DuoMAG rPMS: MagChair for magnetic stimulation of the pelvic floor

How DuoMAG rPMS Works

Involuntary pelvic floor muscle contractions induced by magnetic stimulation, without voluntary effort by the patient.

DuoMAG rPMS combines the DuoMAG XT stimulator with the MagChair for repetitive peripheral magnetic stimulation (rPMS) of the pelvic floor. The stimulation coil is integrated directly in the seat of the MagChair: the patient remains seated during stimulation while the coil stays in a fixed position. The magnetic field reaches deep neuromuscular structures without invasive electrodes and induces involuntary contractions of the pelvic floor muscles.

Indications and Use

Urinary incontinence MDR-certified indication: urinary incontinence (stress, urge, mixed). Apart from the contraindications listed in the Safety and Performance Information, no limitations by sex, age or weight apply to the intended patient population.
Deep neuromuscular activation Magnetic fields reach deep neuromuscular structures without invasive electrodes. Depolarization of motor nerves induces involuntary contractions of the pelvic floor muscles, which participate in the urethral closure mechanism.
Controlled and repeatable stimulation The DuoMAG software lets you create, save and run a stimulation protocol with adjustable intensity, so that pelvic floor muscle engagement during the session is controlled and reproducible.
Patient comfort and privacy The non-invasive extracorporeal approach supports patient comfort, privacy and treatment acceptance.
Safety and tolerability Non-invasive extracorporeal stimulation, with no electrodes in contact with mucosa. Contraindications, warnings and possible undesirable effects are listed in the Safety and Performance Information and the Instructions for Use.

DEYMED Technological Advantages

Coil in the seat The 140U-LQC stimulation coil is integrated directly in the seat of the MagChair and held in a fixed position during stimulation.
Cooled coil DuoMAG liquid cooling with built-in sensors protects the coil from overheating and enables continuous repetitive stimulation.
Precise patient positioning The height-adjustable seat (420–550 mm), sliding backrest and mechanically lockable armrests allow precise patient positioning.
Stimulation protocols The DuoMAG software allows you to create, save and execute a stimulation protocol with customizable stimulation intensity.
Non-woven textile holder The roll (up to 50 cm wide) is always at hand, so patient changeover is quick and hygienic.
Stable and mobile The chair frame is designed for a load of 150 kg. The chair is fitted with braked castors.
