No
The summary describes a mechanical hip implant system and its components, materials, and performance testing based on established standards. There is no mention of any software, algorithms, or data processing that would suggest the use of AI or ML.
Yes
The device is a Bipolar Cup system used for total or partial hip arthroplasty, which is a medical procedure to treat various degenerative joint diseases and conditions leading to pain and dysfunction. This aligns with the definition of a therapeutic device designed to alleviate or cure a medical condition.
No
The device is a Bipolar Cup system used for total hip arthroplasty, which is a treatment or replacement device, not a diagnostic one. It is implanted to treat various degenerative joint diseases and fractures, not to identify or diagnose them.
No
The device description clearly states it is a system of physical components (femoral stem, femoral head, acetabular system, instrumentation) made of various metal alloys and polyethylene, intended for surgical implantation. There is no mention of software as a component or the primary function of the device.
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 degenerative joint disease and fractures. This is a therapeutic intervention performed in vivo (within the body).
- Device Description: The device is described as a "cementless, metal-on-polyethylene bearing hip system" consisting of physical components like stems, heads, and cups. These are all implantable medical devices.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
IVD devices are used in vitro (outside the body) to analyze biological samples. This device is a surgical implant used in vivo.
