A therapeutic device is one that treats a disease or condition. The ProxiLock Hip Prosthesis is a replacement for a degenerated hip joint, which serves a therapeutic purpose by alleviating symptoms and restoring function. However, within the context of medical device classifications, a "therapeutic device" typically refers to devices that directly intervene to treat a disease, such as drug delivery systems, surgical instruments used for active treatment, or devices that apply energy to tissue. A prosthesis, while restoring function and addressing a pathology, is more accurately classified as a restorative or reconstructive device rather than a "therapeutic device" in the strict sense of direct treatment application.
No
Explanation: The device described is a hip prosthesis, an implant used for surgical reconstruction of the hip joint. Its purpose is to replace or support a diseased or damaged joint, not to diagnose a condition.
No
The device description clearly describes a physical hip prosthesis (stem) made of material, intended for surgical implantation, and subject to mechanical testing. This is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- Device Description: The ProxiLock Hip Prosthesis is a physical implant designed to replace a damaged hip joint. It is surgically implanted into the patient's body.
- Intended Use: The intended use is to treat severe degeneration of the hip joint through surgical implantation.
- No Mention of Samples or Testing: The description does not mention any testing of biological samples or providing diagnostic information based on such tests.
Therefore, the ProxiLock Hip Prosthesis is a surgical implant, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The ProxiLock Hip Prosthesis is intended for use where severe degeneration of the hip joint is necessary due to osteoarthritis, rheumatoid arthritis, trauma, revision of previously failed total hip arthroplasty or other pathology.

Device Description
The ProxilLock Hip Prosthesis offers the surgeon a cementless option in reconstructing the hip joint on the femoral side. The stem is intended for use in the relatively younger, moderate and higher demand patient in hybrid or cementless hip arthroplasty. The Implex ProxiLock Hip Prosthesis is compatible with all Implex acetabular Hip components. The ProxiLock Hip Prosthesis is available in an array of sizes to fit a patient size range. The stem system is available without a distal slotted stem. The ProxiLock Stem is intended to be used as a cementless stem only, and is intended to cooperate with Implex Femoral Bearing Heads via a tapered locking mechanism between the neck of the ProxiLock Hip Prosthesis and the Modular Bearing Head. Implex Modular Bearing Heads are compatible with all Implex Femoral Stems.

§ 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.
