A slide fastener bioabsorbable stent is applied as a cardiovascular system stent or a lumen stent in the disease of cardiovascular or narrow lumen. The slide fastener bioabsorbable stent includes a snap fastener stent, an edge slide fastener stent, a middle slide fastener stent, and a double fastener stent. The slide fastener bioabsorbable stent has good degradability and biocompatibility, and is more suitably used as a pediatric vascular stent, with which no late-onset stent thromboses after implanted, and thus it is not necessary to long-term take antiplatelet drugs and the subsequent surgical operation may not be affected. Also, it has a strong support, and thus can be widely used as a cardiovascular system stent or a lumen stent in the disease of cardiovascular or narrow lumen. The slide fastener bioabsorbable stent has simple production and convenient drug carrying, which can be used as a carrier of medicine or gene treatment. The stent can be matched with a delivery system, hence the difficulty of the surgery operation is reduced. Many animal experiments show that slide fastener bioabsorbable stent has high success ratio when being used, and has apparent curative effect and good clinical application prospect. |
