Abstract
The present specification describes a biocompatible hemostatic composition and a biocompatible tissue sealant, which when used in combination provides a safe and effective method of achieving hemostasis. The biocompatible composition and sealant may be applied either on a surface of the patient's body, or inside the body cavity. The combination may be used to control bleeding from external wounds and internal injuries, as well as to minimize bleeding during surgical procedures.
Claims17
A method of using a combination of a biocompatible modified starch hemostatic product and a biocompatible sealant gel to treat a bleeding wound within or on a mammal, comprising:
- applying a first amount of said biocompatible modified starch hemostatic product to said bleeding wound;
- waiting for a first period of time to permit the biocompatible modified starch hemostatic product to hydrate and adhere to the wound and form a first absorbent layer on the wound surface;
- and,
- applying a second amount of said biocompatible sealant gel to the bleeding wound, after formation of the first absorbent layer, wherein the biocompatible sealant gel comprises a material different from the biocompatible modified starch hemostatic product and is adapted to gelatinize in less than three minutes upon contact with the wound and to form a second sealing layer over the first absorbent layer and wherein said first amount and said second amount in combination are sufficient to cause at least one of:
- hemostasis in said bleeding wound, wound sealing in said wound, reducing exudation of said bleeding wound, promoting tissue healing of said wound, protecting a surface of said wound, and avoiding infection of said wound.
The method of 14, wherein the polymeric compound is at least one of N-butyl cyanoacrylate, polyethylene glycol/polyethylene oxide (PEG/PEO), polyvinyl acetate (PVA), and polyvinylpyrrolidone (PVP).
