No
The device description focuses solely on the mechanical components and materials of the hip prosthesis. There is no mention of any software, algorithms, or data processing capabilities that would indicate the use of AI or ML. The summary explicitly states the device does not incorporate any new technology.
Yes
The device is indicated for conditions like degenerative joint disease, rheumatoid arthritis, and correction of functional deformity, intending to rehabilitate hip joints through total reconstruction. These uses directly align with the definition of a therapeutic device designed to treat or alleviate a medical condition.
No
This device is a prosthetic system used for total reconstruction of the hip joint. Its purpose is treatment and rehabilitation, not diagnosis.
No
The device description clearly details physical components like femoral heads, acetabular liners, cups, and shells, indicating it is a hardware-based medical device for hip replacement.
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 the surgical reconstruction of the hip joint. This is a therapeutic intervention, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details the physical components of a hip prosthesis (femoral head, acetabular liner, cup, etc.) designed to be implanted in a patient. This is consistent with a surgical implant, not an in vitro diagnostic device.
- Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's condition based on laboratory testing.
In summary, the Tri-Polar System is a surgical implant used for hip replacement, which falls under the category of medical devices, but not In Vitro Diagnostic devices.
N/A
Intended Use / Indications for Use
The Tri-Polar System is indicated for use in patients requiring total reconstruction of the hip joint due to the following:
- a.) Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis
- b.) Rheumatoid arthritis.
- c.) Correction of functional deformity.
- d.) Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques.
- e.) Revision of previously failed total hip arthroplasty due to recurrent dislocations.
The Tri-Polar System is intended for cemented or press-fit application for general use in skeletally mature individuals undergoing surgery for rehabilitating hip joints.

Device Description
The Tri-Polar prosthesis consists of a Bi-Polar femoral head, which articulates with a mating acetabular liner that fits into any standard line acetabular component. Once the Bi-Polar femoral head is used with an acetabular component the device becomes the Tri-Polar.
The Tri-Polar System consists of an all polyethylene or metal backed acetabular cup with a polyethylene liner designed to fit on a Bi-Polar head. The Bi-Polar femoral head component contains a modular head, which is attached to the femoral stem component. In other words, the Tri-Polar system adds an acetabular bearing component to a Bi-Polar hip replacement.
The Tri-Polar liners fit into any currently approved Biomet RingLoc® acetabular shells. The liner is retained in the shell by means of Biomet's standard RingLoc® mechanism. (A current listing of shells is found in Exhibit I). The liner and shell are properly aligned with one another and then locked into position with a metal ring (RingLoc®). The metallic shell has six to eight scalloped semi-circles, which mate with analogous semi-circular cutouts on the liner for prevention of rotation.
Biomet's all polyethylene acetabular cup has two outer concentric rings to facilitate cement interdigitation and an embedded wire for x-ray visualization. The all polyethylene has two outer concentric rings to facilitate cement interdigitation and an embedded wire for x-ray visualization. The all polyethylene acetabular component is intended to be cemented in the aceatabulum or used with a Biomet recovery cage.
The Bi-Polar femoral head consists of a larger outer shell with a polyethylene insert, which contains within it a modular head. The modular head is captured by the polyethylene insert, which is captured by means of a RingLoc® mechanism similar to that previously described above. The 22mm Bi-Polar component c. 1 be used with either size 24 or 25 Tri-Polar liners or the 54, or 57 all polyethylene cup. While the 28mm Bi-Polar component can be used with either size 26, 27, or 28 Tri-Polar liners or the 63, 66, or 69 all polyethylene cup. A polyethylene thickness of 4.0mm is the general standard for a hip prosthesis. The Tri-Polar system utilizes a minimum thickness of 4.8mm, which is greater than the general standard.
The Tri-Polar System does not incorporate any new technology that has not previously been available. The device simply combines this technology.

§ 888.3390 Hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis.
(a)
Identification. A hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis is a two-part device intended to be implanted to replace the head and neck of the femur. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a snap-fit acetabular component made of an alloy, such as cobalt-chromium-molybdenum, and ultra-high molecular weight polyethylene. This generic type of device may be fixed to the bone with bone cement (§ 888.3027) or implanted by impaction.(b)

SUBSTANTIAL EQUIVALENCE:
The Tri-Polar Acetabular System is similar to previously marketed devices. The device is similar to a traditional hip device consisting of a femoral stem, modular head, and metal backed polyethylene component, with the addition of a Bi-Polar bearing surface between the modular head and acetabular bearing surface.

Dear Ms. McKinley:
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 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 (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.
