This original Investigational Device Application is for a study intended to confirm the safety and efficacy of bilateral subcutaneous median nerve stimulation using the eCoin system to treat resistant hypertension. The eCoin device delivers electrical stimulation pulses to the median nerve from a small coin sized device placed under the skin of the distal anterior forearm. The implant delivers a weekly 30 minute treatment based on previous studies showing a long lasting and cumulative effect. The safety and efficacy of eCoin therapy has previously been demonstrated in a multinational, randomized, double-blind, sham-controlled study in New Zealand, Taiwan and Canada.
