I am a software developer at a small startup and we are currently working on developing the software as part of an integrated device. The device is used to collect and analyze patient data in clinical studies. We have had the first version of the software released, and are currently working on changing the spftware for a different indication of use, and the only changes we will be making are minor labeling changes on the GUI. However, we want to keep both versions of software available for future use (so not obsoleting either one of them). For compliance with IEC 62304, shall we start a new set of DHF? Will we need to perform the risk analysis again, or is there a way to justify that there will be no additional risk involved by this change? As we have a very tight timeline we would like to minimize the amount of documentation work to do. Does anyone have any suggestions? Thank you in advance for your help!!
