Abstract: Miniature implantable stimulators (i.e., microstimulators) are capable of producing unidirectionally propagating action potentials (UPAPs). The methods and configurations described may, for instance, arrest action potentials traveling in one direction, arrest action potentials of small diameters nerve fibers, arrest action potentials of large diameter nerve fibers. These methods and systems may limit side effects of bidirectional and/or less targeted stimulation.

Abstract: Methods of using unidirectionally propagating action potentials (UPAPs) for cavernous nerve stimulation and for certain disorders are provided. Stimulators capable of creating such UPAPs include, but are not limited to, miniature implantable stimulators (i.e., microstimulators), possibly with programmably configurable electrodes.
