Surgical implementation of Investigational PeriPulseTM to enable perioperative ES therapy in a digital nerve transection and repair model under either general anesthesia or short-acting local anesthesia. Image background for each panel was digitally removed. A Nerve repair occurs as per standard of care. B Introducer tool is used to create a para-incisional access point for the electrode lead. C Electrode lead is inserted through the introducer tool and placed proximal to the nerve coaptation under visual guidance. The introducer tool is removed. D The electrode lead may be shaped according to the surrounding anatomy to secure placement and prevent shifting of the contacts. Wound closure proceeds as per standard of care. E Signal generator is connected to the electrode lead. Stimulation intensity (mA) is adjusted to the patient’s tolerable range. F 1-hour ES therapy is initiated while the hand is dressed and continues as the patient is transferred to the recovery area. The device system is completely removed and disposed of in the recovery area
