Intended Use

Grafton™ DBM and Grafton Plus™ DBM Paste are intended for use as a bone graft extender, bone graft substitute, and bone void filler in bony voids or gaps of the skeletal system (i.e., posterolateral spine, intervertebral disc space (excluding Flex or Crunch), pelvis and extremities) not intrinsic to the stability of the bony structure. The voids or gaps may be surgically created defects or defects created by traumatic injury to the bone. When used in intervertebral body fusion procedures, Graft™ DBM (excluding Flex or Crunch) and Grafton Plus™ DBM Paste must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler. Grafton™ DBM and Grafton Plus™ DBM Paste are absorbed/remodeled and replaced by host bone during the healing process. Magnifuse™ Bone Graft is intended for use as a bone graft substitute in bony voids or gaps of the skeletal system (i.e., posterolateral spine, intervertebral disc space, pelvis and extremities) not intrinsic to the stability of the bony structure. Voids or gaps may be surgically created defects or defects created by traumatic injury to the bone. Magnifuse™ Bone Graft may be used in a manner comparable to autogenous bone or allograft bone. Magnifuse™ Bone Graft may be mixed with fluid such as bone marrow aspirate, blood, sterile water, or sterile water in order to adjust consistency and handling of bone graft material. When used in intervertebral body fusion procedures, Magnifuse™ Bone Graft must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler. Magnifuse™ Bone Graft is resorbed/remodeled and is replaced by host bone during the healing process.

Device Story

Human bone allograft products containing demineralized bone matrix (DBM); Magnifuse™ includes surface demineralized cortical bone chips in absorbable mesh pouch. Used as bone graft substitute/extender in orthopedic/spinal procedures; fills bony voids/gaps not intrinsic to structural stability. Applied intraoperatively by surgeons; may be mixed with bone marrow aspirate, blood, or sterile fluids to adjust handling. Resorbed/remodeled by host bone during healing. Provides osteoconductive scaffold to facilitate bone repair; supports fusion when used with cleared intervertebral body fusion devices.

Clinical Evidence

No new clinical data. Performance supported by previously cleared submissions (K051195, K043048, K082615) covering DBM characterization, viral inactivation, shelf-life, biocompatibility, and bench performance. Efficacy in intervertebral body space supported by analysis of bone grafting materials in prior posterolateral spine fusion studies.

Technological Characteristics

Human demineralized bone matrix (DBM) based allografts. Magnifuse™ includes surface demineralized cortical bone chips in an absorbable mesh pouch. Grafton™ DBM and Grafton Plus™ include inert additives for handling. Resorbable, single-use, ready-to-use form factors.

Indications for Use

Indicated for patients requiring bone graft substitution or void filling in skeletal defects (posterolateral spine, intervertebral disc space, pelvis, extremities) not intrinsic to structural stability. Applicable to surgically created or traumatic defects. Must be used with FDA-cleared intervertebral body fusion devices for spinal fusion procedures.

Grafton™ DBM is provided in ready-to-use form and is intended in Grafton™ DBM, Grafton Plus™ DBM Paste, Magnifuse™ Bone Graft Page 1 of 3 {5} Medtronic Engineering the extraordinary K251193 single patient, single use containers. Grafton™ DBM is identical to the device cleared in K051195. Grafton Plus™ DBM Paste is human demineralized bone matrix (DBM) combined with an inert additive to yield a product having a particular physical form and/or handling property. Grafton Plus™ DBM Paste is identical to the device cleared in K043048. Magnifuse™ Bone Graft is a human bone allograft product containing human DBM and surface demineralized cortical bone chips sealed in an absorbable mesh pouch for intraoperative handling. It is intended for use in filling bony voids or gaps or the skeletal system not intrinsic to the stability of the bony structure. Magnifuse™ Bone Graft is provided ready-to-use in various package sizes by volume or dimension and is intended for single patient use. Magnifuse™ Bone Graft is identical to the device cleared in K082615. # Indications for Use Statement Grafton™ DBM and Grafton Plus™ DBM Paste are intended for use as a bone graft extender, bone graft substitute, and bone void filler in bony voids or gaps of the skeletal system (i.e., posterolateral spine, intervertebral disc space (excluding Flex and Crunch), pelvis, and extremities) not intrinsic to the stability of the bony structure. The voids or gaps may be surgically created defects or defects created by traumatic injury to the bone. When used in intervertebral body fusion procedures, Grafton™ DBM (excluding Flex and Crunch) and Grafton Plus™ DBM Paste must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler.

The intended use is the same for subject and predicate devices, which are cleared for use in intervertebral disc space. There are differences in the devices’ material composition, but this does not raise different questions of safety and effectiveness. The effect of differences in material composition is addressed in the prior functional animal model performance. ## Performance The subject devices have been previously cleared under K051195, K043048, K082615, which serve as Reference Devices. These submissions are leveraged to support the devices’ DBM, viral inactivation, shelf-life, endotoxin, pyrogenicity, biocompatibility, and characterizations/bench performance. The devices’ performance in the intervertebral body space was supported by a robust analysis of bone grafting materials in the prior posterolateral spine fusion studies. ## Summary The subject devices and predicates have the same intended use, and the same specific indications for use in the intervertebral disc space of the spine. Any differences in technological characteristics between the subject devices and predicate do not raise different questions of safety and effectiveness. Based on the clinical analysis, Medtronic concludes that the devices are substantially equivalent to the predicates. Grafton™ DBM, Grafton Plus™ DBM Paste, Magnifuse™ Bone Graft Page 3 of 3
