The device description and performance studies focus on the material properties and biological function of a bone void filler, with no mention of AI or ML technologies.
Yes
MagnetOs Putty is an implant intended to fill bony voids or gaps of the skeletal system to aid in the healing process by providing a scaffold for new bone growth, which is a therapeutic function.
No
This device is described as an implant intended to fill bony voids or gaps and is replaced by bone during the healing process. Its function is therapeutic/restorative, not diagnostic.
No
The device description clearly states that MagnetOs Putty is a synthetic, resorbable, osteoconductive bone void filler consisting of physical components (granules and polymeric binder). It is a physical implant, not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that MagnetOs Putty is an "implant intended to fill bony voids or gaps of the skeletal system". This describes a device that is surgically placed within the body to treat a physical condition.
- Device Description: The description details the composition of the implant (TCP, HA, polymeric binder) and its function in bone regeneration. This aligns with the description of a medical device used for surgical intervention.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue samples) to provide information for diagnosis, monitoring, or screening.
IVD devices are used in vitro (outside the body) to analyze biological samples. This device is used in vivo (inside the body) as a surgical implant.
N/A
Intended Use / Indications for Use
MagnetOs Putty is an implant intended to fill bony voids or gaps of the skeletal system i.e., the extremities, pelvis and posterolateral spine. MagnetOs Putty may be used standalone or mixed with autograft. 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. MagnetOs Putty resorbs and is replaced with bone during the healing process.

Device Description
MagnetOs Putty is a synthetic, resorbable, osteoconductive bone void filler for the repair of bony defects. MagnetOs Putty 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. The granules are covered with submicron-sized features and are premixed with a synthetic polymeric binder. The biocompatible polymeric binder is composed of Poly L (Lactic Acid) (PLA) and Poly(Ethylene Glycol) (PEG) in a triblock polymer PLA-PEG-PLA; which consists of 10-20% PLA and 80-90% PEG.
The fast-resorbing polymeric binder in the subject device is improve handling properties, as well as reduce the risk of granules migration. While the polymeric binder is rapidly resorbed after implantation, the granules in both devices guide the three-dimensional regeneration of bone in the defect site into which it is implanted.
When placed next to viable host bone, new bone will be deposited on the surface of the implant. The implant resorbs and is replaced by bone during the natural process of bone remodeling. MagnetOs Putty is a ready-for-use product. Pressure applied by manipulation allows the shaping of the devices to conform to the contours of bony defects. MagnetOs Putty is gamma-sterilized, comes in several sizes in block form and is sterile packaged for single use only.
This 510(k) expands the device's indications for use in K181958 as an autograft extender only to also allow use of the device alone in posterolateral spine.

Predicate Devices:
Kuros Biosciences submits the following information in this Premarket Notification to demonstrate that, for the purposes of FDA's regulation of medical devices, MagnetOs Putty is substantially equivalent in indications, design principles, and performance to the following predicate devices:
| Primary Predicate: | MagnetOs Granules (K213111) |
|---|---|
| Additional Predicates: | MagnetOs Putty (K181958) |
| NuVasive AttraX Putty (K191974) |
Performance Testing Summary:
In support of the prior clearance of MagnetOs Putty (K181958), non-clinical testing data were submitted according to the "Guidance for Industry and FDA Staff - Class II Special Controls Guidance Document: Resorbable Calcium Salt Bone Void Filler Device (issued June 2003)". Bench testing data including analytical characterization, chemical composition, physical properties and animal functional study were conducted for the subject MagnetOs Putty and the predicate devices. The results of the studies demonstrate substantial equivalence to the predicate devices.
Similar to the predicate MagnetOs Putty (K181958), the subject device is categorized as direct-patient contact with boneltissue for permanent duration (>30 days). Biocompatibility was performed in accordance with "ISO 10993-1, Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process".
MagnetOs Putty met the acceptance criteria for the Limulus amebocyte lysate (LAL) test, gel clot
6
method (Bacterial endotoxins test (BET)) per Ph.Eur. 2.6.14, Bacterial Endotoxins and USP , Bacterial Endotoxins. MagnetOs Putty passed the Materials-Mediated Pyrogenicity Rabbit study per USP 39-NF34 and is marketed as "Non-Pyrogenic". A sterilization was performed and complies with ISO 11137, "Sterilization of Sterilization of Health Care Products – Radiation", to ensure a sterility assurance level (SAL) of 10 °. Product and sterile-barrier shelf-life studies were conducted per ISO 11607, "Packaging for terminally sterilized medical devices".
The performance of the MaqnetOs Putty for standalone use was the same compared to the primary predicate MagnetOs Granules in posterolateral spinal fusion (PLF) animal model, was confirmed with a small clinical data set.
Substantial Equivalence:
The subject device, Primary Predicate device MagnetOs Granules (K213111), and Additional Predicate NuVasive AttraX Putty (K191974) have the same intended use, indications for use, product classification, and product code (MQV).
MagnetOs Putty's granular component is identical to Primary Predicate MagnetOs Granules (K213111), i.e. porous biphasic calcium phosphate granules with submicron-sized features. The subject device MagnetOs Putty is identical to the Additional Predicate MagnetOs Putty (K181958) in technological characteristics including materials, manufacturing process, with similar indications for use and therefore the biological evaluation conducted for the predicate MagnetOs Putty (K181958) is applicable to the subject device.
In vivo testing supported the substantial equivalence of MagnetOs Putty with Primary Predicate device MagnetOs Granules (K213111) for the expanded standalone use in posterolateral spine.
Conclusion:
The subject device and predicate devices have the same intended use, have similar technological characteristics, manufacturing process, and are made of similar materials. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above. MagnetOs Putty is as safe, as effective, and performs as well as the predicate devices for the indications for use.
