  • Publication number: 20180077929
    Abstract: The present invention is directed to methods and systems for reducing lipopolysaccharides on medical devices and fluids that are intended to be in contact with the human body or to be inside of the human body. In on embodiment, the present invention relates to methods for treating solutions containing one or more endotoxins at detectable levels by adding a suspension of a stearate, preferably calcium stearate, to said solution to reduce detectable amounts of said endotoxins; and optionally removing the stearate. The present invention is also directed to methods for treating medical devices and methods of treatment by contacting the devices or tissue surfaces of a mammal with a stearate suspension to reduce detectable amounts of endotoxins on said mammal.

  • Patent number: 9238088
    Abstract: An adhesion inhibiting surgical barrier. The surgical barrier includes a wound-facing polymeric coating comprising an enteric polymer; and at least one flexible substrate, the at least one flexible substrate having at least one exterior surface, wherein the polymeric coating is applied to the at least one flexible substrate to substantially cover the at least one exterior surface thereof. A method of inhibiting the formation of adhesions in a patient who has undergone a surgical procedure and a method of repairing a gastric or duodenal perforation are also described herein.

  • Patent number: 8991882
    Abstract: An engagement head for engaging a porous substrate includes at least two pin sets, each pin set including a plurality of pins arranged in a plurality of parallel pin rows at a predetermined pin angle, wherein pins of immediately neighboring pin rows are arranged such that pin angles for the pins in a pin row are inversely symmetrical to pin angles for the pins in a neighboring pin row. The pins of a pin row move collectively in the same direction when a pin set is extended, which direction is determined by the pin angle of the pin row, whereby neighboring pin rows move in opposite longitudinal directions from one another when the pin set is extended. The pin sets may be extended and retracted in unison by a single actuation source.
