No
The description focuses on electrical stimulation parameters and hardware components, with no mention of AI/ML terms or functionalities.
Yes
The device is described as a "Powered Muscle Stimulator" and the intended uses are for therapeutic purposes such as "Maintaining or increasing range of motion of the knee joint," "Prevention or retardation of disuse atrophy," "Muscle re-education," "Relaxation of muscle spasms," and "Increasing local blood circulation."
No
The provided text describes the device's indications for use as therapeutic (e.g., maintaining range of motion, preventing atrophy, muscle re-education, relaxing spasms, increasing blood circulation), not for diagnosing conditions.
No
The device description explicitly lists hardware components such as a Controller, Interconnect Cable, Stimulation Array Pads, and Power Cord, and mentions hardware validations in the performance studies summary.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions.
- Device Description and Intended Use: The provided information clearly describes a device that applies electrical stimulation externally to the quadriceps muscle. Its intended uses are related to physical therapy and rehabilitation, such as maintaining range of motion, preventing muscle atrophy, and reducing spasms.
- Lack of Biological Sample Analysis: There is no mention of the device analyzing any biological samples from the patient.
The device is a Powered Muscle Stimulator, which is a type of physical medicine device, not an in vitro diagnostic device.

Device Description
The Muscle Stimulation System 110 is a portable, externallypowered device which provides electrical stimulation to the quadriceps using constant current pulses. The device is a Powered Muscle Stimulator per 21 CFR § 890.5850 (Product Code: IPF). Pulses are delivered via six independently controlled stimulation channels (3 per leg) and are provided to the patient via electrodes integrated into disposable Stimulation Array Pads. An Interconnect Cable allows for communication between the System Controller and Stimulation Array Pads.
The major components of the system consist of a Controller, an Interconnect Cable, a pair of disposable Stimulation Array Pads configured for application to the quadriceps of a patient, a Power Cord, and instructions for use.
