It has been discovered that pain felt in a given region of the body can be treated, not by motor point stimulation of muscle in the local region where pain is felt, but by stimulating muscle spaced from a “nerve of passage” in a region that is superior (i.e., cranial or upstream toward the spinal column) to the region where pain is felt. Spinal nerves such as the intercostal nerves or nerves passing through a nerve plexus, which comprise trunks that divide by divisions and/or cords into branches, comprise “nerves of passage.”

Systems and methods treat hemorrhoids by introducing a treatment device into the anal canal to extend above a hemorrhoidal plexus and adjacent a tissue region containing blood vessels that feed the hemorrhoidal plexus. The systems and methods operate the treatment device to affect tissue morphology in the tissue region to occlude or otherwise reduce blood flow through the vessels.

Recovery from peripheral nerve and nerve plexus injuries is usually slow and incomplete because the regenerating motor axons often head erroneously toward sensory receptors rather than muscle fibers and because the target muscles atrophy while waiting for the slow process of reinnervation. Research has suggested that electrical stimulation with different waveforms and temporal patterns at different times during the regeneration process might improve the clinical outcome through various mechanisms, but a practical means to deliver such stimulation has been lacking. This invention teaches the use of miniature electrical stimulators that can be implanted alongside the injured nerve(s) at the time of surgical repair and that can be powered and controlled by transmission of radiofrequency energy from outside the body so as to provide a variety of electrical stimuli at different times during the recovery process.
