| 20080255564 | Bone cutting device - Apparatus and a method of inserting spinal implants is disclosed in which an intervertebral space is first distracted, a hollow sleeve having teeth at one end is then driven into the vertebrae adjacent that disc space. A drill is then passed through the hollow sleeve removing disc and bone in preparation for receiving the spinal implant which is then inserted through the sleeve. | 10-16-2008 |
| 20080287955 | Distractor for use in spinal surgery and method of use thereof - Apparatus and a method of inserting spinal implants is disclosed in which an intervertebral space is first distracted, a hollow sleeve having teeth at one end is then driven into the vertebrae adjacent that disc space. A drill is then passed through the hollow sleeve removing disc and bone in preparation for receiving the spinal implant which is then inserted through the sleeve. | 11-20-2008 |
| 20090088857 | Implant for the delivery of electrical current to promote bone growth between adjacent bone masses - An electrical bone growth promotion apparatus for the delivery of electrical current to an implant surgically implanted between adjacent bone masses to promote bone growth to areas adjacent to the implant is disclosed. The apparatus of the present invention comprises a self contained implant having a surgically implantable, renewable power supply and related control circuitry for delivering electrical current directly to the implant and thus directly to the area in which the promotion of bone growth is desired. The desired areas of bone growth promotion may be controlled by conducting negative charge only to the desired location of bone growth promotion. | 04-02-2009 |
| 20100217394 | Frusto-conical spinal implant - The present invention is directed to a variety of interbody spinal fusion implants having at least a partially frusto-conical configuration. The spinal fusion implants of the present invention may be relatively solid or hollow and may have surface roughenings to promote bone ingrowth and stability. The spinal fusion implants of the present invention may have wells extending into the material of the implant from the surface for the purpose of holding fusion promoting materials and to provide for areas of bone ingrowth fixation. A variety of surface irregularities may be employed to increase implant stability and implant surface area, and/or for the purpose of advancing the spinal fusion implant into the fusion site. | 08-26-2010 |
| 20110004310 | Lordotic interbody spinal fusion implants - The present application is directed to interbody spinal fusion implants having a structural configuration that provides for the maintaining and creating of the normal anatomic angular relationship of two adjacent vertebrae of the spine to maintain and create spinal lordosis. The spinal fusion implants are sized to fit within the disc space created by the removal of disc material between two adjacent vertebrae and conform wholly or in part to the disc space created. The spinal fusion implants of the present invention have upper and lower surfaces that form a support structure for bearing against the end plates of the adjacent vertebrae. The upper and lower surfaces are disposed in a converging angular relationship to each other such that the implants have an overall “wedged-shape” in an elevational side view. The angular relationship of the upper and lower surfaces places and maintains the vertebrae adjacent to those surfaces in an angular relationship to each other, creating and maintaining the desired lordosis. | 01-06-2011 |
| 20110054529 | THREADED INTERBODY SPINAL FUSION IMPLANT - The present invention is directed to a variety of interbody spinal fusion implants having at least a partially frusto-conical configuration. An external thread is employed to increase implant stability and implant surface area, and for the purpose of advancing the spinal fusion implant into the fusion site. The spinal fusion implants of the present invention may be relatively solid or hollow and may have surface roughenings to promote bone ingrowth and stability. The spinal fusion implants of the present invention may have wells extending into the material of the implant from the surface for the purpose of holding fusion promoting materials and to provide for areas of bone ingrowth fixation. | 03-03-2011 |
| 20110137420 | EXPANDABLE PUSH-IN ORTHOPEDIC IMPLANT - A push-in orthopedic implant having an expandable height. The implant includes an upper member, a lower member, and a blocker pivotally attached to one of the upper and lower members. The blocker is attached proximate one of the proximal and distal ends of the one of the upper and lower members, and is adapted to pivot into cooperative engagement with another of the one of the upper and lower members. The blocker is adapted to hold at least a portion of the upper and lower members apart so as to maintain an increased height of the implant and resist the collapse of the implant to a collapsed implant height when the implant is in a final deployed position. | 06-09-2011 |
