Hi, Sumit, I am a final year science student from Ireland, as one of my final project in my medical device innovation course, i am required to build a minimum invasive device to remove the foreign bodies from Throat . At this stage, I ve built some concepts, I need to build a testing environment to prove my concept should work, my question is if you know what are the normally diameter of the camera in endoscopy? how much does it cost for normal endoscopy in the market? I would be really appreciate if you could answer my questions, thanks
