No
The summary describes image processing and software for preoperative planning and guide design, but there is no mention of AI or ML algorithms being used for these processes. The focus is on patient-specific instrumentation and planning based on imaging scans.
No.
The device is described as "patient specific surgical instrumentation to assist in the positioning of total ankle replacement components intraoperatively, in guiding the marking of bone before cutting, and in the pre-surgical planning." It facilitates surgery but does not directly treat a disease or condition itself.
No
The device is intended for surgical planning and guidance, assisting in the positioning of total ankle replacement components and guiding bone marking, rather than diagnosing a disease or condition. It processes existing imaging data to help with surgery, not to make a diagnosis.
No
The device description explicitly states that the system is composed of three components, one of which is "Prophecy® patient-specific guides," which are described as "patient-specific devices." This indicates a hardware component is part of the system, not just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The Prophecy® Preoperative Navigation Alignment System is a surgical planning and guidance system. It uses patient imaging (CT scans) to create patient-specific guides and reports that assist surgeons in planning and performing total ankle replacement surgery. It does not analyze biological samples from the patient's body.
- Intended Use: The intended use is to assist in surgical procedures (positioning components, guiding marking, pre-surgical planning), not to diagnose or monitor a medical condition through the analysis of biological samples.
Therefore, the Prophecy® Preoperative Navigation Alignment System falls under the category of surgical planning and guidance devices, not in vitro diagnostics.
N/A
Intended Use / Indications for Use
The 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, in guiding the marking of bone before cutting, and in the pre-surgical planning of the ankle and surrounding anatomy to support the total ankle implant. The Prophecy® Preoperative Navigation Alignment Guides and Reports are intended for use with the 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. The Prophecy® Preoperative Navigation Alignment Guides are intended for single use only.

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)

The subject device and predicate device have the same key technological characteristics as follows:
- . The system processes original patient medical images (i.e., CT scans) and produces patient-specific digital outputs to create a preoperative report and patient specific alignment guides.
- . Validated commercially off-the-shelf software applications are used for image segmentation, transfer of patient imaging from a DICOM format to an .STL format, and guide design.
- . Requires trained employees/engineers to manipulate data, using software applications.
- Surgeon works with employees/engineers by providing inputs for implant alignment, implant size and implant type modifications.
- . Patient-specific alignment guides and bone models are 3D printed via additive manufacturing as the physical output devices.
- . Preoperative case reports are produced as an output for planning total ankle replacement surgeries.
The subject device. Prophecy® Preoperative Navigation Alignment System, is substantially equivalent in materials and performance characteristics to the predicate device.
- . The modifications do not affect the device's intended use.
- . No changes to the patient-specific alignment guides, preoperative report, or other software components are proposed by this submission.
This submission proposes the following modifications to the subject device:
- Addition of the Prophecy® 3D Planner software, which gives surgeons the ability to ● modify the implant type, implant size and implant orientation via a user interface.
- Changes to the Guide Design Process due to addition of the Prophecy® 3D Planner ● software.
5
The technological differences between the subject and predicate devices are supported with verification and validation evaluations. The differences in design specifications do not raise any new questions of safety and effectiveness over the predicate, which is demonstrated in the performance testing and process validation.
(b)(1). Substantial Equivalence - Non-Clinical Evidence
Performance data and information demonstrating the safety and effectiveness of the Prophecy® Navigation Alignment System with the 3D Planner software is supported by testing that was conducted in-house. This submission includes the following non-clinical testing:
- Software verification testing to ensure all design outputs meet all specified requirements. .
- Software validation to ensure software specifications conform to user needs and intended ● uses.
- . Usability test to ensure the software is safe and effective for the intended users, uses and use environments.
The software verification and validation were performed in accordance with FDA Guidance Document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices '' (issued May 11, 2005). The usability was performed in accordance with FDA guidance document "Applying Human Factors and Usability Engineering to Medical Devices" (issued February 18, 2016).
All test results met the acceptance criteria, demonstrating the subject device performs as intended and is substantially equivalent to the predicate device.
(b)(2). Substantial Equivalence- Clinical Evidence
Clinical testing was not necessary for the determination of substantial equivalence.
(b)(3). Substantial Equivalence- Conclusions
The subject device and predicate device share identical intended use, general design features and basic fundamental scientific technology. The differences between the subject device and predicate device do not raise any new questions of safety or effectiveness. From the evidence submitted in this Traditional 510(k), the subject device can be expected to perform at least as well as the predicate device and are substantially equivalent.
