The Vector Hammertoe Correction System is indicated for the fixation of osteotomies and reconstruction of the lesser toes following correction procedures for hammertoe, claw toe, and mallet toe.

The Vector Hammertoe Correction System is comprised of a sterile PEEK (polyetheretherketone) HA (hydroxyapatite) fixation device. The implants are offered in Ø3.00mm, Ø3.50mm and Ø4.00mm and in 0° angle. The system has K-wires, drill, taps, implant inserters, and sizers manufactured from medical grade stainless steel.

The provided text does not contain information about the acceptance criteria and the study that proves the device meets the acceptance criteria, as it relates to performance metrics of a device, particularly an AI/imaging device. The document is an FDA 510(k) clearance letter for a medical device called the "Vector® Hammertoe Correction System," which is a bone fixation system, not an imaging or AI-driven diagnostic device.

Therefore, I cannot provide the requested information from the given text.

The document discusses:

• Device Name: Vector® Hammertoe Correction System
• Regulation Number: 21 CFR 888.3040 (Smooth Or Threaded Metallic Bone Fixation Fastener)
• Regulatory Class: Class II
• Indications for Use: Fixation of osteotomies and reconstruction of the lesser toes following correction procedures for hammertoe, claw toe, and mallet toe.
• Device Description: Sterile PEEK (polyetheretherketone) HA (hydroxyapatite) fixation device, K-wires, drill, taps, implant inserters, and sizers manufactured from medical grade stainless steel.
• Predicate Devices: K201850 (Nvision Biomedical's Vector Hammertoe Correction System), K183055 (Nvision Biomedical's Vector Hammertoe Correction System), and K193645 (Nvision Biomedical's nva, nvt).
• Non-Clinical Testing: Primarily engineering analysis comparing device characteristics (materials, intended use, cleaning, sterilization) to predicate devices. It states no FDA performance standards have been established for this device and that the results indicate substantial equivalence. The key modification mentioned is the addition of steam sterilization as an alternative method.

None of the information required for explaining acceptance criteria for an AI/imaging device, such as sample sizes for test and training sets, expert qualifications, adjudication methods, MRMC studies, standalone performance, or ground truth establishment, is present in this regulatory document.
