The LeForte Neuro System Bone Plate & Screw is made of pure Titanium (ASTM F67) and Titanium Alloy (ASTM F136). It is intended for use in selective trauma of the cranial skeleton, cranial surgery and reconstructive procedures.

AI/ML Overview

The provided document is a 510(k) summary for a medical device (LeForte Neuro System Bone Plate & Screw) seeking substantial equivalence to existing predicate devices. It does not describe a study to prove acceptance criteria in the way one would for a novel device demonstrating safety and effectiveness.

Instead, the submission focuses on demonstrating that the new device has the same characteristics, material, design, and intended use as already cleared predicate devices. Therefore, many of the requested categories (like sample size, ground truth, expert opinions, MRMC studies, standalone performance) are not applicable or not detailed in this type of submission.

Here's a breakdown of the available information based on your request:

1. Table of Acceptance Criteria and Reported Device Performance:

This document does not present a table of quantitative acceptance criteria for device performance in terms of clinical outcomes or specific measurements. Instead, the "acceptance criteria" are implicitly met by demonstrating substantial equivalence to predicate devices. The "reported device performance" is essentially that its characteristics (material, dimensions, shape, sterilization, use, packaging) are either identical or acceptably similar to the predicate devices.

Parameter	Acceptance Criteria (Implied - Substantial Equivalence to Predicates)	Reported Device Performance (LeForte Neuro System Bone Plate & Screw)
K#	Substantially equivalent to K091679, K103778, K091686	Modified (new K# K112812)
Indications for Use	Must be identical to or a subset of predicate indications.	"This device is intended for use in selective trauma of the cranial skeleton, cranial surgery and reconstructive procedures." (Identical to predicate)
Shape	Must be acceptably similar, with potential additions.	The same models as predicate, "with the addition of Triangular shapes".
Dimensional	Acceptably similar to predicate dimensions.	Plate thickness 0.3~~0.6mm; Screw Outer diameter 1.4~~1.9mm; Screw Length 2.2~~5.0mm (Predicate screws 3.0~~5.0mm)
Material	Identical to predicate materials.	Plate - Titanium ASTM F67 Grade1, 2, 3; Screw - Titanium Alloy ASTM F136 (Identical to predicate)
Surface	Identical to predicate.	Plate: Anodizing; Screw: N/A (Predicate not specified in table, but assumed to be equivalent)
Sterilization	Identical to predicate.	Non sterile (Predicate not specified in table, but assumed to be equivalent)
Single Use	Identical to predicate.	Yes (Predicate not specified in table, but assumed to be equivalent)
Packaging	Identical to predicate.	Vial, PA+PE film sealing (Predicate not specified in table, but assumed to be equivalent)

2. Sample Size Used for the Test Set and Data Provenance:

Not Applicable. This submission is for substantial equivalence to existing devices, not a de novo clearance requiring clinical studies with test sets in the typical sense. There is no specific clinical "test set" described. The focus is on comparing the device's physical and functional characteristics to legally marketed predicates.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of those Experts:

Not Applicable. As there's no clinical test set in this context, there's no need for experts to establish ground truth on patient data. The "ground truth" here is the established safety and effectiveness of the predicate devices.

4. Adjudication Method for the Test Set:

Not Applicable. No clinical test set.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was Done:

No. MRMC studies are used for diagnostic devices to assess reader performance. This device is a surgical implant.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was Done:

Not Applicable. This device is a physical surgical implant, not an algorithm or AI.

7. The Type of Ground Truth Used:

The "ground truth" for this 510(k) submission is the established safety and effectiveness of the predicate devices (Jeil Medical Corporation LeForte Neuro System Bone Plate / K091679, K103778, and LeForte Neuro System Bone Screw / K091686) as determined by their prior FDA clearances. The applicant's goal is to demonstrate that their new device is fundamentally the same and therefore equally safe and effective.

8. The Sample Size for the Training Set:

Not Applicable. There is no "training set" in the context of this 510(k) submission for a physical medical device.

9. How the Ground Truth for the Training Set Was Established:

Not Applicable. As there's no training set, there's no associated ground truth establishment process.

LeForte Neuro System Bone Plate & Screw

1. Indications for Use:
  This device is intended for use in selective trauma of the cranial skeleton, cranial surgery and reconstructive procedures.
1. Contraindications:
- · Not for use in cases of active or suspected infection or in patients previously sensitized to Titanium.
- · Not for use in patients exhibiting disorders which would cause the patient to ignore the limitations of rigid fixation plate and screw implants.
1. Potential Adverse Affects:
- Poor bone formulation, Osteoporosis, Osteolysis, Osteomyelitis, inhibited revascularization, or infection can cause loosening, bending, cracking or fracture of the device or premature loss of fixation with the bone, leading to nonunion,
- Nonunion or delayed union which may lead to breakage of the implant
- Migration, bending, fracture or loosening of the implant
- Metal sensitivity, or allergic reaction to foreign body "
- . Decrease in bone density due to stress shielding
- . Pain, discomfort, or abnormal sensation due to the presence of the device
- . Increased fibrous tissue response around the fracture site and/or the implant
- . Necrosis of bone
- . Inadequate healing

Apart from these adverse effects there are always possible complications of any surgical procedure such as but not limited to, infection, nerve damage and pain which may not be related to the implant.

1. Predicate comparison:
  The LeForte Neuro System Bone Plate & Screw has the same device characteristics, material, design and intended use as the predicate devices identified.

Dear Mr. Sumner:

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 (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. 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical
