| 20100036424 | METHODS AND SYSTEMS FOR INCREASING THE BENDING STIFFNESS AND CONSTRAINING THE SPREADING OF A SPINAL SEGMENT - A system for restricting spinal flexion includes superior and inferior tether structures joined by a pair of compliance members. Compliance members comprise tension members which apply a relatively low elastic tension on the tether structures. By placing the tether structures on or over adjacent spinous processes, flexion of a spinal segment can be controlled in order to reduce pain. | 02-11-2010 |
| 20100234890 | SURGICAL TETHER APPARATUS AND METHODS OF USE - A spinal treatment system includes a constraint device having an upper tether portion, a lower tether portion and a compliance member coupled therebetween. The upper tether portion is coupled with a superior spinous process of a spinal segment in a patient and the lower tether portion is coupled with an inferior spinous process or sacrum of the spinal segment. The length or tension in the constraint device is adjustable so that the construct of the tether portions and the compliance member provides a force resistant to flexion of the spinal segment. The system also includes a first prosthesis coupled with the spinal segment, wherein the constraint device modulates loads borne by the prosthesis or by tissue adjacent thereto. | 09-16-2010 |
| 20100234894 | SURGICAL TETHER APPARATUS AND METHODS OF USE - Methods and apparatus for controlling flexion in a spinal segment of a patient include performing a spinal fusion procedure on a pair of adjacent vertebrae in the spinal segment and implanting a constraint device into the patient. Adjusting length or tension in the constraint device allows the constraint device to provide a force a force resistant to flexion of the spinal segment undergoing fusion. The constraint device also modulates loads borne by the spinal segment undergoing fusion or tissue adjacent thereto. | 09-16-2010 |

| 20080262549 | METHODS AND SYSTEMS FOR DEPLOYING SPINOUS PROCESS CONSTRAINTS - An exemplary method for constraining spinous processes to elastically limit flexion of a spinal segment comprises piercing an interspinous ligament to form a first penetration above an upper side of an upper spinous process and advancing a first end of a first tether through the first penetration. The interspinous ligament is pierced again to form a second penetration below a lower side of a lower spinous process and a second end of a second tether is advanced through the second penetration. Joining the first and second tethers together forms an extensible tether structure coupling the upper and lower spinous processes together while permitting extension therebetween. Adjusting the tether structure sets relative distance or angle between the upper and lower spinous processes to a target value. | 10-23-2008 |
| 20080319487 | Methods and Devices for Controlled Flexion Restriction of Spinal Segments - A system for restricting spinal flexion includes superior and inferior tether structures joined by a pair of compliance members. Compliance members comprise tension members which apply a relatively low elastic tension on the tether structures. By placing the tether structures on or over adjacent spinous processes, flexion of a spinal segment can be controlled in order to reduce pain. | 12-25-2008 |
| 20090264929 | STRUCTURES AND METHODS FOR CONSTRAINING SPINAL PROCESSES WITH SINGLE CONNECTOR - Spinous process constraint structures include a first attachment element for placement over a first spinous process and a second attachment element for placement over a second spinous process. The attachment elements are joined by a single connector which may optionally include a compliance member for providing controlled elasticity between the spinous processes. | 10-22-2009 |
| 20090264932 | METHODS AND SYSTEMS FOR CONSTRAINT OF MULTIPLE SPINE SEGMENTS - Methods, apparatus and systems for constraining spinous processes to elastically limit flexion of two or more adjacent spinal segments rely on placing a tether structure over at least three adjacent vertebral bodies or two adjacent vertebral bodies and the sacrum. The tether structures may be continuous, for example in the form of a continuous loop, or may be discontinuous, for example in the form of a loop or elongate element having at least two anchor structures for securing in bone. | 10-22-2009 |

| 20090082820 | SPINAL IMPLANT AND METHOD FOR RESTRICTING SPINAL FLEXION - A spinal implant system for restricting flexion of a spine includes an elongate band proportioned to engage at least two spinous processes. During use, the band is positioned engaging the spinous processes at a spinal segment of interest, where it restricts flexion at the segment. The length and tension of the band may be adjustable following to implantation using percutaneous or transcutaneous means. | 03-26-2009 |
