20080249623 | Implant Restraint Device and Methods - An implant retention device is provided to assist in restraining movement of a nuclear implant and to assist in preventing expulsion of the nuclear implant through an incision portal or defect in the annular wall. In general, the implant retention device blocks or obstructs at least a portion of an opening in the annular wall, thereby keeping the implant from exiting the nuclear space through the annular opening. In one form, the implant retention device comprises an expulsion prevention member positioned adjacent the nuclear implant and configured to transition between a compressed position and an expanded position. In another form, the implant retention device may comprise a mounting portion to be positioned adjacent one of the vertebral bodies, a blocking portion for at least partially obstructing the annular opening, and an end projection at a terminal end of the blocking portion to resist expulsion of the implant through the annular opening. In yet another form, the implant retention device may include an elongate blocking member having annulus connector portions extending from each side of the blocking member for engaging with an annular wall. | 10-09-2008 |
20090076518 | METHOD AND SYSTEM FOR STABILIZING ADJACENT VERTEBRAE - A method of stabilizing adjacent vertebrae including the steps of forming at least one annulotomy in an annulus. At least a portion of the nucleus material is removed through the annulotomy to form a cavity in an intervertebral disc space between the adjacent vertebrae. A reservoir containing a flowable biomaterial is fluidly coupled to the intervertebral disc space. A flowable biomaterial is delivered to the cavity. The delivery of the flowable biomaterial into the intervertebral disc space is controlled in accordance with at least a first operating parameter. The biomaterial is at least partially cured to stabilize the adjacent vertebrae. | 03-19-2009 |
20090240333 | Motion Preserving Artificial Intervertebral Disc Device - A motion preserving implant having first and second bearing members and a biasing member disposed therebetween operable to provide resistance to the translation of the bodies with respect to one another. An intervertebral implant having first and second bearing members, a translatable member, a resilient connection between the translatable member and one of the bearing members to allow for relative motion therebetween and bearing surfaces of the translatable member and the other bearing member to allow complex, natural motion between the bearing members. A spinal implant having upper and lower bodies and an articulation surface that allows for polyaxial articulation and translation through a concave articulation surface having a first radius of curvature and a second radius of curvature in at least one plane, and a convex articulation surface having the first radius of curvature in the same plane. | 09-24-2009 |
20090276053 | Coated Implants - An implantable device which provides structural support for the skeletal system, such as the spine, coated with hydroxyapatite (HA). This invention provides a mechanically and bioactively functional coating of hydroxyapatite (HA) without altering the biocompatibility profile of the poly-ether-ether-ketone (PEEK) substrate. | 11-05-2009 |
20100179595 | Intervertebral Implant Devices and Methods for Insertion Thereof - Implant apparatuses are provided for being inserted between adjacent vertebral bone portions and maintaining mechanical engagement with the vertebral bone portions. The implant apparatuses are generally constructed to be inserted in an insertion orientation and pivoted between the vertebral bone portions to an implanted orientation. The implant apparatuses are further secured in the implanted orientation to maintain engagement with the adjacent vertebral bone portions. | 07-15-2010 |
20110106163 | Interlaminar Stabilizing System - A spinal stabilization system includes a first engagement member and a support structure. The first engagement member is adapted to be disposed between a first vertebra and a second vertebra. The engagement member generally includes a seating surface for accommodating at least a portion of a laminar region of the first vertebra. The support structure engages a portion of the second vertebra. The structural cooperation of the first engagement member and the support structure is such that the engagement member restricts reduction of the intervertebral spacing between the first and second vertebrae. | 05-05-2011 |
20120203344 | SYSTEM AND METHODS FOR INSERTING A SPINAL DISC DEVICE INTO AN INTERVERTEBRAL SPACE - A system for replacing a natural nuclear disc in an intervertebral space has a spinal device configured for placement in the intervertebral space. An insertion tool is configured for holding the spinal device while the spinal device is inserted into the intervertebral space. A gripping member of the insertion tool has an end for adjustably holding the spinal device within the intervertebral space. A steering actuator of the insertion tool is operably connected to the spinal device and configured for pivoting the adjustably held spinal device within the intervertebral space while the steering actuator is controlled remotely from the intervertebral space. | 08-09-2012 |
20120310287 | Artificial Disc Device - An artificial disc device for replacing a damaged nucleus is disclosed. In one form, the device may be inserted in components such that the device may be assembled within and retained by the natural annulus therein. In another form, the device may be inserted into the natural annulus in a collapsed or compressed state or arrangement and then be expanded within and retained by the annulus therein. In a further form, the device may be provided with a releasable connection so that the device may be connected in an insertion configuration and may be released in an operable configuration. Insertion tools and methods are also disclosed. | 12-06-2012 |
20140236301 | Systems and Apparatuses for Inserting an Implant in Intervertebral Space - Systems and tools for inserting and securing an implant within the intervertebral space. An intervertebral disc implant with upper and lower bearing members with an articulation interface between the members for providing relative motion therebetween. The implant may be provided with various securing members for fixing the implant within the intervertebral space. A tool may be used to insert the implant, which includes a plurality of shiftable implant engaging members that are shiftable between non-engaging and engaging configurations to alternatively release or hold the implant. | 08-21-2014 |
