"FITBONE Transport and Lengthening system" is indicated for limb lengthening, open and closed fracture fixation, pseudoarthrosis, malunions, non-unions, or bone transport of the long bones. The "FITBONE Transport and Lengthening system" is indicated for adult only.
The subject “FITBONE® Transport and Lengthening System” consists of the implantable intramedullary transport or lengthening nail and its trial nail accessories. The Subject device is implanted into the medullary canal of the femur or tibia and connected to the additional predicate intracutaneous Receiver by a bipolar feed line. The external FITBONE Control Set is identical to that previously cleared for the additional predicate Fitbone TAA device (K203399) and consists of a control electronics station and transmitter. There are no changes to this 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 FITBONE Transport and Lengthening Nail with voltage, when actioned. The subject nail is anchored to the bone by locking screws through medial-lateral and AP holes in the nail depending on the configuration holes in the nail. 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 size model of the FITBONE Transport (TN) and FITBONE Transport or Lengthening (TLN) nails and are used to simulate the shape of the implant. The subject nails and trial nails are provided in sterile conditions only and 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). • 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 For the implantation and removal of the subject device the same instruments of the additional predicate Fitbone TAA (K203399) may be used.
The provided text is a 510(k) summary for a medical device (FITBONE® Transport and Lengthening System). It details the device's indications for use, technological characteristics, and a comparison to predicate devices, but it does not contain information about acceptance criteria or a study proving the device meets those criteria in the context of an AI/ML-based medical device.
The document describes mechanical testing (bench testing) to demonstrate the equivalence of the subject device to its predicates for physical attributes like bending, fatigue, and torsional strength, and current consumption of the motor. This is typical for implantable mechanical devices.
Therefore, I cannot provide the requested information regarding acceptance criteria and studies for an AI/ML device, including details about sample sizes, data provenance, expert qualifications, ground truth establishment, or MRMC studies, as these concepts are not applicable to the content provided in the input text.
The document discusses performance in terms of mechanical and functional equivalence of a physical medical device, not the performance of an AI/ML algorithm.
