MICROBEADS FOR EMBOLIZATION AND COMPOSITION FOR TREATING PROLIFERATIVE DISEASES
The present disclosure provides a biocompatible polymer, and the polymer includes the embolic microbead including an iron adsorption block capable of adsorbing an iron component. The embolic microbead according to the an exemplary embodiment of the present disclosure adsorbs iron and thus effectively blocks an iron component delivered to cancer cells, and when used in embolization, it has an improved effect in treating cancers, such as liver cancer.
ANTISEPTIC WOUND DRESSING
The invention relates to an antiseptic material, in particular as a wound dressing, containing a carrier material and at least one antiseptic together with a surfactant, wherein the carrier material is equipped with a cyclodextrin or cyclodextrin derivative that is loaded in the antiseptic or antiseptics.
WOUND DRESSING ARTICLES MADE OF ARRAYS OF MICROSCOPIC NEEDLES OBTAINED FROM EXOSKELETONS OF CRUSTACEANS AND METHOD OF MANUFACTURING THE SAME
The present invention provides a novel and simple method for fabricating a layer (membrane) containing arrays of microscopic needles obtained from crab shells capable of effectively treating wounds and having other medical applications; the method comprises crustacean exoskeletons treated with a base solution, an acid solution, and then medicinally active ingredients such as polysaccharide, proterin, artificial polymer, and inorganic solution.
EXTRACELLULAR MATRIX SHEET STRUCTURES
An implantable medical product and method of use for substantially reducing or eliminating harsh biological responses associated with conventionally implanted medical devices, including inflammation, infection and thrombogenesis, when implanted in in a body of a warm blooded mammal. The bioremodelable pouch structure is configured and sized to receive, encase and retain an electrical medical device therein and to allow such device to be inserted into the internal region or cavity of the pouch structure; with the pouch structure formed from either: (a) first and second sheets, or (b) a single sheet having first and second sheet portions. After receiving the electrical device, the edges around the opening are closed by suturing or stapling. The medical device encased by the bioremodelable pouch structure effectively improves biological functions by promoting tissue regeneration, modulated healing of adjacent tissue or growth of new tissue when implanted in the body of the mammal.
