The summary describes a mechanical implant system and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is a total ankle revision system intended to treat damaged ankle joints by replacing movement and reducing pain, which aligns with the definition of a therapeutic device designed to treat or alleviate a medical condition.
No
The device is an orthopedic implant (ankle revision system) intended to replace joint function, not to diagnose a condition.
No
The device description explicitly lists physical components like tibial stems, talar domes, talar plates, and tibial trays, indicating it is a hardware-based implant system, not software only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- Device Description: The INVISION® Total Ankle Revision System is a prosthetic implant designed to be surgically implanted into the ankle joint. It is a physical device that replaces damaged anatomical structures.
- Intended Use: The intended use is to provide limited mobility, reduce pain, restore alignment, and replace movement in the ankle joint. This is achieved through the physical presence and function of the implant, not by analyzing biological specimens.
The information provided clearly describes a surgical implant, not a device used for testing biological samples.
N/A
Intended Use / Indications for Use
The INVISION® Total Ankle Revision System is indicated for patients with ankle joints damaged by severe rheumatoid, post-traumatic, or degenerative arthritis.
The INVISION® Total Ankle Revision System is additionally indicated for patients with a failed previous ankle surgery.
CAUTION: In the United States, the ankle prosthesis is intended for cement use only.

§ 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.

Dear Ms. 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.
