  • Tissue adhesive suitable for spray application
    Patent number: 6251370
    Abstract: An adhesive for tissue capable of uniformly forming a high concentration of fibrin so as to provide a high closing effect is disclosed. The adhesive for tissue comprises a fibrinogen solution and a thrombin solution which solutions are separated from each other. The adhesive is to be mixed and spray coated together with a sterile gas and has a volume ratio of the fibrinogen solution to the thrombin solution of about 2:1 to 10:1. This adhesive is to be sprayed together with a sterile gas for the adhesion or closing of living tissue of a human being or animal.
    Type: Grant
    Filed: April 28, 1999

  • Applicator for applying a biocompatible adhesive
    Patent number: 5582596
    Abstract: An applicator for applying a biocompatible adhesive containing human or aal protein as a principal ingredient to a surgical site of living body includes a housing to which a sterile gas is supplied, a sterile-gas supply tube connected to the housing, two adjacent sterile-gas ejecting nozzles for ejecting the sterile gas in the same direction, two adapters to which respective nozzles of syringe barrels are connected, and a pair of solution tubes, each having one end connected to the adapter and the other end protruded outwardly from the sterile gas ejection nozzle through an interior of the housing. Respective solutions supplied from the syringes via the pair of barrel adapters are ejected from the outlets of the solution tubes. The sterile gas is ejected from two sterile-gas ejection nozzles in the same direction. Consequently, the solutions are sprayed and mixed by the sterile gas, and then applied to the surgical site.
