No
The 510(k) summary describes a mechanical hip implant system and the performance studies are focused on biocompatibility and mechanical testing. There is no mention of AI or ML in the device description, intended use, or performance studies.

Yes

This device is a hip implant, which is a prosthetic device designed to replace damaged or diseased parts of the hip joint. Its intended use includes treating conditions like advanced hip degeneration, fractures, and failures of previous hip surgeries, all of which are medical conditions that require intervention to restore function and alleviate symptoms. Therefore, by directly addressing these medical conditions and aiming to improve a patient's health and quality of life, it functions as a therapeutic device.

No
The device is an acetabular hip cup prosthesis, specifically an implant for total hip replacement, used to treat conditions like advanced hip degeneration, femoral head fractures, or failed previous hip surgeries. It is a therapeutic device, not a diagnostic one.

No

The device description clearly states it is a physical implantable device made of titanium alloy and stainless steel, intended for surgical implantation in the hip joint. It is 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 for surgical implantation to replace or repair a damaged hip joint. This is a therapeutic and structural function within the body.
  • Device Description: The description details the materials and design of an artificial hip joint component (acetabular shell and dual mobility system). These are physical implants.
  • Performance Studies: The performance studies focus on biocompatibility and mechanical testing of the implant's structural integrity and interaction with bone and other components. This is typical for implantable medical devices, not IVDs.
  • 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) to provide information for diagnosis, monitoring, or screening.

In summary, the device is a surgical implant designed to replace a damaged hip joint, which falls under the category of a medical device, but not an In Vitro Diagnostic device.

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.

(a)
Identification. A hip joint metal/polymer/metal semi-constrained porous-coated uncemented 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.(b)
Classification. Class II.

Dear Bryan Cowell:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

V. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

There are no technological differences between the subject and predicate REDAPT Porous Acetabular Shells K150790 (S.E. 11/16/2015).

There are no technological differences between the POLARCUP Dual Mobility System components and the previously cleared POLARCUP Dual Mobility System components K110135 (S.E. 10/14/2011).

To allow for a dual mobility option for the existing REDAPT Porous Acetabular Shells, this submission allows for the existing POLARCUP Dual Mobility System to be implanted in the REDAPT Porous Acetabular Shells with bone cement.

As the devices are identical to the existing 510(k) cleared devices, the technological characteristics assessed consisted of the compatibility of the two systems.

Bacterial endotoxin testing was completed and met the acceptable endotoxin limits as stated in the FDA Guidance , "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile," "Pyrogen and Endotoxins Testing: Questions and Answers," and ANSI/AAMI ST72.

Therefore, the technological characteristics of the subject device are the similar to the technological characteristics of the predicate devices REDAPT Porous Acetabular Shells (S.E. (K150790 (S.E. 11/16/2015) and POLARCUP Dual Mobility System (S.E. K150522 (S.E. 05/01/2015)).
