No
The description mentions a "microprocessor-controlled knee joint system with hydraulic stance and swing phase control" and "immediately adapts to different walking speeds," but it does not explicitly mention AI or ML. The adaptation is likely based on pre-programmed algorithms and sensor data, not learning from data.
No.
The device description indicates it is a component of a prosthesis, specifically a microprocessor-controlled knee joint system, which is a replacement for a missing body part, not a device for treating a disease or condition.
No
The device description clearly states "C-LEG (3C100) is a microprocessor-controlled knee joint system with hydraulic stance and swing phase control." It is a prosthetic device designed to aid movement, not to diagnose a medical condition.
No
The device description explicitly lists multiple hardware components including a carbon fiber frame, hydraulics with servo motor, electronics, and various adapters and accessories. While software is mentioned ("4X70 Slider Software"), it is listed as an accessory to a physical knee joint system.
No, 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, tissue) to provide information about a person's health.
- Device Description: The C-LEG (3C100) is a prosthetic knee joint system. It is a mechanical and electronic device designed to replace a missing lower limb.
- Intended Use: The intended use is the "Fitting of lower limb prosthesis" and providing "stance stability" for individuals with lower limb amputations. This is a functional replacement, not a diagnostic test.
The device description and intended use clearly indicate that the C-LEG is a prosthetic device used to aid mobility and stability, not to diagnose or provide information about a medical condition through testing of bodily samples.

Dear Mr. Hendrickson:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
