The purpose of this Funding Opportunity Announcement (FOA) is to encourage applications to pursue translational and clinical studies for therapeutic devices to treat neurological disorders. The program will utilize a cooperative agreement mechanism to support the submission of an Investigational Device Exemption (IDE) or IRB approval for a Non-Significant Risk (NSR) study and the following clinical study. It is expected that the clinical study will inform a final device design that would have to go through most, if not all, of the preclinical testing on the path to more advanced clinical trials and market approval. This program also supports development of a device to test scientific hypotheses that are not feasible or practical to conduct in animal models, but are critical to enable next-generation devices. Activities supported in this program include implementation of clinical prototype devices, preclinical safety and efficacy testing, design verification and validation activities, pursuit of regulatory approval for the clinical study, and a small clinical study.
