Abstract: An occlusion device for occluding a defect in a spinal disc anulus, including a plate and a retention device. The plate defines an anulus contact face. The retention device extends from the contact face of the plate and defines an anulus engagement portion. The retention device is deflectable relative to the plate such that in a deployed state, the retention device biases the plate against material disposed between the contact face of the plate and the anulus engagement portion. Upon final deployment, the retention device bears against the exterior surface of the anulus, biasing the plate into contact with the interior surface of the anulus. In a preferred embodiment, the retention device includes a pair of L-shaped arms each extending in an opposing, angular fashion from the plate.

Abstract: An occlusion device for occluding a defect in a spinal disc anulus having interior and exterior surfaces, and defining an internal cavity. The occlusion device includes a first member, a second member, and a connector. The first member is configured for deployment within the internal cavity and placement against the interior surface of the anulus. The second member is configured for placement against the exterior surface of the anulus. Finally, the connector connects the first and second members and is preferably adapted to provide an adjustable spacing therebetween. With this construction, the device is configured such that upon final deployment, the first and second members are rigidly secured against the anulus, at opposite surfaces thereof, in a region of the defect via the connector.
