Electro-stimulation systems and methods for rehabilitation and treatment of sexual disorders

An implantable system for treating erectile dysfunction, the system comprising:

• a flexible paddle having an array of electrodes comprising at least two rows of electrodes and at least two columns of electrodes;
• and
• a programmable controller comprising a stimulation circuit, a microprocessor and a memory, the stimulation circuit operatively coupled to the array, the microprocessor configured to execute programmed instructions stored in the memory to:
• cause the stimulation circuit to selectively activate a first pair of electrodes of the array to create a first current flow therebetween in a first direction, the first current flow configured to stimulate a cavernous nerve to elicit a first erectile response;
• cause the stimulation circuit to selectively activate a second pair of electrodes of the array to create a second current flow therebetween in a second direction, the second direction different than, and oblique to, the first direction, the second current flow configured to stimulate the cavernous nerve to elicit a second erectile response;
• identify either the first erectile response or the second erectile response as a first preferred erectile response;
• and
• store an identity of either the first direction or the second direction as a preferred current direction for subsequent stimulation of the cavernous nerve.
