Wright's PROPHECY® Preoperative Navigation Alignment System is intended to be used as patient specific surgical instrumentation to assist in the positioning of total ankle replacement components intraoperatively and in guiding the marking of bone before cutting. The PROPHECY® Preoperative Navigation Alignment Guides are intended for use with Wright's INBONE® and INFINITY® Total Ankle Systems and their cleared indications for use, provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans. The PROPHECY® Preoperative Navigation Alignment Guides are intended for single use only. The PROPHECY® Preoperative Reports are intended for use with Wright's INBONE®, INFINITY® and INVISION® Total Ankle Systems and their cleared indications for use, provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans.

Device Description

PROPHECY® Preoperative Navigation Alignment System provides the surgeon a template of the patient's distal tibial and proximal talar anatomy. The PROPHECY® alignment report serves as a template for traditional alignmentation used with Wright's INBONE®, INFINITY , and INVISION® Total Ankle Systems.

AI/ML Overview

The provided document does not contain information regarding a specific study with acceptance criteria and a detailed analysis of device performance against those criteria. The document is a 510(k) summary for the PROPHECY® INVISION® Preoperative Navigation Alignment System, which focuses on demonstrating substantial equivalence to predicate devices rather than presenting a performance study with detailed acceptance criteria and reported device performance.

Therefore, I cannot provide the requested information. The sections concerning sample size, data provenance, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, and training set details are not present in this document.

The "Design repeatability across design engineers" and "Software validation" mentioned in section 7 ("Substantial Equivalence- Non-Clinical Evidence") are very high-level statements and do not provide the detailed performance metrics, acceptance criteria, or study methodologies that would allow for a comprehensive answer to your request.

Dear Tara Conrad:

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 devicerelated adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

marking of bone before cutting. The PROPHECY® Preoperative Navigation Alignment Guides are intended for use with Wright's INBONE® and INFINITY® Total Ankle Systems and their cleared indications for use, provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans. The PROPHECY® Preoperative Navigation Alignment Guides are intended for single use only. The PROPHECY® Preoperative Reports are intended for use with Wright's INBONE®, INFINITY® and INVISION® Total Ankle Systems and their cleared indications for use, provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans.

6. Technological Characteristics Comparison

The PROPHECY® Preoperative Navigation Alignment system has identical indications, is made from identical materials and software when compared to the legally marketed predicate devices.

7. Substantial Equivalence- Non-Clinical Evidence

The main difference between the subject and predicate PROPHECY® systems is the addition of use with the INVISION® Total Ankle System. The following evaluations were conducted to support the safety and efficacy of the PROPHECY® INVISION® Alignment Report:

Design repeatability across design engineers -
-Software validation

These evaluations concluded the subject alignment guide is substantially equivalent to the predicates.

8. Substantial Equivalence- Clinical Evidence

N/A

9. Substantial Equivalence- Conclusions

The design characteristics of the subject devices do not raise any new types of questions of safety or effectiveness. From the evidence submitted in this 510(k), the subject devices can be expected to perform at least as well as the predicate systems and are substantially equivalent.

Regulation Number and Section

§ 888.3110 Ankle joint metal/polymer semi-constrained cemented prosthesis.

(a)
Identification. An ankle joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace an ankle joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces and has no linkage across-the-joint. This generic type of device includes prostheses that have a talar resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a tibial resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
