The document describes a hip implant and its components, focusing on materials, sizes, and mechanical testing for MR compatibility. There is no mention of AI or ML in the intended use, device description, or performance studies.
Yes.
The device, a Hip Stem, is used in procedures like hip arthroplasty to treat painful and disabling joint diseases, correct functional deformities, and manage fractures, directly addressing and alleviating medical conditions which is a therapeutic purpose.
No
Explanation: The device described is a hip stem (prosthetic implant) used for hip arthroplasty procedures, which is a therapeutic device, not a diagnostic one. Its purpose is to replace part of the hip joint.
No
The device description clearly states that the device is a sterile, single-use physical implant made of Ti6Al4V ELI alloy with a hydroxyapatite coating. It is intended for cementless fixation into a prepared femoral canal. This is a hardware device, not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The intended use clearly describes a surgical implant for hip arthroplasty, addressing painful joint disease, revisions, deformities, and fractures. This is a therapeutic intervention, not a diagnostic test performed in vitro (outside the body).
- Device Description: The device is described as a sterile, single-use hip stem made of Ti6Al4V ELI alloy with a hydroxyapatite coating, designed for cementless fixation into the femoral canal. This is a physical implant, not a reagent, instrument, or system intended for use in the examination of specimens derived from the human body.
- No mention of diagnostic testing: The text focuses entirely on the surgical application and performance of the implant within the body. There is no mention of analyzing biological samples or providing diagnostic information.
- Performance Studies: The performance studies described are related to the device's behavior in an MR environment (displacement force, torque, image artifact, heating), which are relevant to the safety and compatibility of a surgical implant, not the accuracy of a diagnostic test.
In summary, the device is a surgical implant used for hip replacement, which falls under the category of medical devices used for treatment or restoration of function, not for in vitro diagnosis.
