Patent number: 8551094Abstract: Disclosed is a bone fracture fixation device, such as for reducing and compressing fractures in the proximal femur. The fixation device includes an elongate body with a helical cancellous bone anchor on a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device. The device is rotated into position across the fracture or separation between adjacent bones and into the adjacent bone or bone fragment, and the proximal anchor is distally advanced to apply secondary compression and lock the device into place. The device may also be used for soft tissue attachments.Type: GrantFiled: May 8, 2012Date of Patent: October 8, 2013Assignee: Interventional Spine, Inc.Inventors: Gerard von Hoffmann, Victor V. Cachia, Brad S. Culbert

Publication number: 20120283750Abstract: Methods for repairing a meniscus, and particularly a torn meniscus. A method of repairing a meniscus may include using a suture passer to pass a suturing element from the region between the superior surface of the meniscus and the femoral condyle, through the meniscus tissue, into the region between the inferior surface of the meniscus and the tibial plateau, across the inferior surface of the meniscus, and back to the superior surface of the meniscus, without deeply penetrating the posterior capsular region of the knee. Equivalently, the suture element may be passed from the inferior surface of the meniscus to the superior surface and back to the inferior surface.Type: ApplicationFiled: September 28, 2011Publication date: November 8, 2012Inventors: Justin D. Saliman, Brad S. Culbert, Alexander Jasso, Michael J. Hendricksen, John G. McCutcheon, Chris P. Bender, Michael Murillo

Publication number: 20120215262Abstract: A spinal fixation procedure and system are provided for fixing the spacing of an inferior vertebra relative to a superior vertebra. The procedure for implanting a spinous process spacer can comprise decorticating and/or forming a notch in adjacent spinous processes, measuring the distance between the notches formed in the spinous processes, and inserting an interspinous process implant such that the implant is fitted into the notches of the spinous processes. Other fixation devices, such as bone screws, can also be used for fixing the position of the vertebrae and to create facet fusion.Type: ApplicationFiled: February 16, 2012Publication date: August 23, 2012Applicant: INTERVENTIONAL SPINE, INC.Inventors: Brad S.

Publication number: 20110218575Abstract: Fusion of cervical spinal vertebrae with one or more fixation devices can be accomplished with the described tools and methods. For example, a guidewire introducer can include a tubular introducer cannula and a handle. The handle can be angularly offset from the introducer cannula such that positioning of the introducer on the cervical spine does not interfere with a patient's head. A sheath assembly can include inner and outer sheath bodies and a handle. The handle is angularly offset from the sheath bodies such that the sheath assembly can be applied to the cervical spine without interference to the patient's head. The sheath body can be curved or straight. Various tools such as drills, tapping devices, compression tools, and pin release tools can be applied to the cervical spine through the sheath body to apply the fixation device. The tools can include elongate flexible shafts.Type: ApplicationFiled: April 1, 2011Publication date: September 8, 2011Applicant: INTERVENTIONAL SPINE, INC.Inventors: Brad S.

Publication number: 20100331891Abstract: A system and method of bone fixation are provided for improving the bone growth and stability of the fixated bones. For example, a target site for a bone fixation procedure can be accessed at a facet of a first vertebra using a tissue dilator. Bone material can be disrupting from or at the target site, and a bone fixation device can be installed to fix the first vertebra relative to a second vertebra. The disruption and/or removal of the bone material, such as by rasping facets or a facet joint of the first vertebra and the second vertebra, can tend to promote bone growth. Further, it is contemplated that bone graft material can be inserted at the target site, such as into a joint space formed between facets of the first vertebra and the second vertebra.Type: ApplicationFiled: June 23, 2010Publication date: December 30, 2010Applicant: Interventional Spine, Inc.Inventors: Brad S.

Patent number: 7686807Abstract: A tool for inserting a bone fixation device is provided. The tool generally includes an elongate outer body and an elongate inner body, each having a proximal end, a distal end, and a longitudinal axis. The tool typically includes a pin-receiving portion at the distal end of the outer body for receiving a proximal pin of a bone fixation device. The tool may further include first and second levers pivotally mounted to the inner member at respective pivot axes, and each of the levers having a gripping portion. The levers preferably include finger engagement portions, wire-gripping portions, and are preferably configured to be axially movable relative to the outer body. The levers are generally configured such that a proximal force on the finger engagement portions relative to the outer body will cause the pin engagement portions to close and to move proximally such that a guidewire of a bone fixation device placed between the wire-gripping portions may be gripped and pulled proximally.Type: GrantFiled: March 1, 2004Date of Patent: March 30, 2010Assignee: Interventional Spine, Inc.Inventors: Martin Padget, Brad S.
