Developing structure, stent, and thrombectomy system

Abstract

A radiopaque structure, a stent and a thrombectomy system are disclosed. The radiopaque structure includes: at least one protrusion each for securing, supporting and connecting a radiopaque sleeve (2); at least one radiopaque sleeve (2) disposed over the respective at least one protrusion; and at least one filler (3) filled in a gap between the radiopaque sleeve (2) and the protrusion. Compared with the prior art, the radiopaque mechanism can enhance fluoroscopic visibility of radiopaque dots disposed at a distal end of a laser-cut thrombectomy device and solves the problem that not all metal struts in the laser-cut thrombectomy device can be seen under fluoroscopic imaging. The radiopaque structure can be used in any types of stent and is not limited to being used in a thrombectomy device.
