BIO-METALLIC TUBE TYPE SUBSIDIARY STENT FOR THE TREATMENT OF PERIPHERAL NEUROVASCULAR ANEURYSM AND DELIVERY SYSTEM

摘要

PURPOSE: A bio-metallic tube type subsidiary stent for treating peripheral neurovascular aneurysm and a delivery system for the same are provided to ensure sufficient tension to the columnar direction and sufficient flexibility to the longitudinal direction. CONSTITUTION: A bio-metallic tube type subsidiary stent includes a plurality of link parts(10) and band parts(20). The link parts are expanded to the columnar direction of the stent and become curved to form wave shapes along the longitudinal direction of the stent. The band parts are arranged at the middle parts of adjacent link parts and are expandable to the columnar direction. The link parts are integrated with the band parts. The connecting parts of the link parts and the band parts are < or >-shaped.
