The device is described as an electrical stimulation device for therapeutic purposes (e.g., muscle relaxation, re-education, pain relief, incontinence treatment), and while it uses EMG biofeedback, it mentions assessing EMG activity rather than making a diagnosis. The primary functions listed are for treatment and management, not for diagnosing a condition.
No
The device description explicitly states it is a "four-channel, hand-held, non-sterile, battery-powered, multi-patient device" and mentions hardware components like a MCU, display, Bluetooth, audio, and a wireless charger. It is a physical electrical stimulation device controlled by software, not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The Medline DeNovo 4Pro Electrical Stimulation Device is an external electrical stimulation device that applies electrical currents to the body through electrodes or a probe. It is used for therapeutic purposes like muscle stimulation, pain management, and incontinence treatment.
- Lack of Specimen Analysis: The device does not analyze any biological specimens from the patient. Its function is based on applying electrical signals to the body.
The intended uses and device description clearly indicate that this is a therapeutic device, not a diagnostic one that analyzes samples.

Device Description
The Medline DeNovo 4Pro Electrical Stimulation Device is a four-channel, hand-held, non-sterile, battery-powered, multi-patient device intended to be used by adult patients under the supervision of a trained clinical healthcare provider. The proposed device is controlled by a MCU (Microcontroller Unit) that supports device functionality, display functionality. Bluetooth, and audio. The subject device is intended to be used for muscle stimulation for the purposes of urinary incontinence treatment, pain management, muscle strengthening and training, as well as muscle relaxation and re-education. The device is a TENS (Transcutaneous Electrical Nerve Stimulator), ETS (Electrical Muscle Stimulator) and NMES (Neuromuscular Electrical Stimulator also known as STIM) including FES (Functional Electrical Stimulation) with EMG biofeedback.
The Medline DeNovo 4Pro Electrical Stimulation Device features four channels for NMES (Neuromuscular Electrical Stimulator also known as STIM), with two that utilize Electromyography (EMG). Multiple stimulation protocols are pre-programed for three general categories of applications: muscle strengthening (i.e. biofeedback training), pain control, and neuromuscular re-education. Each category contains up to eight protocols to address the specific needs of the patient.
The Medline DeNovo 4Pro Electrical Stimulation Device is designed to provide safe and effective electrical stimulation by sending small electrical currents to underlying nerves and muscle groups via electrodes applied on the skin or through a vaginal probe (for incontinence treatment protocols only). The parameters of the unit are controlled by the +/- push buttons and touch screen (refer to Figure 1 and 2 below). The pre-programed protocols on the Medline DeNovo 4Pro Electrical Stimulation Device are all fully automatic and controlled by the device, and it is also capable of manual control in hand switch mode. The levels of intensity are adjustable to the needs of the patient and treatments prescribed by their healthcare providers. The device can be used with or without linkage to a PC and includes a color, pressure sensitive touch-screen. This unit also comes with a wireless charger that is capable of charging during NMES (Neuromuscular Electrical Stimulator also known as STIM) via inductive charging. Batteries will not need to be regularly replaced, and charging will be made so much easier. The proposed device also has Bluetooth capabilities that will allow the device to connect to a computer for screen mirror imaging.

Device Description
The Medline DeNovo 4Pro Electrical Stimulation Device is a four-channel, hand-held, non-sterile, battery-powered, multi-patient device intended to be used by adult patients under the supervision of a trained clinical healthcare provider. The proposed device is controlled by a MCU (Microcontroller Unit) that supports device functionality, display functionality. Bluetooth, and audio. The subject device is intended to be used for muscle stimulation for the purposes of urinary incontinence treatment, pain management, muscle strengthening and training, as well as muscle relaxation and re-education. The device is a TENS (Transcutaneous Electrical Nerve Stimulator), ETS (Electrical Muscle Stimulator) and NMES (Neuromuscular Electrical Stimulator also known as STIM) including FES (Functional Electrical Stimulation) with EMG biofeedback.
The Medline DeNovo 4Pro Electrical Stimulation Device features four channels for NMES (Neuromuscular Electrical Stimulator also known as STIM), with two that utilize Electromyography (EMG). Multiple stimulation protocols are pre-programed for three general categories of applications: muscle strengthening (i.e. biofeedback training), pain control, and neuromuscular re-education. Each category contains up to eight protocols to address the specific needs of the patient.
The Medline DeNovo 4Pro Electrical Stimulation Device is designed to provide safe and effective electrical stimulation by sending small electrical currents to underlying nerves and muscle groups via electrodes applied on the skin or through a vaginal probe (for incontinence treatment protocols only). The parameters of the unit are controlled by the +/push buttons and touch screen (refer to Figure 1 and 2 below). The pre-programed protocols on the Medline DeNovo 4Pro Electrical Stimulation Device are all fully automatic and controlled by the device, and it is also capable of manual control in hand switch mode. The levels of intensity are adjustable to the needs of the patient and treatments prescribed by their healthcare providers. The device can be used with or without linkage to a PC and includes a color, pressure sensitive touch-screen. This unit also comes with a wireless charger that is capable of charging during NMES (Neuromuscular Electrical Stimulator also known as STIM) via inductive charging. Batteries will not need to be regularly replaced, and charging will be made so much easier. The proposed device also has Bluetooth capabilities that will allow the device to connect to a computer for screen mirror imaging.
How Device Achieves its Intended Purpose:
-
. TENS
TENS uses the proposed battery operated unit to provide a non-invasive, low-risk nerve stimulation in order to reduce pain (both acute and chronic). In TENS, mild electrical impulses are transmitted through the skin via surface electrodes to relieve muscle pain by modifying the body's pain perception. TENS does not cure problematic physiological conditions; it only helps to control the pain perception. -
NMES (also known as STIM) ● NMES is the elicitation of muscle contraction using electric impulses. The impulses are
6
generated by a device and delivered through the electrodes in direct proximity to the muscles to be stimulated or via the vaginal probe. The impulses mimic the action potential coming from the central nervous system, causing the muscles to contract. NMES is both a form of electrotherapy and of muscle training. Neuromuscular Stimulation has been used to stimulate muscle and nerve fibers for muscle strengthening, maintenance of muscle mass and strength during prolonged periods of immobilization, selective muscle retraining, and the control of edema.
● FES
FES is the process of combining electrical stimulation with a functional task such as walking. This is a treatment that applies small electrical charges to the leg to improve mobility in people who have difficulties with walking. As well as being a treatment for foot drop, FES can also be used in rehabilitation, complementing physiotherapy techniques, often to assist with movements in muscles that have become weak. This allows the user to build strength and range of movement.
Surface electromyography (EMG) ● EMG is a technique for evaluating and recording the electrical activity produced by skeletal muscles. Surface EMG is used for recording from superficial muscles in clinical or kinesiological protocols, where intramuscular electrodes are used for investigating deep muscles or localized muscle activity.
. ETS
ETS involves initiating a voluntary contraction for a specific movement until the muscle activity reaches a threshold level. This treatment is especially useful for stroke rehabilitation and pelvic muscle improvement. As soon as the EMG activity reaches a target threshold then an assisting electrical stimulus begins which helps to support the contracted muscle. A microprocessor connected to the surface electrodes or vaginal probe monitors the EMG activity levels as well as administers the neuromuscular stimulation. The Target threshold could be set to automated regime, when it goes up and down depending on the running muscle performance.
