Patent number: 10485892Abstract: There is provided a method for reducing microbial load at a site on the skin of a subject. The method comprises applying a dressing over the site on the skin of the subject at which a medical procedure that involves breaching the skin is to be performed. As used in the method, the dressing comprises a self-adhesive silicone gel sheet comprising at least about 95 wt % silicone and up to about 5 wt % of particulates of an antimicrobial dispersed in the silicone. The dressing is applied with the silicone gel sheet contacting the skin of the subject and is left in place to allow the antimicrobial to diffuse onto the site.Type: GrantFiled: March 9, 2016Date of Patent: November 26, 2019Assignee: Covalon Technologies Inc.Inventors: John Richard Hands, Valerio Ditizio

Patent number: 8840927Abstract: The present invention is a method for the modification of the surfaces of polymeric materials with polymer coatings that may be subsequently treated to be lubricious and anti-microbial. The method comprises incubating a photo-initiator-coated polymeric material with an aqueous monomer that is capable of free radical polymerization and exposing the incubating polymeric material to UV light creating a modified surface on said polymeric material. The method may additionally comprise adding a silver component to the modified surface. The silver component may be provided as a silver salt coating or a silver salt contained within a hydrogel bonded to the acrylate modified polymeric material surface.Type: GrantFiled: February 26, 2002Date of Patent: September 23, 2014Assignee: Covalon Technologies Inc.Inventors: Valerio DiTizio, Frank DiCosmo
