Anal probe with 4 electrodes for perineal ?re-education, through EMG biofeedback and electrostimulation Intended for the treatment of male patients with post-prostatectomy urinary incontinence or patients with defecatory disorders. The depth of insertion is adjustable, from 40 to 55 mm, according to the anatomical constitution of the patient, by means of the rear flange with 4 positions which also determines the correct orientation of the probe. The 4 electrodes (2 front and 2 rear) can be connected to two separate channels of the electromedical apparatus or to a single channel (through special "Y"-shaped optional wire adaptors). The type of connection of the 4 electrodes allows to selectively treat the puborectalis muscle and the internal anal sphincter. The end of the probe, which is intended to go beyond the anal sphincter to be inserted in the rectal bulb, has a spheroidal shape which is appropriately flattened to limit interference with an enlarged prostate in the treatment of male patients with benign prostatic hypertrophy (BPH). The PERISPHERA® perineal probes are made entirely of biocompatible plastic material, with gold plated metalized electrodes. The electrical connection with the stimulation or the EMG-biofeedback unit is obtained by two or four wires (about 20 cm in length) with a 2mm female banana ending. The probe can be used with any equipment supplying symmetric biphasic pulses, zero average value (galvanic-free). Each probe is supplied unsterilized in a single sealed bag, placed in individual box containing the package leaflet with instructions for use.
