Sponsor means the entity that takes responsibility for and initiates a clinical investigation. The sponsor can be any legal entity, including a company, an academic organization, or an individual. (Note: the sponsor is often but not always the entity that funds the clinical research.)
Sponsor-Investigator means an individual who both initiates and conducts the clinical investigation and under whose immediate direction the investigational device is being administered, used, or dispensed. The sponsor-investigator assumes all of the responsibilities of the sponsor as well as all the responsibilities of an investigator as outlined in the regulations.
Unanticipated Adverse Device Effect (UADE) - Any serious adverse effect on health or safety or any life-threatening problem or death caused by, or associated with, a device if that effect, problem, or death was not previously identified in nature, severity, or degree of incidence in the investigational plan or application (including a supplementary plan or application), or any other unanticipated serious problem associated with a device that relates to the rights, safety, or welfare of subjects.
