Stretchable waterproof composite material and a method for its use
10583045 · 2020-03-10 · ·

A waterproof composite material that comprises three layers, a top layer, a middle layer, and a bottom layer. The middle layer is made of foam while the top layer and bottom layer can be made from a variety of films. The top layer and the bottom layer are formed in a quilted pattern. The top layer and the bottom layer are bunched up (meaning there is extra material there allowing more stretch). A method of manufacturing the waterproof composite material includes placing the three layers on (or in), stretching the middle layer, and then applying a quilt (or other) pattern (using heat and/or pressure) which causes the quilted pattern on the top layer and the bottom layer. The natural contraction of the middle layer (which was stretched when the composite was formed) causes bunching of the top layer and the bottom layer.

Biomaterial Devices and Topical Compositions for Guided Tissue Regeneration

Devices for guided tissue regeneration (GTR) include a matrix of chitosan and mutable collagenous tissue (MCT) wherein the chitosan is electrostatically bonded to the MCT to form MCT-chitosan composite material. The MCT can be isolated from invertebrate marine organisms, such as sponges, jellyfish, mollusks and echinoderms. The MCT-chitosan composite material can be formulated as a biofilm, a 3D-sponge, a hydrogel, or as an electrospun nanofiber, or the MCT-chitosan composite material can coat a biomaterial surface. The devices can include wound dressings and tissue sponges, including 3D sponges. Applications include tissue engineering and wound healing, as well as burns and other related guided tissue regeneration applications. MCT and MCT-chitosan composite material, contained in a pharmaceutically acceptable topical carrier, also has cosmeceutical applications, for treating scars, as well as skin discoloration and various pigmentation issues, including melasma/chloasma.
