Abstract
A granule or particle made of a chitosan material either carries within it a polymer mesh material of poly-4-hydroxy butyrate, or has interspersed with it a polymer mesh material of poly-4-hydroxy butyrate. The granule or particle can be carried within a polymer mesh socklet made of a material consisting essentially of poly-4-hydroxy butyrate. The granule or particle can be used to treat intracavity bleeding.
Claims4
A hemostatic agent comprising a granule or particle made of a chitosan material and a polymer mesh material consisting essentially of poly-4-hydroxy butyrate carried within the granule or particle.
An assembly comprising a hemostatic agent that takes the form of a granule or particle made of a chitosan material and strips of pieces of a polymer mesh material consisting essentially of poly-4-hydroxy butyrate interspersed with the hemostatic agent.
An assembly comprising a polymer mesh socklet made of a material consisting essentially of poly-4-hydroxy butyrate and a hemostatic agent that takes the form of a granule or particle made of chitosan material carried within the socklet.
