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 intervertebral prosthetic device for spinal stabilization and a method of using same according to which a body member is implanted between two adjacent vertebrae so that a spinous process of a vertebra extends into a notch formed in the body member. A groove is also formed in the body member that engages one of the vertebrae. The device is particularly adapted to give support between the sacrum (V6, 14) and the lowest lumbar vertebra (V5).
Abstract:
A system (20, 120, 220) involving anchor retaining mechanisms for a bone plate includes a plate (22, 122, 222) with at least a first hole therethrough between an upper surface and a lower surface of the plate (22, 122, 222) to receive an anchor (26, 226) for engaging a bony segment. The system also includes a partially annular retaining member (28, 128, 228) engageable to the plate (22, 122, 222) and positionable in the hole of the plate (22, 122, 222) to prevent anchor backout while allowing insertion of the anchor (26, 226) through the plate hole and removal of the anchor (26, 226) from the plate hole.
Abstract:
Posterior spinal stabilization devices and methods include first and second elongate elements (28, 30) engageable along the spinal column and a spinous process replacement body (22, 122, 122', 422, 522, 622, 922, 1022, 1122, 1222, 1322, 1422) positionable between the elongate elements (28, 30). Connection mechanisms (24, 26, 124, 126, 324, 326, 526, 528, 744, 746, 1024, 1026, 1124, 1250, 1252, 1340, 1342, 1440, 1442) are provided to adjustably connect the spinous process replacement device to the elongate elements (28, 30) so that the spinous process replacement device can be moved to the desired location between the connecting elements (28, 30) and secured in the desired location.
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:
A spinal implant, implant control device and method of treating a spine are provided. An exemplary spinal implant can include an adjustable component and a connector in communication with the adjustable component, wherein the connector is configured for transcutaneous delivery of an agent to the adjustable component in a manner that affects a condition of the adjustable component.
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:
Instruments and techniques for implanting non-rigid implants (30, 230, 330) are provided that include positively engaging the implant (30, 230, 330) between distal and proximal ends of the implant (30, 230, 330) at least adjacent the distal end of the insertion instrument (10, 60, UO) while deploying the implant (30, 230, 330) longitudinally and distaHy from the insertion instrument (10, 60, 110).
Abstract:
A surgical procedure and device according to which an expandable member is inserted between anatomical structures, and a force is applied to the member in a first plane to cause expansion of the member in a second plane and into engagement with the structures.
