  • Patent number: 5665120
    Abstract: A biomedical material in use for curing the bone defect or the like in human being or an animal. The biomedical material is comprised of a flexible fiber-meshed micro-tube which has an outer diameter ranging from 50 .mu.m to 10 mm and is formed of a net or a cloth woven from fibers. The fibers are biodegradable and capable of maintaining their shape within a time period ranging from 1 week to 30 weeks in the body. Additionally, hydroxylapatite beads and/or flakes are filled in the fiber-meshed micro-tube. The biomedical material is located in the bone defect or the like under an operation, in which blood can effectively circulate through the mesh of the micro-tube and through the spaces among the hydroxylapatite beads and/or flakes, thereby promoting the cure of the bone defect or the like.
