No
The description focuses on the mechanical and electrical components of the device for limb lengthening and does not mention any AI or ML capabilities.
Yes
The device is indicated for limb lengthening of the femur, which is a medical treatment designed to improve a patient's physiological function.
No
This device is a fully implantable intramedullary lengthening nail designed for limb lengthening of the femur, which is a therapeutic function rather than a diagnostic one.
No
The device description clearly states it is a fully implantable intramedullary lengthening nail and accessories, which are physical hardware components. While it includes a control set, the core device is a physical implant.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "limb lengthening of the femur." This is a surgical procedure performed on the patient's body.
- Device Description: The device is described as an "implantable intramedullary lengthening nail and accessories." It is surgically implanted into the bone.
- Mechanism of Action: The device works by mechanically distracting (lengthening) the bone using a motor and external control system.
- No mention of in vitro testing: There is no indication that this device is used to examine specimens derived from the human body (like blood, urine, tissue, etc.) outside of the body to provide information for diagnosis, monitoring, or treatment.
IVD devices are used to perform tests on samples taken from the body, not to directly treat or modify the body itself through implantation and mechanical action.

Device Description
The FITBONE® Trochanteric is a fully implantable intramedullary lengthening nail and accessories. The subject FITBONE® Trochanteric consists of the implantable intramedullary lengthening nail and accessories (Locking screws, Trial nails, K-wire and Convenience kits). The Subject device is implanted into the medullary canal of the femur and connected to the primary predicate intracutaneous Receiver (K163368) by a bipolar feed line. The external FITBONE Control Set is the same as previously cleared for the primary predicate Fitbone TAA device (K203399) and consists of a control electronics station and transmitter. There are no changes to the previously cleared Control Sets and Receiver as a result of this submission. The power required for the distraction process is controlled by hermetically enclosed motor which draws the telescope apart. The electro-magnetic field sent from the Transmitter to the Receiver is converted in the Receiver into DC-Voltage to supply the motor of the subject Fitbone Trochanteric Nails with voltage, when actioned. The subject Fitbone Trochanteric Nails are available in two different diameter models (D09mm, D11mm), different lengths and lengthening capabilities. The subject nail is anchored to the bone by subject locking screws. The locking screws are available in two variants (standard locking screws and revision locking screws), in two diameters, D4.5mm and D4mm, and in multiple lengths. The energy needed for the distraction process is transmitted from the outside by placing the external transmitter over the implanted receiver, which is placed in the subcutaneous tissue during surgery. There is no transcutaneous contact between the implanted intramedullary nail and the outer surface of the patient's body. The subject trial nails accessories are available for each variant of the Fitbone Trochanteric nails and are used to simulate the shape of the implant. The subject Fitbone Trochanteric nail and K-wire are provided in sterile conditions only. The trial nails are provided in non-sterile version only. The bone screws are available in both sterile and non-sterile versions. The subject Fitbone Trochanteric Nails and their accessories are made from, as follows: Nail: implant grade stainless steel 1.4441, according to ASTM F138-13 "Standard Specification for Wrought 18Chromium-14Nickel-2.5Molybdenum Stainless Steel Bar and Wire for Surgical Implants (UNS S31673)", and Silicone Nusilmed (NuSil MED-4870, NuSil MED-1511, Nusil MED 4750, NUSIL MED1-161, NUSIL MED2-4502). Trial nail: implant grade stainless steel 1.4441, according to ASTM F138-13 "Standard Specification for Wrought 18Chromium-14Nickel-2.5Molybdenum Stainless Steel Bar and Wire for Surgical Implants (UNS S31673)" and ASTM F899-20 Standard Specification for Wrought Stainless Steels for Surgical Instruments. Locking screws: implant grade stainless steel 1.4441, according to ASTM F138-13 "Standard Specification for Wrought 18Chromium-14Nickel-2.5Molybdenum Stainless Steel Bar and Wire for Surgical Implants (UNS S31673)" K-wire: implant grade stainless steel 1.4441, according to ASTM F138-13 "Standard Specification for Wrought 18Chromium-14Nickel-2.5Molybdenum Stainless Steel Bar and Wire for Surgical Implants (UNS S31673)"

Dear Elvira Taccarelli:
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.

following mechanical testing was performed:
Implantable nails and screws:
Static and fatigue 4-point bending test for subject Fitbone Trochanteric nails performed according to ASTM F1264-16 - "Standard Specification and Test Methods for Intramedullary Fixation Devices", 4-point bending test for subject locking screws per ASTM F1264-16 - "Standard Specification and Test Methods for Intramedullary Fixation Devices", Axial Load and vibration tests of subject Fitbone Trochanteric nails per custom test protocol, Testing of subject Fitbone Trochanteric nails per ISO 14708-1:2014 - "Implants for surgery - Active implantable medical devices - Part 1: General requirements for safety, marking and for information to be provided by the manufacturer", Torsional strength, insertion/removal torque, self-tapping properties, and pull out test performed according to ASTM F543-17. | |
| Conclusion | | Based upon equivalences in: intended use, patient population, site of application,
conditions of use, operating principles, and the non-clinical performance data, the
subject FITBONE® Trochanteric nail have been shown to be safe and effective and
to perform equivalently as compared to the legally marketed predicate device
(K203399). | |
