Medical Composition Comprising Adipose Tissue-Derived Extracellular Matrix And Method For Preparing Same
The present invention relates to a medical composition and a method for preparing the same, the medical composition comprising: an adipose tissue-derived extracellular matrix powder; and a biocompatible polymer or a crosslinked product of the biocompatible polymer. The medical composition according to the present invention exists in a well-aggregated state even after implantation in the body and can maintain the volume thereof for a certain time.
AN ADHESIVE BODY DRESSING AND METHOD FOR MANUFACTURING AN ADHESIVE BODY DRESSING
An adhesive body dressing includes a hydrocolloid adhesive layer (H) and a backing layer (B) provided on a first side of the hydrocolloid adhesive layer (H). The backing layer (B) is made of biodegradable polymer material.
Anisotropic wound closure systems
Novel compositions and systems for closure of wounds are disclosed. The compositions provide devices of improved flexibility and elasticity and are readily applied to wound sites or over wound closure devices. The present invention is also directed to a novel platinum catalyst for use in such compositions. The catalyst provides for rapid curing on topical surfaces such as skin and bonds to such surfaces in about 2-5 minutes.

WOUND COVERINGS COMPRISING VITAMIN D AND RELATED METHODS
A wound covering is provided that comprises a substrate and vitamin D, or analogues or metabolites thereof, embedded in the substrate. Methods of making a wound covering are also provided and include the steps of providing a solution that includes a polymer; adding vitamin D, or analogues or metabolites thereof, to the solution to form a mixture; and forming one or more fibers from the mixture that are then embedded with the vitamin D, or analogues or metabolites thereof. Methods of treating a subject are further provided and include the step of applying a wound covering including one or more fibers embedded with vitamin D, or analogues or metabolites thereof, to a site on a subject.
ABSORBENT ARTICLE HAVING A LOTIONED TOPSHEET
The absorbent article of the invention has a liquid impervious backsheet and a liquid pervious topsheet joined to the backsheet. The topsheet has an inner surface oriented toward the interior of the absorbent article and an outer surface oriented toward the skin and hair of the wearer when the absorbent article is being worn and an absorbent core positioned between the topsheet and the backsheet. At least a portion of the topsheet outer surface comprises an effective amount of a lotion coating which is semi-solid or solid at 20 degrees C., the lotion coating comprising:
(i) from about 10 to about 95% of a substantially water free emollient having a plastic or fluid consistency at 20 degrees C. wherein the emollient contains 5% or less water, the emollient comprising a member selected from the group consisting of petroleum-based emollients, fatty acid ester emollients, alkyl ethoxylate emollients, and mixtures thereof;
(ii) from about 5 to about 90% of an agent capable of immobilizing the emollient on the outer surface of the topsheet, the immobilizing agent being miscible with the emollient, the immobilizing agent having a melting point of at least about 35 degrees C. wherein the immobilizing agent is selected from the group consisting of polyhydroxy fatty acid esters, polyhydroxy fatty acid amides, C14-C22 fatty alcohols, C14-C22 fatty acids, C14-C22 fatty alcohol ethoxylates with a degree of ethoxylation of 4 or less, and mixtures thereof.
COMPOSITION, APPARATUS, KIT AND METHOD AND USES THEREOF
A curable composition for use in wound care comprising, apportioned between at least one Part A and at least one Part B: one or more alkenyl-group containing polymers (i) having at least one alkenyl group or moiety per molecule, one or more SiH-containing polymers (ii) having at least one Si—H unit per molecule; and a catalyst (iii) for curing by addition of alkenyl-containing polymer (i) to SiH-containing polymer (ii), Part A and Part B independently having viscosity at 23° C. in the range 5-300 Pa.Math.s, preferably 10-100 Pa.Math.s, at a shearing rate of 10 s.sup.−1, and when combined in one Part having cure time at 23° C. in the range from 0.5 min to 25 min, wherein when dispensed into a location about a wound dressing, said wound dressing overlying a wound site and skin thereabout, said dispensing being so as to intimately contact and overlie an edge of said dressing and skin about said edge, the composition cures in contact with said edge and skin at 32° C. to an elastomer exhibiting zero or low tack at a time in the range from 0.5 to less than 30 minutes, apparatus for use with said composition comprising dispensing apparatus or wound dressing, a kit comprising the same, and methods of dispensing and curing the same and of using the same in sealing a wound dressing and in treating a wound site of a human in need thereof.
