Abstract: A system and implant is useful for the minimally invasive closure of dura, bone, and/or ligementous defects. The delivery mechanism allows for the novel deployment of a novel closure device. The implant device with three components, an internal anchor, disc, and retaining ring, is loaded into a delivery system that allows minimally invasive closure and/or reconstruction of anatomical defects. Specifically, the device is designed to be released from the delivery system into narrow spaces of anatomical structures created during surgery. Inner and outer members are connected and locked together in situ which allows for additional anatomical manipulations to take place as required for reconstruction and closure. This allows each component, particularly the inner member, to be tailored to the anatomy.
