The device description and intended use are purely mechanical, and there is no mention of AI, ML, image processing, or data analysis related to the device's function.
Yes.
The device is a component of a total hip prosthesis, which is used for primary or revision total hip arthroplasties to address conditions like high risk of hip dislocation, instability, or bone loss. These are therapeutic interventions designed to treat a medical condition and restore function.
No
Explanation: The device is a constrained acetabular liner for total hip arthroplasties, designed to prevent dislocation. Its function is to replace or assist a body part, not to diagnose a disease or condition.
No
The device description clearly states it is a physical implantable device made of polyethylene and metal, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's for "primary or revision total hip arthroplasties," which is a surgical procedure involving the hip joint. IVDs are used to examine specimens (like blood, urine, or tissue) outside the body to provide information about a patient's health.
- Device Description: The description details a physical implantable device (a polyethylene/metal acetabular liner) that forms part of a hip prosthesis. This is not a diagnostic tool used for testing samples.
- Anatomical Site: The anatomical site is the "Hip joint," indicating it's used within the body.
- Lack of IVD characteristics: There is no mention of analyzing samples, performing tests on biological material, or providing diagnostic information based on laboratory results.
Therefore, the Trilogy® Longevity® Constrained Liner is a medical device used for surgical implantation, not an in vitro diagnostic device.

Intended Use / Indications for Use
The Trilogy Longevity Constrained Liner is indicated for primary or revision total hip arthroplasties where there is a high risk of hip dislocation due to a history of instability, bone loss, joint, muscle or tissue laxity, or disease condition. This device is intended for patients for whom all other options to constrained acetabular components have been considered.

Device Description
The Trilogy Longevity Constrained Liner is a polyethylene/metal acetabular liner, which, when used with a Trilogy or Trabecular Metal Modular Acetabular Shell, forms the acetabular component of a total hip prosthesis. The device consists of a Longevity Highly Crosslinked Polyethylene Liner and a Tivanium alloy constraining ring.
The liner allows for mechanical capture of the metal femoral head and greater flexion/extension range of motion than hooded constrained liner designs.
The Trilogy Longevity Constrained Liner is a design modification of the Epsilon Durasul Constrained Acetabular Liner. The material has been changed to Longevity Highly Crosslinked Polyethylene, the finger and ring designs have been modified to ease assembly and the backside has been modified for use with Trilogy and Trabecular Metal Modular Acetabular Shells.

§ 888.3310 Hip joint metal/polymer constrained cemented or uncemented prosthesis.
(a)
Identification. A hip joint metal/polymer constrained cemented or uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device prevents dislocation in more than one anatomic plane and has components that are linked together. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular component made of ultra-high-molecular-weight polyethylene with or without a metal shell, made of alloys, such as cobalt-chromium-molybdenum and titanium alloys. This generic type of device is intended for use with or without bone cement (§ 888.3027).(b)
Classification. Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Hip Joint Metal/Polymer Constrained Cemented or Uncemented Prosthesis.”

Dear Mr. McKelvey:
We have reviewed your Section 510(k) premarket notification of intent to market the devices referenced above and have determined the devices are 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 devices, 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.
If your devices are classified (see above) into either class II (Special Controls) or class III (PMA), they may be subject to such additional controls. Existing major regulations affecting your devices can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your devices 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 devices comply 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); 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.
This letter will allow you to begin marketing your devices as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your devices to a legally marketed predicate device results in a classification for your devices and thus, permits your devices to proceed to the market.
If you desire specific advice for your devices on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at toll-free number (800) 638-2041 or (240) 276-3150 or the Internet address http://www.fda.gov/cdrl/industry/support/index.html
