Patent number: 9204905Abstract: A system for replacing at least a portion of a natural facet joint includes a fixation member implantable in a vertebra, an inferior facet articular surface and an inferior strut which may be formed separately from the inferior articular surface. The inferior strut has a first end securable to the fixation member and a second end which may comprise a sphere with a hemispherical surface. An attachment mechanism may include a capture feature shaped to receive the second end of the inferior strut, and the mechanism may provide an adjustable configuration, allowing polyaxial adjustment between the inferior articular surface and the second end. A locking member may be actuated to exert force on the second end to provide a locked configuration. The system may further include a superior facet joint implant with a superior articular surface shaped to articulate with the inferior articular surface.Type: GrantFiled: May 24, 2012Date of Patent: December 8, 2015Assignee: GMEDELAWARE 2 LLCInventor: Andrew R. Fauth

Patent number: 9198675Abstract: A surgical rasping and/or shaving system functions in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system may comprise a tissue removal member with a rasping and/or shaving head which may be low profile and offer a flat cutting/rasping/shaving surface, or with a cutting head with at least one cutting edge. The tissue removal member is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion. Suction for removal of bone fragments or other tissues is provided through an opening spaced apart from or adjacent to the rasping surface. A radiofrequency ablation (RF) electrode may be carried on the system to provide ablation or coagulation of soft tissues.Type: GrantFiled: April 18, 2013Date of Patent: December 1, 2015Assignees: IMDS LLCInventors: Keith J.

Publication number: 20150297263Abstract: A facet joint replacement system includes an inferior implant with an inferior articular surface, and a superior implant with a superior articular surface. The implants may be coupled together by a detachable coupler which can align and rigidly hold the inferior and superior articular surfaces in a preferred alignment relative to one another. In one method of implantation, the superior and inferior implants may be aligned and coupled together with the coupler, and then secured to fixation members anchored in adjacent vertebrae. Alternatively, a first implant may be secured to a fixation member anchored in a first vertebra, and a second implant coupled to the coupler, aligned with the first implant and then secured to a fixation member anchored in a second vertebra. A tool may grip, position and/or deliver the coupler and the implants.Type: ApplicationFiled: June 29, 2015Publication date: October 22, 2015Inventors: Daniel J. Triplett, Andrew R. Fauth, Joel R.

Publication number: 20150230826Abstract: A facet joint replacement system includes an inferior implant with an inferior articular surface, a superior implant with a superior articular surface and may include a crosslink extending across a vertebral sagittal plane. The inferior implant may comprise an inferior strut, and a polyaxially adjustable, lockable mechanism which may couple the inferior articular surface with a first end of the inferior strut, and couple the inferior articular surface with the crosslink. A second end of the inferior strut may be secured to a polyaxially adjustable, lockable fixation assembly securable in a vertebra. The superior implant may be secured to a polyaxially adjustable lockable fixation assembly securable in a vertebra. The positions of the inferior articular surface and the first end of the inferior strut are independently translatable along a medial-lateral axis of the vertebra prior to lockout by the lockable mechanism. The crosslink may be placed into the lockable mechanism from a posterior approach.Type: ApplicationFiled: May 4, 2015Publication date: August 20, 2015Inventors: Joel R. Helgerson, Daniel J.

Patent number: 9095382Abstract: A facet joint replacement system includes an inferior implant with an inferior articular surface, and a superior implant with a superior articular surface. The implants may be coupled together by a detachable coupler which can align and rigidly hold the inferior and superior articular surfaces in a preferred alignment relative to one another. A portion of the coupler may be deformable to allow detachment of the coupler from at least one of the implants. In one method of implantation, the superior and inferior implants may be aligned and coupled together with the coupler, and then secured to fixation members anchored in adjacent vertebrae. Alternatively, a first implant may be secured to a fixation member anchored in a first vertebra, and a second implant coupled to the coupler, aligned with the first implant and then secured to a fixation member anchored in a second vertebra.Type: GrantFiled: May 18, 2012Date of Patent: August 4, 2015Assignee: GMEDELAWARE 2 LLCInventors: Daniel J.

Patent number: 8900273Abstract: A fixation system is designed to lock an elongated member within a housing member, permitting positional and/or orientational adjustment of the elongated member prior to locking. The system includes a housing member, a slotted spherical collet, an elongated member, and may include a tapered wedge, which may be a discrete component or formed as part of the elongated member. The housing member and/or elongated member may be implantable. The elongated member may be positioned in the wedge, the wedge in the collet, and the collet in the housing such that when compression force is applied to the wedge and the collet, the wedge contracts about the elongated member and the collet expands to engage the housing, thus locking the elongated member relative to the housing. The collet may have a tapered channel with a degree of taper equal to the tapered wedge. The collet may have multiple slots to allow uniform radial expansion and compression.Type: GrantFiled: January 10, 2008Date of Patent: December 2, 2014Assignee: GMEDelaware 2 LLCInventors: Andrew R.

Publication number: 20140277493Abstract: An inserter instrument and an implant device are provided. An interconnection between an implant and an instrument may include a threaded connection and a gripping connection. Motion of the gripping connection is coordinated with motion of the threaded connection. One implant includes a threaded hole and an adjacent angled pocket, both of which extend into the implant through an instrument-facing surface. One instrument includes a threaded rod and an adjacent pivoting finger, both of which protrude from an end face of the instrument. When the implant is connected to this instrument, the instrument-facing surface abuts the end face, the threaded rod engages the threaded hole, and the finger extends into the pocket along an angle of the pocket.Type: ApplicationFiled: September 30, 2013Publication date: September 18, 2014Applicant: Osteomed LLCInventors: Jason M.
