out of the mechanism.Type: GrantFiled: November 17, 2022Date of Patent: May 14, 2024Assignee: ASTURA MEDICAL INCInventors: Ross Dusterhoft, Thomas Purcell

Publication number: 20230301690Abstract: The present invention is directed to a reducer remover to uncouple or unlock a reducer from a tulip of a pedicle screw. To remove the reducer from the tulip, a reducer remover is inserted onto the reducer to engage and unlock the locking mechanism of the reducer. The reducer remover features a ram that extends distally and engages actuating members to move the actuating members outward. The outward movement of the actuating members engages the locking mechanism to disengage or unlock the reducer from the tulip. In one embodiment, the outward movement of the actuating members push on the reducer clips in an outward direction to disengage them from the tulip. If needed, the ram continues movement distally until contacting the rod or set screw within the tulip. This distal movement of the ram pushes the reducer off of the tulip, making the reducer easy to remove from the tulip.Type: ApplicationFiled: March 24, 2023Publication date: September 28, 2023Applicant: Astura Medical Inc.Inventors: Ross Dusterhoft, Thomas Purcell
