Patent number: 10441327Abstract: The instruments and methods of the present disclosure include an outer shaft, an inner shaft, a roller, and an actuator. In some examples, the outer shaft includes a lumen extending from a proximal end to a distal end. The inner shaft is disposed within the lumen. The roller rotatably is coupled with the distal end at an axis and configured to engage the fixation rod. The actuator operably couples with the inner shaft to translate the inner shaft within the lumen and cause rotation of the roller to impart linear movement on the fixation rod.Type: GrantFiled: June 19, 2017Date of Patent: October 15, 2019Assignee: Alphatec Spine, Inc.Inventors: Nathan Meyer, Martin Bouliane, Wally Gillespie, Anand Parikh, Jens Peter Timm

Patent number: 10398480Abstract: A polyaxial screw head remobilizer system for remobilizing a screw body member relative to a head of a polyaxial bone screw includes a barrel body, a handle assembly, an inner shaft, a slide assembly, and a lever. The barrel body includes proximal and distal ends. The distal end includes a plurality of prongs for releasably engaging a plurality of yokes of the polyaxial screw body member to center the inner shaft over the head of the screw. The handle assembly couples to the proximal end of the barrel body. The inner shaft, disposed within the barrel body, includes proximal and distal ends. An engagement feature of the inner shaft mates with pockets of a bushing of the screw body member. The slide assembly is operably coupled to the barrel body and effect translations of the inner shaft. The lever extends from the slide assembly and rotates to actuate the slide assembly.Type: GrantFiled: July 8, 2016Date of Patent: September 3, 2019Assignee: Alphatec Spine, Inc.Inventors: Tara Stevenson, Wally Gillespie, Clark Hutton

Patent number: 10070900Abstract: An instrument for obtaining spinal rod measurements in situ includes a measurement member, a first indicating member, and a second indicating member. The measurement member measures a length between two spinal implants. The first indicating member couples with the measurement member and includes a first measurement scale coupled with a first shaft for engaging a first spinal implant of the two spinal implants. The second indicating member couples with the measurement member and includes a second measurement scale coupled with a second shaft for engaging a second spinal implant of the two spinal implants.Type: GrantFiled: September 21, 2015Date of Patent: September 11, 2018Assignee: Alphatec Spine, Inc.Inventors: S. Kyle Hayes, Wally Gillespie

Patent number: 9844400Abstract: An instrument for provisionally tightening a screw body member to a head of a polyaxial bone screw includes a barrel body, an inner shaft, a handle and lever, and a load link assembly. The barrel body includes a distal end with a pair of rotatable tangs configured to engage the screw body member. The inner shaft includes a distal end configured to engage a bushing within the screw body member. The lever pivotally couples to one of the handle and the barrel body. The load link assembly couples to the inner shaft and the lever. Actuation of the lever towards causes the load link assembly to longitudinally displace the inner shaft toward the distal end to contact the bushing and advance the bushing into frictional fit between the screw body member and the head of the polyaxial bone screw.Type: GrantFiled: October 18, 2013Date of Patent: December 19, 2017Inventors: Tara Stevenson, Wally Gillespie, Clark Hutton

Patent number: 9561062Abstract: A system for reducing deformities in the spine includes a first tower assembly and a second tower assembly. The first tower assembly includes a first tower that couples to a first screw in a first vertebral level, a load transfer ring rotatable coupled to the first tower, and a load transfer link rotatably coupled to the load transfer ring. The second tower assembly includes a second tower that couples to a second screw in a second vertebral level, a load applicator secured to the second tower, and a load transfer member rotatably coupled to the second tower and linked to the load transfer link. The load applicator applies force to the load transfer member to position the first tower assembly relative to the second tower assembly.Type: GrantFiled: March 15, 2013Date of Patent: February 7, 2017Assignee: ALPHATEC SPINE, INC.Inventors: Kyle Hayes, Wally Gillespie

Patent number: 9468474Abstract: An instrument for correction of spinal deformities includes an inner member with a proximal portion configured to receive a corrective force and a distal coupling portion configured to transfer the corrective force to a spinal implant in a vertebra. A slot extends transversely through the coupling portion and is configured to guide a fixation rod into the spinal implant. A threaded sleeve includes an external thread and a thru-bore that slides relative to the proximal portion. An outer member couples with the proximal portion and threadably engages the external thread to apply a reduction force as the outer member rotates relative to the inner member. A reduction blade includes a proximal interlocking portion that removably couples with the threaded sleeve and a distal rod engagement feature configured to engage the fixation rod and transfer the reduction force to reduce the fixation rod into the spinal implant.Type: GrantFiled: February 28, 2014Date of Patent: October 18, 2016Assignee: Alphatec Spine, Inc.Inventors: Anand Parikh, Garrett Gleeson, Carmen Walters, Jens Peter Timm, Jonathan Costabile, Wally Gillespie, Clark Hutton
