Title: FLUORESCENT AND/OR NIR COATINGS FOR MEDICAL OBJECTS, OBJECT RECOVERY SYSTEMS AND METHODS
Abstract:
A composition for coating a medical device and a coated medical device are provided. The composition includes a polymeric matrix having non-toxic quantum dots or a fluorophore or both. The polymeric matrix contains the quantum dots or fluorphore and binds as a coating to the medical device. Coated medical devices can be readily identified within or outside of a body and in open or laparascopical surgeries, greatly reducing or eliminating the risk of a retained foreign object.
