Early Feasibility Study of the Nervive VitalFlow Stimulation for Acute Ischemic Stroke Patients

Withdrawn before enrolling · Not applicable

Conditions studied: Acute Stroke

In brief

This Early Feasibility Study (EFS) is a multi-center, open-label single-arm study in 10 acute ischemic stroke (AIS) patients treated with VitalFlow-IS stimulation within 6 hours of symptom onset. The purpose of the EFS is to evaluate initial clinical safety and device functionality in the clinical workflow setting for treatment of acute ischemic stroke patients that will inform design modifications and/or user interface in preparation for next steps consisting of (1) a full safety/feasibility clinical study and (2) randomized controlled pivotal trial with a surrogate endpoint (expedited Premarket Approval (PMA) pathway).
