No
The 510(k) summary describes a mechanical knee implant system and its performance testing, with no mention of AI or ML technology.
Yes
The device is a knee joint prosthesis intended for unicompartmental knee arthroplasty to treat painful osteo or post-traumatic arthritis, revise unsuccessful surgical procedures, or serve as an alternative to tibial osteotomy for unicompartmental osteoarthritis. These uses directly alleviate or treat medical conditions, fitting the definition of a therapeutic device.
No
The device is a knee joint femorotibial (unicompartmental) prosthesis used for unicompartmental knee arthroplasty, not for diagnosing medical conditions.
No
The device description explicitly states it is a knee joint prosthesis consisting of physical components (metal tibial tray, polyethylene tibial insert, metal femoral component). The performance studies also focus on the physical properties and performance of these hardware components.
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 treating knee joint conditions. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details the components of a knee prosthesis (tibial tray, insert, femoral component), which are physical implants used in surgery.
- Lack of Diagnostic Function: There is no mention of the device being used to analyze samples (blood, tissue, etc.) or provide diagnostic information about a patient's condition.
- Clinical Testing: The clinical testing section focuses on the performance and safety of the implant itself, not on its ability to diagnose.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.
