Patent application number | Description | Published |
20090177285 | Devices and techniques for a posterior lateral disc space approach - This invention relates to devices and instruments for implant insertion through a posterior lateral opening to the disc space. The instruments include an implant inserter, and the devices include a spinal fusion implant engageable by the implant inserter. The implant provides bilateral support of the adjacent vertebrae when inserted into the disc space from a postero-lateral approach. | 07-09-2009 |
20100004752 | Vertebral body and disc space replacement devices - A vertebral replacement device for supporting adjacent vertebrae includes a vertebral body member having at least one of an upper or lower disc replacement member engaged thereto at one end thereof. The disc replacement device can be positioned in a spinal disc space when disengaged from the vertebral body member. | 01-07-2010 |
20100087875 | Anterior impacted bone graft and driver instruments - Instrument and implants are disclosed which provide for insertion of an implant into an intervertebral disc space from multiple approaches to the spine. Specifically, as a preferred aspect of the invention the implant includes a tapered portion and the implant may be inserted from multiple approaches to the spine with the orientation and taper properly oriented in the disc space regardless of the approach. | 04-08-2010 |
20100249792 | Instruments and techniques for separating bony structures - Instruments and techniques separate or spread adjacent bony structures by inserting a distal spreader assembly into the space between the adjacent bony structures and actuating the spreading members with a proximal actuator assembly. | 09-30-2010 |
20110218633 | DEVICES AND TECHNIQUES FOR A POSTERIOR LATERAL DISC SPACE APPROACH - This invention relates to devices and instruments for implant insertion through a posterior lateral opening to the disc space. The instruments include an implant inserter, and the devices include a spinal fusion implant engageable by the implant inserter. The implant provides bilateral support of the adjacent vertebrae when inserted into the disc space from a postero-lateral approach. | 09-08-2011 |
20110270402 | DEVICES AND TECHNIQUES FOR A POSTERIOR LATERAL DISC SPACE APPROACH - This invention relates to devices and instruments for implant insertion through a posterior lateral opening to the disc space. The instruments include an implant inserter, and the devices include a spinal fusion implant engageable by the implant inserter. The implant provides bilateral support of the adjacent vertebrae when inserted into the disc space from a postero-lateral approach. | 11-03-2011 |
20120109198 | SPINOUS PROCESS IMPLANT WITH A POST AND AN ENLARGED BOSS - A spinous process implant with two plates that are connected together with a post. The implant is configured for each plate to be positioned on outer lateral sides of spinous processes with the post extending through the interspinous space. One or both plates may be movable along the length of the post to accommodate different anatomies such as for relatively wide or thin spinous processes. The post includes an enlarged head at a first end to prevent the first plate from disassociating from the post in a first direction. The post also includes a boss at a second end to prevent the second plate from disassociating from the post in a second direction. Methods of attaching the implants to the spinous processes are also disclosed. | 05-03-2012 |
20120109203 | SPINOUS PROCESS IMPLANT WITH EXTENDED POST - Spinous process implants that may include a first plate sized to extend along a first lateral side of the spinous processes and a second plate sized to extend along a second lateral side of the spinous processes. The second plate may include a bore that extends through the second plate. An elongated post may extend through the bore with a first end attached to the first plate and a second end positioned outward beyond the outer surface of the second plate away from the first plate. A joint may be positioned along the post that attaches a first section of the post to a second section of the post. The joint may be constructed to align the first and second sections in a collinear orientation and to remove the second section from the first section. Additional joints may also be positioned along the post. The bore may be sized relative to the post for the second plate to be movable along a length of the post. | 05-03-2012 |
20120323080 | ADD-ON RETRACTOR ELEMENT FOR RETRACTOR SYSTEM - A retractor assembly for percutaneous surgery in a patient that includes first and second retractor portions positionable opposite one another in an incision of the patient. A working channel extends between the first and second retractor portions and provides access to a location within the patient adjacent to distal ends of the first and second retractor portions. The first and second retractor portions are movable relative to one another to adjust the size of the working channel. An add-on retractor element is provided that is mounted to the first and second retractor portions and spans the gap between the first and second retractor portions to prevent creep of soft tissue into the working channel when the retractor portions are separated. | 12-20-2012 |
20140171946 | SURGICAL INSTRUMENT AND METHOD - A surgical instrument comprises a first member including an inner surface defining a passageway and a lock. A second member is disposable within the first passageway. The second member comprises an inner surface defining a passageway and extending between a first end comprising a lock and a second end configured to engage tissue. A third member is disposable within the second passageway. The third member extends between a first end and a second end configured to penetrate tissue and form a cavity therein. The first lock is engageable with the second member to prevent relative movement of the second member and the second lock is engageable with the third member to prevent relative movement of the third member. Systems and methods are disclosed. | 06-19-2014 |
