The summary describes a mechanical implant (a constrained hip liner) and its performance testing, with no mention of software, algorithms, or AI/ML capabilities.
No
The device is a medical device intended to mechanically stabilize a total hip prosthesis, not to provide therapy.
No
The device description indicates that it is a component of a total hip prosthesis designed to capture the femoral head and reduce dislocation, not to diagnose a condition.
No
The device description clearly states it is a physical component (a modular acetabular shell liner) made of polyethylene and a Tivanium® ring, intended for surgical implantation. It is a hardware device, 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 describes a device implanted in the body to treat a physical condition (hip dislocation). IVDs are used to examine specimens (like blood, urine, or tissue) outside the body to provide information for diagnosis, monitoring, or screening.
- Device Description: The description details a physical implantable component for a total hip prosthesis. This is consistent with a medical device used in surgery, not a diagnostic test.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples.
- Providing diagnostic information based on laboratory tests.
- Reagents, calibrators, or controls.
- Use in a laboratory setting.
The device described is a medical device used in surgical procedures.

Intended Use / Indications for Use
The Longevity IT Constrained Liner is indicated as a component of a total hip prosthesis in 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 Longevity Integrated Taper (IT) Constrained Liner is a modular acetabular shell liner intended to capture the femoral head of a total hip prosthesis to reduce the incidence of joint dislocation. The liners feature integral polyethylene "fingers" reinforced with a modular Tivanium ring to capture the mating femoral head. The Longevity IT Constrained Liners are intended to mate with Continuum and Trilogy IT acetabular shells.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical testing was conducted on the proposed device per FDA's Guidance Document, "Class II Special Controls Guidance Document: Hip Joint Metal/Polymer Constrained Cemented or Uncemented Prosthesis". This testing demonstrated that the Longevity IT Constrained Liners performed as intended and met all acceptance criteria.
The Longevity IT Constrained Liner design and geometry were evaluated to demonstrate that the proposed device met performance requirements and is as safe and effective as its predicate. This information and testing data formed the basis for a determination of substantial equivalence.
Specific Non-clinical Testing Completed:
- Head Pull-Out Fatigue Test
- Rim Impingement Fatigue Test
- Static Head Pull-Out Test
- Static Rim Impingement Lever-Out Test t
- Liner Locking Mechanism Strength Analysis
- Anatomic Fatigue Analysis
- Constrained Liner Wear Performance
- Liner Durability and Backside Wear
- Temperature Effects on Liner Assembly

§ 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.”
