Intended Use
The M²a™/C²a™ Acetabular System is intended for cemented or non-cemented use in cases of: 1) Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis 2) Rheumatoid arthritis 3) Correction of functional deformity 4) Revision procedures where other treatment or devices have been unsuccessful 5) Treatment of non-union, femoral neck fracture, trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques
Device Description
The M²a™/C²a™ Acetabular System consists of a titanium outer acetabular shell with a cobalt alloy metallic liner for metal articulation. The acetabular shells are hemispherical in shape to closely match the natural acetabulum. Two screw holes in the dome allow for additional fixation by the use of screws. The outer surface of the shells are covered with Biomet's plasma sprayed coating. The metallic cobalt alloy bearing liner fits into the outer shell by means of a taper similar to the taper used for the attachment of a modular head to a femoral stem. The metallic liners articulate with cobalt alloy modular heads.
More Information

No
The summary describes a mechanical implant system for hip replacement and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes
The device is an acetabular system, which is a joint implant used to treat degenerative joint diseases and fractures, directly addressing health conditions.

No
The device description indicates it is an acetabular system within a hip joint replacement (prosthetic device), not a tool for diagnosing conditions.

No

The device description clearly states it consists of physical components: a titanium outer acetabular shell and a cobalt alloy metallic liner. This indicates a hardware-based medical device, not a software-only one.

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 surgical implant for treating conditions of the hip joint. This is a therapeutic device, not a diagnostic one.
  • Device Description: The description details a physical implant (acetabular shell and liner) designed to be surgically placed in the body. IVDs are typically reagents, instruments, or systems used to examine specimens from the human body to provide information for diagnosis, monitoring, or treatment.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting substances, or providing diagnostic information.

This device falls under the category of a surgical implant or prosthetic device.

§ 888.3320 Hip joint metal/metal semi-constrained, with a cemented acetabular component, prosthesis.

(a)
Identification. A hip joint metal/metal semi-constrained, with a cemented acetabular component, prosthesis is a two-part 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 consist of a femoral and an acetabular component, both made of alloys, such as cobalt-chromium-molybdenum. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class III.(c)
Date PMA or notice of completion of PDP is required. A PMA or a notice of completion of a PDP is required to be filed with the Food and Drug Administration on or before May 18, 2016, for any hip joint metal/metal semi-constrained prosthesis with a cemented acetabular component that was in commercial distribution before May 28, 1976, or that has, on or before May 18, 2016, been found to be substantially equivalent to a hip joint metal/metal semi-constrained prosthesis with a cemented acetabular component that was in commercial distribution before May 28, 1976. Any other hip joint metal/metal semi-constrained prosthesis with a cemented acetabular component shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

Dear Ms. Andborn Beres:

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. 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 device is classified (see above) into either class II (Special Controls) or class III (PMA), 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 898. In addition, FDA may publish further announcements concerning your device 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 device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
