More Information

Not Found

Not Found

No
The summary does not mention AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices. The intended use and anatomical site suggest a device for muscle stimulation, which is a common non-AI application.

Yes
The indications for use describe conditions that would be treated or prevented by the device, such as muscle disuse atrophy, muscle spasms, and venous thrombosis. These are therapeutic applications.

No
The device's indications for use describe therapeutic applications (prevention/retardation of atrophy, increased blood flow/range of motion, prevention of venous thrombosis, relaxation of spasms), not the diagnosis of a condition.

Unknown

The provided text only describes the intended use and anatomical site. It lacks a device description, which is crucial for determining if the device is software-only or includes hardware components.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended uses listed (prevention and retardation of muscle disuse atrophy, increase local blood flow, increase range of motion, prevent venous thrombosis with immediate postsurgical stimulation of calf muscles; relaxation of muscle spasms) are all related to treating or affecting the body directly. IVDs are used to examine specimens (like blood, urine, or tissue) outside the body to provide information about a person's health.
  • Device Description: While the description is "Not Found," the intended use clearly points to a device that interacts with the body, not a laboratory test.
  • Anatomical Site: The mention of "calf muscles" further reinforces that this device is applied to the body.

Therefore, this device falls under the category of a therapeutic or physical medicine device, not an in vitro diagnostic device.
