Abstract:
Systems and methods for positioning a connecting element adjacent an anatomical structure in minimally-invasive surgical procedures, including an electronic guidance system associated with the connecting element and at least one receiving portion of a tissue anchor that receives the connecting element in the patient. The electronic guidance system includes a processor subsystem to receive signals from the guidance system and provide relative positional data between the connecting element and the at least one receiving portion to aid the surgeon in guiding the connecting element to the receiving portion. In one embodiment, the systems and methods are used in association with positioning a connecting element adjacent the spinal column in minimally-invasive spinal stabilization procedures.
Abstract:
A system for treating a spinal condition includes an anterior spinal motion device (54) for an anterior region of a motion segment associated with the pair of vertebrae and a posterior motion preservation device (56,58) for a second region of the motion segment. The anterior spinal motion device may include an elastic material or a motion preserving disc prosthesis having at least one articulating surface.
Abstract:
An implant is disclosed and can include a body and a plurality of pellets disposed within the body. The implant can be moved between an unmolded, relaxed configuration wherein the body is not conformed to a bone and a molded, relaxed configuration wherein the body is at least partially conformed to the bone.

Abstract:
An intervertebral process brace is disclosed and can include a frame that, can support a first vertebral process (500) and a second vertebral process (502). The intervertebral process brace (400) can also include a vertebral process support strap (414) that can span a portion (404) of the frame. The vertebral process support strap can engage the first vertebral process and bind the first vertebral process between the vertebral process support strap and the portion of the frame. The vertebral process support strap may be movable relative to the frame to increase a distance between the first vertebral process and the second vertebral process.
Abstract:
An interspinous process brace is disclosed and can include a superior component and an inferior component. The superior component can include a superior spinous process bracket that can engage a superior spinous process. The inferior component can include an inferior spinous process bracket that can engage an inferior spinous process. Further, the interspinous process brace can be moved between a bent configuration and a straight configuration. In the bent configuration, an overall height of the interspinous process brace can be minimized to facilitate installation between the superior spinous process and the inferior spinous process.
Abstract:
An implant assembly (30, 130) for stabilizing a spinal motion segment includes a flexible spacer member (32, 132) positionable between adjacent transverse processes.

Abstract:
An adjustable interspinous process brace is disclosed and can include a superior component. The superior component can include a superior spinous process bracket that can engage a superior spinous process. Further, the adjustable interspinous process brace can include an inferior component. The inferior component can include an inferior spinous process bracket that can engage an inferior spinous process. Further, the inferior component can be movably engaged with the superior component from a retracted position to an extended position. In the extended position, a distance between the superior spinous process bracket and the inferior spinous process bracket can be increased.
Abstract:
A surgical implantation procedure and a device for performing same according to which an expandable member is inserted between anatomical structures and expanded in one plane to cause relative movement between the structures. The expansion is terminated when the structures are in a predetermined spatial relationship.
