Summary

This study tested a new device called RELAY that delivers both local anesthetic and mild electrical stimulation through a single catheter to control pain after shoulder or foot surgery. Twenty adults who had surgery for rotator cuff tears, shoulder replacement, or foot problems took part. The goal was to see if the device could provide up to 28 days of pain relief, compared to the usual 24-72 hours from standard nerve blocks.
