MagnetOs MIS is intended to fill bony voids or gaps of the skeletal system, i.e., the extremities, pelvis, intervertebral disc space, and posterolateral spine. The osseous defects may be surgically created or the result of traumatic injury to the bone and are not intrinsic to the stability of the bony structure. In the extremities, pelvis, intervertebral disc space and posterolateral spine, MagnetOs MIS may be used standalone or with autograft as a bone extender. When used in intervertebral body fusion procedures, MagnetOs MIS must also be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler.
MagnetOs MIS resorbs and is replaced with bone during the healing process.
MagnetOs MIS includes a synthetic, resorbable, osteoconductive bone void filler for the repair of bony defects. MagnetOs MIS graft material is a mixture of ceramic granules premixed with a synthetic polymeric binder that provides cohesion between the granules. The ceramic portion of MagnetOs MIS consists of 65–75% tri-calcium phosphate (TCP – Ca3(PO4)2) and 25–35% hydroxyapatite (HA – Ca10(PO4)6(OH)2) granules.
While the polymeric binder is rapidly resorbed after implantation, the granules of MagnetOs MIS guide the three-dimensional regeneration of bone in the defect site into which it is implanted. New bone will be deposited on the surface of the graft when placed next to viable host bone. The graft resorbs and is replaced by bone during the natural process of bone remodeling.
MagnetOs MIS graft material is provided in a 5cc pre-filled cartridge, packed together with a delivery system kit in a ready-to-use format. The MagnetOs MIS delivery system allows users to apply the bone graft into the defect. MagnetOs MIS is gamma-sterilized and sterile packaged for single use only.
Based on the provided FDA 510(k) clearance letter for MagnetOs MIS, the device is a bone void filler, which is a Class II medical device. The information details the device's characteristics and its substantial equivalence to predicate devices, primarily based on design, materials, and existing data from previously cleared products.
However, the provided document does not contain any information about acceptance criteria and a study that proves the device meets those criteria, specifically regarding AI/ML performance, diagnostic accuracy, or human reader improvement. The document focuses on the physical and material properties of the bone void filler and its delivery system, along with regulatory compliance related to device classification and manufacturing.
Therefore, I cannot fulfill your request to describe the acceptance criteria and the study proving the device meets them in the context of AI/ML performance, ground truth, expert adjudication, or MRMC studies. The document explicitly states: "No additional animal performance or clinical data was provided to support substantial equivalence for the proposed indications. Instead, animal and clinical data from previous clearances of the additional predicate devices were leveraged to support the current submission, as recommended in the FDA's Class II Special Controls Guidance document for Resorbable Calcium Salt Bone Void Filler Devices."
This indicates that the clearance was based on demonstrating the new device's material and design equivalence to already cleared devices, rather than new clinical or AI performance studies for this specific submission.
If you have a different document or would like to provide more context about an AI/ML component related to a similar device, please do so, and I would be happy to analyze it.
§ 888.3045 Resorbable calcium salt bone void filler device.
(a)
Identification. A resorbable calcium salt bone void filler device is a resorbable implant intended to fill bony voids or gaps of the extremities, spine, and pelvis that are caused by trauma or surgery and are not intrinsic to the stability of the bony structure.(b)
Classification. Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Resorbable Calcium Salt Bone Void Filler Device; Guidance for Industry and FDA.” See § 888.1(e) of this chapter for the availability of this guidance.
