Intended Use

The MyoTrac Infiniti system is indicated for acute and ongoing treatment of stress, urge or mixed urinary incontinence and where the following results may improve urinary control: Inhibition of the detruser muscle through reflexive mechanisms, strengthening of pelvic floor muscle. It is also indicated during incontinence treatment for assessing EMG activity of the pelvic floor and accessory muscles such as the abdominal or gluteal muscles. The MyoTrac Infiniti system is also indicated for the ongoing treatment of the following conditions: Relaxation of Muscle Spasms, Prevention or retardation of disuse atrophy, increasing local blood circulation, immediate post-surgical stimulation of calf muscles to prevent venous thrombosis, Maintaining or increasing range of motion and Stroke Rehab by Muscle re-education. It is also used for Biofeedback, Relaxation & Muscle Re-Education purposes.

Device Story

MyoTrac Infiniti is a non-implanted electrical muscle stimulator and electromyography (EMG) device. It inputs bioelectric signals via vaginal or rectal EMG/stimulation sensors; processes signals using Root Mean Square (RMS) calculations; and outputs stimulation pulses or visual biofeedback (line graphs, bar graphs, digital displays, animations). Used in clinical settings by healthcare providers for pelvic floor muscle re-education, incontinence treatment, and neuromuscular rehabilitation. Providers monitor EMG activity to guide therapy; stimulation parameters (frequency, intensity, pulse width) are adjustable by clinicians, with optional feature locking for patient safety. Benefits include improved urinary control, muscle strengthening, and rehabilitation of muscle function.

Clinical Evidence

Bench testing only. Evidence consists of verification of product specifications, system validation, safety testing, and EMC testing. Biocompatibility of patient-contacting electrodes (vaginal/rectal sensors) was confirmed through laboratory testing against applicable standards.

Technological Characteristics

Non-implanted electrical stimulator and EMG biofeedback device. Features bipolar EMG detection with RMS signal processing. Stimulation parameters: 12.5-200 Hz frequency, 0-100mA intensity, 0.2-1ms pulse width. Connectivity includes vaginal/rectal sensors. Powered by 1.5V battery or medical Class II power adapter. Software performs signal processing and display of biofeedback data.

Indications for Use

Indicated for patients requiring treatment for stress, urge, or mixed urinary incontinence; muscle spasms; disuse atrophy; poor local blood circulation; post-surgical venous thrombosis prevention; range of motion maintenance; or stroke rehabilitation. Used for EMG biofeedback and muscle re-education.

Regulatory Classification

Identification

A nonimplanted electrical continence device is a device that consists of a pair of electrodes on a plug or a pessary that are connected by an electrical cable to a battery-powered pulse source. The plug or pessary is inserted into the rectum or into the vagina and used to stimulate the muscles of the pelvic floor to maintain urinary or fecal continence. When necessary, the plug or pessary may be removed by the user. This device excludes an AC-powered nonimplanted electrical continence device and the powered vaginal muscle stimulator for therapeutic use (§ 884.5940).
