Patent Issued for Compositions I-I and products and uses thereof (USPTO 11938231).

Smith & Nephew PLC has been issued a patent for a curable composition used in wound therapy, specifically in negative pressure wound therapy (NPWT). The composition can be shaped to fit the wound and is sterilizable, making it suitable for medical use. The patent also discusses the challenges of sterilizing the composition and the need for packaging that can withstand the required heat sterilization process. The composition consists of two parts that are sealed separately to prevent contamination and forms a porous foam when combined. The method of preparing the composition involves heating the sealed parts at an elevated temperature for a specific period of time. The composition is sterilized using dry heat sterilization and is packaged in receptacles that are resistant to steam penetration. The patent provides additional details about the materials used in the composition and the curing process. [Extracted from the article]
