Patent Images
1. An anulus augmentation device for reinforcing an intervertebral disc comprising:
- a support member comprising a mesh frame;
wherein said mesh frame comprises a “
C”
cross-sectional shape extending along a vertical axis;
wherein said mesh frame is elongated along a horizontal axis having a first and second end;
wherein said mesh frame comprises a plurality of flexible interconnected curvilinear members,wherein said plurality of flexible interconnected curvilinear members are adapted to provide flexibility and resilience to said mesh frame;
a membrane, wherein said membrane covers at least a portion of said mesh frame; and
a bow-like anterior stabilizing projection coupled to both ends of said support member,wherein said bow-like projection extends at an angle from about 30-150 degrees relative to the vertical axis of the support member; and
wherein the bow-like projection is configured to prevent migration around the circumference of an intervertebral disc.
