Class II medical devices generally refer to devices that are used directly on the human body, such as various surgical instruments, monitoring equipment, etc., whereas fluorescents are more commonly used in drug discovery and development, drug imaging, and biological laboratories.
However, in some specific cases, fluorescent agents may be used to assist or improve the use of Class II medical devices. For example, a fluorescent agent may be used in some surgeries to help physicians better visualize the location or structure of organs or blood vessels. In this case, the fluorescent agent as an adjuvant would be used in conjunction with a Class II medical device.
