No
The device description and performance studies focus on the mechanical properties and articulation of a physical implant, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes
The device is intended for use in hemiarthroplasty of the hip for conditions like femoral neck and trochanteric fractures and osteonecrosis, which are medical treatments for pathologies.
No
The device is a component of a hip prosthesis system used for surgical replacement, not for diagnosing medical conditions.
No
The device description clearly states it is a physical implantable device made of UHMWPE and stainless steel, intended for surgical use. It is not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the Medacta® Bipolar Head is for use in hemiarthroplasty of the hip. This is a surgical procedure performed directly on the patient's body.
- Device Description: The device is described as a physical implant (UHMWPE liner in a stainless steel shell) designed to articulate within the patient's hip joint.
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not interact with such specimens.
The information provided describes a surgical implant, not a diagnostic test performed on samples outside the body.

Device Description
The Medacta® Bipolar Head consists of a factory assembled Ultra High Molecular Weight Polyethylene (UHMWPE) liner in an outer shell of stainless steel, designed to articulate directly in the patient's actebulum. The inner liner of UHMWPE articulates the prosthetic femoral head. The prosthetic femoral head is locked into place with an elastic retaining ring. The Medacta® Bipolar Head is available in outer diameters from 40 mm to 52 mm in 1 mm increments with an inner diameter that mates with a 22 mm diameter femoral head. The Medacta® Bipolar Head is also available in outer diameters from 44 mm to 60 mm in 2 mm increments with an inner diameter that mates with a 28 mm diameter femoral head. The Medacta® Bipolar Head may be used for hemiarthroplasty in conjunction with the following femoral stems which are part of the Medacta® Hip Prosthesis System - Quadra S, Quadra H and Quadra R stems. (K072857, K082792) The Medacta® Bipolar Heads may be used with the following femoral heads which are part of the Medacta® Hip Prosthesis System - CoCrMo femoral heads - and the ceramic femoral heads called the Mectacer Femoral Heads. (K073337, K080885).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing of the Medacta® Bipolar Head was conducted in accordance with various international standards and FDA guidance documents. The Medacta® Bipolar Head was tested as part of design verification to written protocols with pre-defined acceptance criteria. The testing was conducted on the worst case component size and option/design. The testing met all acceptance criteria and verifies that the performance of the Medacta® Bipolar Head is substantially equivalent to the predicate devices.

(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)
Classification. Class II.

Product Description:
The Medacta® Bipolar Head consists of a factory assembled Ultra High Molecular Weight Polyethylene (UHMWPE) liner in an outer shell of stainless steel, designed to articulate directly in the patient's actebulum. The inner liner of UHMWPE articulates the prosthetic femoral head. The prosthetic femoral head is locked into place with an elastic retaining ring. The Medacta® Bipolar Head is available in outer diameters from 40 mm to 52 mm in 1 mm increments with an inner diameter that mates with a 22 mm diameter femoral head. The Medacta® Bipolar Head is also available in outer diameters from 44 mm to 60 mm in 2 mm increments with an inner diameter that mates with a 28 mm diameter femoral head. The Medacta® Bipolar Head may be used for hemiarthroplasty in conjunction with the following femoral stems which are part of the Medacta® Hip Prosthesis System - Quadra S, Quadra H and Quadra R stems. (K072857, K082792) The Medacta® Bipolar Heads may be used with the following femoral heads which are part of the Medacta® Hip Prosthesis System - CoCrMo femoral heads - and the ceramic femoral heads called the Mectacer Femoral Heads. (K073337, K080885).
The Medacta® Bipolar Head is a product suitable to use in a hemiarthroplasty procedure on any hip joint whose acetabular conditions are satisfactory.
Indications for Use:
The Medacta® Bipolar Head is intended for use in combination with Medacta® Hip Prosthesis System and Mectacer femoral heads for uncemented primary or revision hemiarthroplasty of the hip. This prosthesis may be used for the following conditions, as appropriate:
· Femoral neck and trochanteric fractures of the proximal femur:
- · Osteonecrosis of the femoral head:
· Revision procedures where other devices or treatments for these indications have failed.
Comparison to Predicate Devices
The Medacta® Bipolar Heads have the same indications for use as the predicate, Apex Hip System Bipolar Head (K082468) except for the specific femoral stems and heads with which it works. Medacta® Bipolar Heads are very similar in design, size range, and functionality as all of the bipolar predicates: Apex Hip System Bipolar Head, Ortho Development Pivot Bipolar Head (K050966) and Plus Orthopedics Bipolar Heads (K982447). They all are factory assembled with an UHMWPE liner which is not highly crosslinked. The Medacta® Bipolar Heads' outer metal shell, which is made of stainless steel, is the same type of material used in direct articulation with the natural acetubulum as the Disc-O-Tech Medical Technologies Ltd's Fixion™ Unipolar Modular Hemi-Hip System. Although the Disc-O-Tech predicate device is a unipolar head instead of bipolar head, the Medacta® Bipolar Heads have verv similar indication for use as the Disc-O-Tech predicate device.
