No
The description focuses on the mechanical design, materials, and intended use of a hip implant system. There is no mention of AI or ML in the device description, intended use, or performance studies.
Yes
The device is indicated for the reduction or relief of pain and/or improved hip function, and conditions listed under its indications for use involve health issues that the device aims to treat or correct.
No
This device is a hip arthroplasty component designed for surgical implantation to replace part of a hip joint, not to diagnose a condition.
No
The device description clearly details physical components made of metallic alloys and plastic, which are implanted during surgery. 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 hip replacement, addressing conditions like osteoarthritis, avascular necrosis, and fractures. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details the physical components of a hip prosthesis (metallic outer shell, plastic liner, femoral head) and its assembly for surgical implantation. This is consistent with a medical device used in vivo (within the body).
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
In summary, this device is a surgical implant used to treat hip conditions, which falls under the category of a medical device, not an In Vitro Diagnostic device.

- Non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, 1. ankylosis, protrusio acetabuli, and painful hip dysplasia;
- Inflammatory degenerative joint disease such as rheumatoid arthritis; 2.
- Correction of function deformity; 3.
- Revision procedure where other treatments or devices have failed; and 4.
- Treatment of nonunion, femoral neck, and trochanteric fractures of the proximal femur 5. with head involvement that are unmanageable using other techniques.

Device Description
The U1 Hip system - Bipolar is designated as a hemiarthroplasty component and is to be used with United U1 hip stem (K994078) and U2 hip stem (K003237) of total hip replacement. It is a modular type of product system. The U1 Hip system - Bipolar has 23 sizes (40-62 mm in 1 mm increments) of option with a hemispherical design, easy snap-in and take out mechanism. The metallic outer shell is produced from casting Co-Cr-Mo alloy (ASTM F75). The plastic liner with a 26 mm inner diameter is machined from extruded UHMWPE bars (ISO 5834/1). The U1 26 mm femoral head (K994078) has four different neck lengths (+0, +3, +6, +9 mm), which can meet the various needs of patient. The inner femoral head will be pressed into the polyethylene liner firstly, and then the polyethylene liner with inner head will be pressed into the outer shell using a bipolar head assembly device in the operating room.

Summary of Performance Studies
The U1 Hip system- Bipolar is similar to currently marketed bipolar systems. The maximum range of motion between the inner bearing liner and the hip stem exceeds 60 degrees in flexion. In addition, positive eccentricity design allows optimal transmission of load from the acetabular cup to the femoral head. A review of the mechanical test data indicated that the locking strength of this Bipolar system is strong enough to prevent locking mechanism failure in clinical use.

(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)
