MagnetOs Granules is an implant intended to fill bony voids or gaps of the skeletal system, i.e., the extremities, pelvis, intervertebral disc space, and posterolateral spine. These 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.
When used in posterolateral spine, extremities and pelvis, MagnetOs Granules may be used standalone or mixed with autograft, blood, and/or bone marrow. When used in intervertebral body fusion procedures, MagnetOs Granules must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler and hydrated with blood. MagnetOs Granules may also be mixed with autograft.
MagnetOs Granules resorbs and is replaced with bone during the healing process.
MagnetOs Granules is a synthetic, resorbable, osteoconductive bone void filler for the repair of bony defects. MagnetOs Granules consists of 65-75% tri-calcium phosphate (TCP - Ca3(PO4)2) and 25-35% hydroxyapatite (HA - Ca10(PO4)6(OH)2) granules with a porous trabecular structure that resembles the interconnected porosity of human cancellous bone. MagnetOs Granules 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 Granules is a ready-to-use product. MagnetOs Granules is provided in vials in a range of product volumes. MagnetOs Granules is gamma-sterilized and sterile packaged for single use only.
The total interconnecting porosity of MagnetOs Granules is 70 ± 15%. Pore diameters in the scaffold range from 0 to 1000 µm (1mm).
The provided document is a 510(k) summary for a medical device called MagnetOs Granules. It does not describe acceptance criteria for a diagnostic AI/ML device, nor does it contain a study that proves a device meets such criteria. Instead, it details the substantial equivalence of MagnetOs Granules to predicate devices for its intended use as a bone void filler.
Therefore, I cannot extract the information required to answer your query. The document mentions "non-clinical testing data," "animal testing," and a "clinical study" for MagnetOs Granules itself, but these are for demonstrating the safety and effectiveness of a bone void filler for orthopedic application, not for evaluating the performance of an AI/ML diagnostic tool against specific acceptance criteria like sensitivity, specificity, or AUC.
The information you've requested (acceptance criteria table, sample size for test set, expert qualifications, adjudication method, MRMC study, standalone performance, ground truth type, training set size, and training set ground truth establishment) are typical for the evaluation of a diagnostic AI/ML algorithm. This document is related to a different type of medical device (a resorbable calcium salt bone void filler) and does not provide these details.

Dear Hen Baron:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Predicate Device:
Kuros submits the following information in this Premarket Notification to demonstrate that. for the purposes of FDA's regulation of medical devices, MagnetOs Granules is substantially equivalent in indications, design principles, and performance to the following predicate devices, which have been determined by FDA to be substantially equivalent to pre-amendment devices:
Primary Predicate: NuVasive AttraX Putty (K203714) Reference Device: MagnetOs Granules (K213111)
Performance Testing Summary:
The purpose of this submission is to expand the indications for use of the MagnetOs Granules device to include use in the intervertebral disc space in conjunction with an intervertebral body fusion device cleared by FDA for use with a bone void filler.
In support of the prior clearance (K213111), non-clinical testing data were submitted according to the guidance documents Guidance for Industry and FDA Staff - Class II Special Controls Guidance Document: Resorbable Calcium Salt Bone Void Filler Device (issued June 2003) and Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile (issued January 2016). The non-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalence included physical properties, sterilization, material-mediated pyrogenicity, product shelf life, and biocompatibility.
Animal testing was performed in a rabbit posterolateral fusion model and in a rabbit criticalsized defect model to demonstrate substantial equivalence to a legally marketed predicate devices. Further, a clinical study demonstrating the safety and effectiveness of the subject device when used in the posterolateral spine was conducted to further substantiate substantial equivalence. In this submission, non-clinical bench testing was performed to demonstrate that the subject device, hydrated with blood or autologous bone, remains in-situ in the graft window of worst-case FDA cleared interbody fusion devices. Additional rationales were provided to justify the expanded indications based upon the non-clinical and clinical data results.
Substantial Equivalence:
The subject device was demonstrated to be substantially equivalent to the NuVasive AttraX Putty (K203714) primary predicate device with respect to indications, design principles, and performance.

Image /page/6/Picture/0 description: The image shows the logo for Kuros Biosciences. The logo consists of a stylized, abstract symbol on the left and the company name "Kuros Biosciences" on the right. The symbol is composed of three interconnected shapes in green, blue, and yellow, forming a circular or triangular pattern. The text is in a simple, sans-serif font.
The subject device and primary predicate device both incorporate calcium phosphate materials (within a resorbable polymeric binder or scaffold) and are provided in multiple size options. The subject and primary predicate devices are provided sterile using similar radiation sterilization methods and are intended for single-patient and single-use.
The subject device is identical to the reference device (MagnetOs Granules, K213111). The performance of the reference device has previously been assessed at the time of prior clearance.
Non-clinical testing data, animal testing data, and spine fusion clinical testing data, supplemented with a clinical rationale, are referenced to demonstrate the performance of the subject device is substantially equivalent to that of the predicate device.
Any differences in the technological characteristics between the subject and predicate devices do not raise new issues or concerns of safety or efficacy.
Conclusion:
The subject device and the predicate devices have intended use, have similar technological characteristics, and are made of similar materials. The subject and predicate devices are packaged in similar materials and are sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above. MagnetOs Granules is as safe, as effective, and performs as well as, or better, than the predicate devices.
