  • Medical device coating with a biocompatible layer
    Patent number: 11260150
    Abstract: 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: Grant
    Filed: December 24, 2019
    Date of Patent: March 1, 2022
    Assignee: Tangible Science, Inc.

  • Contact lens with a hydrophilic layer
    Patent number: 10451896
    Abstract: Embodiments of the technology relate to a contact lens having a core that is covalently coated by a hydrogel layer, and to methods of making such a lens. In one aspect, embodiments provide for a coated contact lens comprising a lens core comprising an outer surface; and a hydrogel layer covalently attached to at least a portion of the outer surface, the hydrogel layer adapted to contact an ophthalmic surface, wherein the hydrogel layer comprises a hydrophilic polymer population having a first PEG species and a second PEG species, the first PEG species being at least partially cross-linked to the second PEG species.
