ALTERNATING CIRCUMFERENTIAL BRIDGE STENT DESIGN AND METHODS FOR USE THEREOF |
摘要 |
A stent includes a first section and a second section. The first section and the second section each include a plurality of expandable modules and a plurality of bridging modules. Each expandable module includes a plurality of strut elements that join together at a plurality of apices, and each bridging module includes bridging elements that connect an apex of a first module with an apex of a second module. In some aspects, the first section is more flexible along the longitudinal axis of the stent than the second section and is configured to be placed in a specific region of a vessel that requires flexibility to accommodate surrounding anatomy. In some aspects, the first section is more radially stiff than the second section and is configured to be placed in a specific region of the vessel that requires radial stiffness to counteract crushing force caused by surrounding anatomy. |
