  • Patent number: 10385291
    Abstract: A liquid surfactant composition can include a C9-C20 alkylbenzene sulfonate, a nonionic surfactant, and an anionic surfactant. The anionic surfactant can include a first alcohol ether sulfate (AES) surfactant and a second AES surfactant. The first AES surfactant can have a molecular formula of R1—O—(CH2—CH2—O)m—SO3M, wherein R1 represents a C10-C20 alkyl group, m represents a number from 6 to 8, and M represents a monovalent cation. The second AES surfactant can have a molecular formula of R2—O—(CH2—CH2—O)n—SO3M?, wherein R2 represents a C10-C20 alkyl group, n is 2 or 3, and M? represents a monovalent cation. The first AES surfactant and the second AES surfactant can be present in the liquid surfactant composition at a weight ratio to provide the liquid surfactant composition with a fresh viscosity from about 350 centipoise (cPS) to about 550 cps.

  • Patent number: 9127091
    Abstract: The invention includes a medical hydrogel made from polymerized polysaccharide macromers. The macromers are preferably polysaccharides decorated with polymerizable groups, for example, methacrylates. The macromers may also be made into polymers of at least two macromers polymerized together. These polymers are preferably multi-armed or high-molecular weight and used for medical uses, for example, making coatings on medical devices. Macromers of N-vinylpyrrolidone are also disclosed herein.

  • Patent number: 5456711
    Abstract: A warp knitted vascular patch material, made in specific widths, the selvedges of the material are specially finished on the knitting machine without the introduction of additional threads to give a strong edge which will not fray and give firm support for the sutures. The specially knitted edges enables small neat sutures to be made without the risk of pulling out. This prevents all the problems of fraying edges and bulky seams found when unsized material is cut to the required width. This patch material is designed specifically for arterial closure following a carotid endorectomy.

  • Patent number: 5383927
    Abstract: The present invention provides vascular prostheses free of any substance that counteracts an anticoagulant comprising a base material, the base material having inner and outer surfaces, wherein the outer surface has a layer of a material capable of reducing the porosity of said prosthesis to blood or body fluid and a coating of compounded heparin bound thereon, and the inner surface has a coating of compounded heparin bound thereon, the compounded heparin comprising heparin and a cationic surfactant. The present invention also provides a method for forming a vascular prosthesis. The vascular prostheses of the present invention exhibit low porosity at the time of implantation of the prosthesis thereby obviating the need for pre-clotting the prosthesis to avoid leakage or hemorrhaging of blood through the prosthesis.
