    摘要: A component for satisfactorily plugging a bone tunnel formed in surgery such as ACL reconstruction by regenerating bone in a space portion of the bone tunnel (e.g., a bone tunnel for an arthroscope), is provided in order to solve the problems in the conventional technologies. The plug component is made of a calcium phosphate-based material, comprises a porous part having a porosity of 50 to 85%, and has a cylindrical shape such that one of its bottom surfaces forms an angle of 30 to 60 degrees to its central axis.

    摘要: The present invention relates to a medical nonwoven fabric comprising gelable cellulose derivative short-cut fibers as prepared by the paper making process, a preparation method thereof, and an adhesion prevention barrier using the same. The present invention provides a single phase of medical nonwoven fabric comprising gelable cellulose derivative short-cut fibers, to induce capillary action of micropores formed between the fibers and thereby control the gelation time, and provides a composite nonwoven fabric formed by laminating a nonwoven fabric layer comprising a different kind of biodegradable polymer material not susceptible to gelation on the single-phase of medical nonwoven fabric comprising gelable cellulose derivative short-cut fibers, thereby improving dimensional stability and convenience of surgical procedure. The present invention further provides a dyed medical nonwoven fabric to improve visibility, allowing easiness of recognizing the placement or location of the medical nonwoven fabric. Further, the single-phase nonwoven fabric or the composite nonwoven fabric, which makes it possible to efficiently control the gelation time by way of capillary action of the micropores formed between the fiber in the nonwoven fabric, can also be used as an adhesion prevention barrier with improved convenience of surgical procedure and post-surgical adhesion, in contrast to the conventional knit or film type adhesion prevention barrier.

    摘要: Provided is a stent graft that has superior prevention of endoleakage due to being resistant to creasing, and has superior prevention of graft migration as a result of promoting cell infiltration into gaps among microfibers in a dispersed state and forming an integrated structure with the cells in the landing zone of the stent. The stent graft according to the present invention is a stent graft comprising a stent graft fabric that has microfiber bundles consisting essentially of microfilaments having a filament linear density of 0.5 dtex or less, and said microfiber bundles having a total linear density of 10 to 60 dtex/120 to 3000 filaments, for the warp and/or weft, and in which the porosity of the microfiber bundles is 30% to 95%, wherein said stent graft has said stent graft fabric being located in at least 1 cm range from the central end.

    摘要: A stent includes a plurality of cylindrical elements joined along a common longitudinal axis to form a tube. The cylindrical elements include struts joined by crowns. Hollow, drug-eluting elements are disposed between adjacent cylindrical elements and connect adjacent cylindrical elements to each other. A therapeutic substance fills the lumen of the drug-eluting elements, and openings in the walls of the drug-eluting elements allow elution of therapeutic substance from the lumen for treatment of a vessel.
