Patent number: 10330442Abstract: A reversible camouflage material including a textile layer having a woodland camouflage print thereon, an infrared suppressing layer, and a textile layer having a desert camouflage print thereon is provided. The infrared suppressing layer may include a polyurethane layer sandwiched between a carbon-containing ePTFE layer and an ePTFE layer. The carbon may be provided in an oleophobic layer on the ePTFE or within the ePTFE film. In one embodiment, the desert camouflage textile is absent and a coating composition that includes a colorant and infrared suppressive additives is applied to the outer surface of the ePTFE layer. The inventive camouflage material demonstrates camouflage concealment in the near IR (nIR) and short wave infrared (SWIR) wavelengths of the electromagnetic spectrum. In addition, the camouflage material is highly breathable and lightweight. The material is particularly suitable for making reversible camouflage garments such as jackets and pants.Type: GrantFiled: July 7, 2016Date of Patent: June 25, 2019Assignee: W. L.

Patent number: 10329466Abstract: Adhesive compositions are provided that include a crosslinked silicone gel, a hydrophilic component dispersed in the silicone gel, and an antimicrobial agent dispersed in the silicone gel. The adhesive composition is readily applied to (and removed from) skin, and has desirable hydrophilic and antimicrobial properties. Advantageously, the hydrophilic component in the crosslinked silicone gel is not readily extractable (e.g., into a pH 7 buffer). Surprisingly, the combination of hydrophilic component with antimicrobial agent in the crosslinked silicone gel can provide a synergistic level of antimicrobial activity.Type: GrantFiled: March 13, 2013Date of Patent: June 25, 2019Assignee: 3M Innovative Properties CompanyInventors: Michael D.

Patent number: 10314683Abstract: Absorbable polyester fibers, braids, and surgical meshes with prolonged strength retention have been developed. These devices are preferably derived from biocompatible copolymers or homopolymers of 4-hydroxybutyrate. These devices provide a wider range of in vivo strength retention properties than are currently available, and could offer additional benefits such as anti-adhesion properties, reduced risks of infection or other post-operative problems resulting from absorption and eventual elimination of the device, and competitive cost. The devices may also be particularly suitable for use in pediatric populations where their absorption should not hinder growth, and provide in all patient populations wound healing with long-term mechanical stability. The devices may additionally be combined with autologous, allogenic and/or xenogenic tissues to provide implants with improved mechanical, biological and handling properties.Type: GrantFiled: July 21, 2016Date of Patent: June 11, 2019Assignee: Tepha, Inc.Inventors: David P.
