Indications for Use
This device is intended as therapeutic aid in the conservative treatment of stress incontinence, urge incontinence or mixed stress and urge incontinence in women. Patients appropriate for this therapy should be selected using the following criteria: Indications: - Good general health, both mentally and physically. - Urge incontinence due to detrusor instability or of idiopathic origin. - Stress incontinence not associated with intrinsic sphincter deficiency. - Mixed incontinence. - Ability of patient to understand and demonstrate understanding of the use of the Liberty Plus System. - Willingness to comply with the therapy plan. Contraindications: - Use of a cardiac pacemaker, or a history of rate or conductive disturbances. - Neurological deficiency that would not permit proper sensory perception or stimulation. - Currently pregnant or attempting to get pregnant. - Anatomical vaginal structure that does not permit proper and complete placement of the vaginal probe. - Irregular menstrual bleeding cycles. - Any urinary or vaginal infections, localized lesions or other undiagnosed symptoms. - History of urinary retention or current symptoms.
Device Story
Liberty Plus System (PFS-300) is a battery-powered electrostimulation and biofeedback device for pelvic floor muscle training. Input: pressure signals from vaginal applicator (PFS-044) during muscle contractions. Operation: handheld unit delivers electrical stimulation to pelvic floor via stainless steel electrodes on applicator; simultaneously processes pressure transducer signals. Output: oscillographic biofeedback on LCD graphical display. Usage: prescribed for women to restore/improve urinary continence. Healthcare provider uses output to monitor therapy progress; patient uses biofeedback to guide muscle contractions. Benefits: non-invasive neuromuscular training for incontinence management.
Clinical Evidence
Bench testing only. Laboratory tests demonstrated equivalent electrical stimulation of pelvic floor muscles compared to the PFS-200 and equivalent pressure reading capabilities compared to the Cardio Design PFX.
Technological Characteristics
Handheld electrostimulation unit with injection-molded thermoplastic vaginal applicator. Features two stainless steel electrode rings and a pressure transducer. Energy source: battery-powered. Connectivity: six-conductor cable between applicator and unit. Display: LCD graphical display for oscillographic output. Materials: biocompatible. Operation: electrical stimulation and pressure-based biofeedback.
Indications for Use
Indicated for women with stress, urge, or mixed urinary incontinence. Patients must be in good general health, capable of understanding device use, and willing to comply with therapy. Contraindicated for patients with cardiac pacemakers/conduction disturbances, neurological sensory deficits, pregnancy, anatomical vaginal abnormalities, irregular menstrual cycles, active infections/lesions, or history of urinary retention.
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).
