20080208344 | Intervertebral Implant Devices and Methods for Insertion Thereof - An implant device is provided that is configured for implantation at multiple locations between adjacent vertebrae. The implant device comprises an implant body, a first portion of the implant body, and a second portion of the implant body adjustably interconnected with the first portion. The implant body has a compact orientation and an extended orientation to allow the implant body to be shifted from one orientation to the other orientation for being positioned in any one of areas between the spinous processes of the adjacent vertebrae, between laminar regions of the adjacent vertebrae, spanning an opening in the annulus between the adjacent vertebrae, and in the intervertebral space between the adjacent vertebrae. | 08-28-2008 |
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 |
20090030457 | Spinal Fixation Systems - A spinal fixation system is provided that includes a coupling member and a locking device that is operable to fix an elongate member relative to the coupling member. In one form, locking device includes opposing lock arms operable to retain the locking device relative to the coupling member in an initial position prior to the locking device fixing the elongate member relative to the coupling member. In another form, the coupling member and locking device include cooperating structure therebetween in the form of a protrusion and a guide track, the cooperating structure arranged and configured to retain the locking device within an internal space of the coupling member. There is also provided a retainer operable to minimize pivoting of the coupling member relative to an anchor member and to substantially retain an anchor member depressed within an internal space of the coupling member to minimize play therebetween. | 01-29-2009 |
20100016974 | SYSTEMS AND METHODS FOR SECURING AN IMPLANT IN INTERVERTEBRAL SPACE - An intervertebral disc implant with upper and lower bearing members with an articulation interface between the members for providing relative motion therebetween. In one form, a securing member with an elongate shaft and a bone-engaging member on the shaft is disposed on one of the bearing members. The bone-engaging member is deployable into a bone-engaging position via rotational displacement of the shaft. In another form, a bone-engaging member is deployable via an actuator inserted into the implant body. In another form, the securing member secures an intervertebral implant in intervertebral space via deformation of the securing member causing a bone-engaging member of the securing member to be deployed into contact with an adjacent vertebra. | 01-21-2010 |
20100042216 | Implant for Deploying Bone Graft Material and Methods Thereof - Invertebral implants are provided for carrying bone graft material and extruding the bone graft material between the implant and the adjacent vertebral bodies. The implants include first and second implant extrusion members shiftable relative to one another between a pre-implantation configuration having an enlarged cavity for receiving bone graft material therein and an implantation configuration having a smaller cavity. As the first and second implant extrusion members shift during implantation to the implantation configuration bone graft material is extruded from the cavity and into gaps or spaces between the upper and lower vertebral engaging surfaces of the implant and the adjacent vertebral bodies. After extrusion the bone graft material is subjected to spinal loading and stress to encourage strong bone growth therethrough. | 02-18-2010 |
20100280619 | SYSTEMS AND METHODS FOR SIZING, INSERTING AND SECURING AN IMPLANT IN INTERVERTEBRAL SPACE - A prosthetic spinal implant having a securing member for fixing the implant relative to an adjacent bone. In one form, the securing member is deployable into a portion of the vertebral space for affixing the implant between the vertebrae. The securing member may be disposed substantially within the body of a bearing member of the implant when the securing member is in an undeployed orientation. In other forms, the securing member is provided separately from the implant such that it may be inserted into the intervertebral space after the implant has been placed in an implanted orientation between the vertebrae. In such forms, the securing member is configured for ease of insertion between an outer bearing surface of the implant and an adjacent bone via linear or rotary motion. | 11-04-2010 |
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 |
20110208311 | Device For Securing An Impalnt To Tissue - An implant device is provided for implantation within an intervertebral space between adjacent vertebrae comprising an implant body, a rotatable portion and a piercing portion configured to pierce the adjacent vertebra. | 08-25-2011 |
20120065690 | Bone Plate System - A bone plate system having a retainer for resisting back-out of a bone anchor from a throughbore of a bone plate is provided. In one aspect, a bone plate system having a resilient retainer disposed in a bone plate throughbore with a pair of elongate arm portions of the resilient retainer extending along opposite sides of the throughbore. In another aspect, a bone plate system having a resilient retainer with a pair of elongate interference portions completely exposed in the throughbore and spaced from each other across the throughbore to retain a head of a bone anchor received in the throughbore. In addition, a bone plate system having a resilient retainer with a pair of opposite end portions disposed within a groove of a throughbore wall such that a bone anchor may be inserted into the throughbore without contacting either of the opposite end portions of the retainer. | 03-15-2012 |
20120209332 | Spinal Fixation System And Method - A spinal fixation system is provided that, in one form, comprises a pedicle screw assembly having a coupling device with an elongate member for guiding a fixation element, such as a spinal rod, into the coupling device and a lock device for fixing the spinal rod to the coupling device. The pedicle screw assembly may be passed through a small incision and connected to a vertebral bone. By connecting a second pedicle screw assembly to a second vertebral bone, the elongate members of the pedicle screw assemblies provide guideposts for directing the spinal rod subcutaneously between the pedicle screw assemblies and into the coupling devices thereof. | 08-16-2012 |
20140180418 | Device For Securing An Implant To Tissue - An implant device is provided for implantation within an intervertebral space between adjacent vertebrae comprising an implant body, a rotatable portion and a piercing portion configured to pierce the adjacent vertebra. | 06-26-2014 |
