DEVICE: iFuse Granite-Closed Head Implant System (00810055522545)

An implantable device designed to be inserted across the sacroiliac joint to provide temporary stabilization and to encourage long-term joint fusion, typically to alleviate pain from the joint. It is made of metal [e.g., titanium (Ti)] with a porous plasma spray coating, and typically in the form of a cylinder or rod, possibly with a triangular cross-section. It is typically surgically implanted under fluoroscopic guidance and may include dedicated disposable implantation instruments.

An assembly of non-sterile implantable devices intended to provide immobilization and stabilization of spinal segments in the treatment of various spinal instabilities or deformities, also used as an adjunct to spinal fusion [e.g., for degenerative disc disease (DDD)]. Otherwise known as a pedicle screw instrumentation system, it typically consists of a combination of anchors (e.g., bolts, hooks, pedicle screws or other types), interconnection mechanisms (incorporating nuts, screws, sleeves, or bolts), longitudinal members (e.g., plates, rods, plate/rod combinations), and/or transverse connectors. Non-sterile disposable devices associated with implantation may be included.
