  • Patent number: 10485892
    Abstract: 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.

  • Patent number: 8967077
    Abstract: A system and method for photo-grafting a coating polymer onto the surface of a medical device are provided. The system comprises a plurality of stations including a novel grafting station. The system and method of the invention are both time- and resource-efficient. The system includes several stations, each station including a dipping tank. The system allows for the automated, semi-automated, or manual dipping of medical devices into the dipping tanks in a specified order, as desired, wherein at least one of the stations is a grafting station for photo-grafting the coating polymer onto the surface of the medical device. The system is modular, which allows for modification of the process as required, depending on the needs of the user. The system may comprise stations for incorporating an antimicrobial agent into the coating, and/or for rendering the coating lubricious.

  • Patent number: 8920886
    Abstract: One aspect of the present disclosure can include a method for grafting a coating polymer onto a surface of a device. The method can include the following steps: a) submerging the device into a photoinitiator solution; b) without first drying the device, submerging the device into a polymerizable solution; c) bubbling an oxygen-scavenging gas through the polymerizable solution; d) applying a UV light to the device to activate the photoinitiator, thereby grafting the coating polymer onto the device; and e) drying the device.

  • Patent number: 8840927
    Abstract: 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.

  • Patent number: 8697112
    Abstract: A method for treating a surface with a therapeutic agent is disclosed. The method comprises precipitating a therapeutic agent from a hydrophilic polymeric base layer with which the therapeutic agent has been complexed, to form a layer comprising microparticles of the therapeutic agent on the hydrophilic polymeric base layer, the hydrophilic polymeric base layer being grafted to the surface. Devices comprising a surface having a hydrophilic polymeric base layer comprising a hydrophilic polymer grafted to the surface and a layer comprising microparticles of a therapeutic agent disposed on and complexed with the hydrophilic polymeric base layer are also disclosed.
