Patent number: 10525170Abstract: Medical devices with a hydrogel layer covalently attached to a portion of the outer surface of the medical device are provided along with methods for applying the coating. The hydrogel layer can include a first polymer species comprising polyethylene glycol (PEG) and a second polymer species. Examples of the second polymer species include PEG and polyacrylamide (PAM). The first and second species can be at least partially cross-linked. Methods for forming the hydrogel coatings on the medical devices are provided including nucleophilic conjugate reactions, such as Click reactions.Type: GrantFiled: December 9, 2015Date of Patent: January 7, 2020Assignee: Tangible Science, LLCInventors: Karen Havenstrite, Victor W. McCray, Brandon M. Felkins, Paul Cook
