23 Jul Novel vascular substituent develops under X line
Abstract
The utility model belongs to the biomedical engineering field, concretely relates to novel vascular substituent develops under X line, vascular substituent include the polycaprolactone inlayer, tungsten powder granule middle level and polyurethane are outer, three layer construction zonulae occludens, outer lactone and the polyurethane film of gathering for the thickness that adopts the high -voltage electrospinning technique to make is even of polycaprolactone inlayer and polyurethane, the tungsten powder grained layer comprises the spherical pure tungsten powder granule of surperficial free from admixture. The utility model discloses artificial blood vessel has biological tissue compatibility good (including blood compatibility and histocompatibility ), mechanical properties is good and X line perspective is whole visual down, and its preparation method reliable and simple, material safety are nontoxic, replace the human sick hematal ideal artificial blood vessel of damage.
