Abstract

The present disclosure concerns implants to at least partially replace the nucleus of a spinal disc. In one embodiment, a prosthetic implant is provided which includes a bag structure (100, 200, 400, 1120) having a fixation component or member (130, 240, 1110), the bag (100, 200, 400, 1120) operable to contain at least one internal implant (410, 1000) within the bag (100, 200, 400, 1120). In other embodiments, a bag structure (1120) is provided, with a flange (1140) adaptable to anchor the structure (1120) to a vertebral body, and a sinusoidal- shaped structure (1005) made of a flexible material is provided with various unique configurations. In one embodiment, for delivery, a bag structure (1120) with a flange (1140) may be attached to a vertebral body. In another embodiment, a sinusoidal-shaped implant structure (1005) is alternately woven from one end to the other with a second sinusoidal- shaped structure (1005).
