The investigator site file (ISF) contains all essential documents of the clinical trial. It must contain all documents and forms for the investigation site to conduct the clinical trial properly in accordance with the CIP, the applicable regulatory requirements and the principles and standards of GCP. Unlike the TMF, the ISF remains at the investigation site.
investigator's brochure - IB
The investigator's brochure (IB) shall contain the clinical and non-clinical information on the investigational device that is relevant for the investigation and available at the time of application. Any updates to the IB or other relevant information that is newly available shall be brought to the attention of the investigators in a timely manner.
medical device - MD

A medical device can be any instrument, apparatus, appliance, material or other article, whether used alone or in combination, including the software necessary for its proper application, intended by the manufacturer to be used on human beings for the purpose of
