Method, system and device for treating disorders of the pelvic floor by electrical stimulation of the left and the right sacral nerves

A method of treating at least one diagnosed pelvic floor disorder in a patient, the at least one disorder being selected from the group consisting of urinary voiding dysfunction, fecal voiding dysfunction, constipation, stress incontinence, urge incontinence, urinary retention disorder, sexual dysfunction, orgasmic dysfunction, erectile dysfunction, pelvic pain, prostatitis, prostatalgia and prostatodynia, the method comprising:

• providing an hermetically sealed implantable electrical pulse generator configured to provide at least first and second electrical stimulation pulse regimes via at least first and second implantable medical electrical leads;
• providing the first implantable medical electrical lead, the first lead being configured for implantation adjacent a right sacral nerve or branches or portions thereof, the first lead comprising proximal and distal ends and at least a first electrode;
• providing the second implantable medical electrical lead, the second lead being configured for implantation adjacent a left sacral nerve or branches or portions thereof, the second lead comprising proximal and distal ends and at least a second electrode;
• implanting the first lead in or near a first tissue volume of the patient adjacent, around or in one of the left sacral nerve or branches or portions thereof;
• implanting the second lead in or near a second tissue volume of the patient adjacent, around or in one of the right sacral nerve or branches or portions thereof;
• operably connecting the proximal end of the first lead to the implantable pulse generator;
• operably connecting the proximal end of the second lead to the implantable pulse generator;
• implanting the implantable pulse generator within the patient;
• and
• delivering, from the implantable pulse generator, first electrical stimulation pulses to or near at least portions of the first tissue volume through the first lead and at least the first electrode, the first pulses being provided in accordance with the first electrical stimulation pulse regime;
• delivering, from the implantable pulse generator, second electrical stimulation pulses to or near at least portions of the second tissue volume through the second lead and at least the second electrode, the second pulses being provided in accordance with the second electrical stimulation pulse regime;
• wherein the combination of the first and the second electrical pulse regimes delivered through the first and second leads to or near at least portions of the first and second tissue volumes provides to the patient at least partial relief from the pelvic floor disorder.
