The device description and performance studies focus on the mechanical properties and design of a physical implant, with no mention of software, algorithms, or data processing related to AI/ML.
No.
The device replaces a body part (acetabulum) to restore function rather than treating a disease or condition.
No
This device is an implantable medical device used in hip arthroplasty, not a device used to diagnose a condition.
No
The device description explicitly states it consists of a titanium shell and UHMWPE insert, which are physical hardware components.
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 testing is done outside of the body (in vitro).
- Device Description: The BOFOR Revision Cup is a physical implant designed to be surgically placed inside the human body to replace the acetabulum in a hip joint.
- Intended Use: Its intended use is a surgical procedure (revision hip arthroplasty), not a diagnostic test performed on a specimen.
The information provided clearly describes a surgical implant, not a device used for in vitro testing.

Device Description
The BOFOR Revision Cup consists of a titanium shell (Ti 6Al 4V) and an UHMWPE insert with a pure titanium cover shell. The BOFOR cup is asymmetrical and elongated, giving it a slightly "bean-shaped" design. This bean shape gives better three-point anchorage and provides better protection for the posterior column of the acetabulum. Other features of the BOFOR cup include a decentralized acetabulum inlay, cancellous bone screw anchorage, external fixation ribs, and a cranial keel, which acts as an adjuvant support column. The BOFOR cup comes in six sizes with compatible PE inserts in three sizes.

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.
(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)
Classification. Class II.

Dear Mr. Loch:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is 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 device, subject to the general control provisions of the Act. The general control provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) 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 device 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 device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
