The summary describes hip implants and wear testing, with no mention of AI or ML.
No
The device, described as "Duration™ Stabilized UHMWPE - Hip Components," is an implant used in total hip arthroplasty to replace damaged hip components, rather than for treating a condition directly.
No
The device is described as an insert for hip arthroplasty, which is a treatment, not a diagnostic tool.
No
The device description and performance studies clearly indicate this is a physical medical device (hip components) undergoing wear testing, not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes the device as components for total hip arthroplasty (hip replacement surgery). This is a surgical procedure performed on a patient's body.
- Device Description: The device is described as "Hip Components," further indicating its use as an implantable medical device.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment. The testing described is mechanical wear testing, not diagnostic testing of biological samples.
IVD devices are used outside the body to analyze biological samples. This device is designed to be implanted inside the body.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Howmedica's Duration™ Stabilized UHMWPE, System 120, size P4, neutral acetabular inserts, with an inner diameter of 32mm, a bearing thickness of 6.1 mm and aged for 6 months in an oxygen environment, showed a 36% reduction in volumetric wear versus the same cup conventionally gamma sterilized and aged for 6 months in an oxygen environment. Testing was performed in a multlaxial hip joint simulator for over 10 million cycles, using a 32mm CoCr Head articulating counterface and bovine calf serum as a lubricant. The results of in vitro tests have not been shown to correlate with clinical wear mechanisms.
Howmedica's Duration™ Stabilized UHMWPE, a hemispherical cup of generic design for hip simulator testing, with an inner diameter of 32 mm, and a bearing thickness of 8.4 mm, showed a 40% reduction in volumetric wear versus the same cup conventionally gamma sterilized. Testing was performed in a multiaxial hip joint wear simulator for over 5 million cycles, using a 32 mm diameter CoCr Head articulating counterface and "low calcium" containing bovine calf serum as a lubricant. The results of in vitro tests have not been shown to correlate with clinical wear mechanisms.
Howmedica's Duration™ Stabilized UHMWPE, System 12® Neutral Acetabular Insert, size P4, with an inner diameter of 32mm, and a bearing thickness of 6.1 mm, showed a 40% reduction in volumetric wear versus the same cup conventionally gamma sterilized. Testing was performed in a hip joint wear simulator for over 5 million cycles, 32 mm CoCr Head articulating counterface and "high calcium" containing a using a bovine calf serum as a lubricant. The results of these in vitro tests have not been shown to correlate with clinical wear mechanisms or in vitro third body wear mechanisms involving fragments of bone, bone cement, UHMWPE , metal, ceramic, etc.
In an independent laboratory test on Howmedica's Duration™ Stabilized UHMWPE, a hemispherical cup of generic design for hip simulator testing, with an inner diameter of 32 mm, a bearing thickness of 8.4 mm, and having undergone 11 days of healing in air to simulate 5 years "aging", showed a 27% reduction in volumetric wear versus the same cup conventionally gamma sterilized, having undergone 11 days of heating in air to simulate 5 years "aging". Testing was performed in a multiaxial hip joint wear simulator over 10 million cycles, using a 32 mm CoCr Head articulating counterface and bovine calf serum as a lubricant. The results of in vitro tests have not been shown to correlate with clinical wear mechanisms.

§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular 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 Mr. Dichiara:
We have reviewed your Section 510(k) notification of intent to market the devices referenced above and we have determined these devices are substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), they may be subject to such additional controls. Existing major regulations affecting your devices can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice for Medical Devices: General (GMP) requlation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your devices in the Federal Register. Please note: this response to your premarket notification submission does not affect any

obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your devices as described in your 510 (k) premarket notification. The FDA finding of substantial equivalence of your devices to legally marketed predicate devices results in a classification for your devices and thus, permits your devices to proceed to the market.
ff you desire specific advice for your devices on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4659. Additionally, for questions on the promotion and advertising of your devices, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
