New device could provide weeks of pain relief after surgery without opioids

This study is testing a new medical device called RELAY that aims to better control pain after shoulder or foot surgery. The device combines a standard local anesthetic injection with a small electrical current delivered through the same tiny tube, potentially providing pain relief for up to 28 days. Researchers are comparing the device's active electrical stimulation to a sham (fake) version in 50 patients to see if it reduces pain and opioid use after surgery.
