The description focuses on the material and mechanical properties of a physical implant, with no mention of software, algorithms, or data processing.
Yes
The device is intended to relieve hip pain and restore hip motion in patients with various conditions affecting the natural femoral head and neck, which are therapeutic functions.
No
Explanation: The device is a prosthetic femoral head intended for hip arthroplasty to relieve pain and restore motion, not to diagnose medical conditions.
No
The device description clearly states it is fabricated from physical materials (CoCrMo and Ti-6A1-4V) and is a physical implantable device (femoral head and modular neck length sleeve). It is not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The provided text describes a surgical implant (a femoral head and neck sleeve) used in hip replacement surgery. It is a physical device implanted into the patient's body.
- Intended Use: The intended use is to treat patients with hip conditions by replacing the damaged femoral head and neck. This is a therapeutic intervention, not a diagnostic test.
The description clearly indicates a device used in vivo (within the living body) for surgical treatment, not a test performed in vitro (outside the living body) for diagnosis.

Intended Use / Indications for Use
The Foundation® Unipolar femoral head is intended for treatment of patients who are candidates for hemi-hip arthroplasty because the natural femoral head and neck have been affected by osteoarthritis, inflammatory arthritis, traumatic arthritis, rheumatoid arthritis, avascular necrosis of femoral neck fracture, and revision arthroplasty where bone loss is minimal. These devices are intended to aid the srugeon in relieving the patient of hip pain and restoring hip motion and are intended to be used with any stem that has the appropriate size head. This submission includes the unipolar femoral head with a modular neck length sleeve.

Device Description
The Foundation® Unipolar headis fabricated from cast CoCrMo that conforms to ASTM F795. The modular neck length sleeve is fabricated from Ti-6A1-4V that conforms to ASTM F136.
This device is assembled by the surgeon at the time of implantation. The sleeve is placed on the taper of the femoral component and impacted into place. Next the unipolar head is placed on the taper and using the impactor is locked into place.
The unipolar head may be used with any stem that has the appropriate Morse Taper.

§ 888.3360 Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis.
(a)
Identification. A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth.(b)
Classification. Class II.
