Abstract

A conveyor includes an inner core assembly and restraints. The restraint is rotatably arranged on the inner core assembly, and the restraint includes a fixed ring, a connecting rib and a clamping section in sequence from the proximal end to the distal end, and the two ends of the connecting rib are respectively connected with the fixing ring and the clamping segment, and the fixing ring Rotatably arranged on the inner core assembly, the clamping section has a contracted configuration and an expanded configuration. In the contracted configuration, the clamping section is used to clamp the proximal end of the blood flow guiding stent to the inner core assembly and the clamping section and the friction coefficient of the surface of the clamping section close to the inner core assembly is greater than the friction coefficient of the surface of the clamping section away from the inner core assembly. In the expanded configuration, the clamping section is separated from the blood flow guide bracket. The above-mentioned conveyer can avoid twisting and slipping of the blood flow guiding stent during the conveying process, has small pushing resistance, and is easy to load. The present application also provides a blood channel guiding stent system.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a transporter and a blood flow guide bracket system. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Intracranial aneurysms are mostly abnormal bulges that occur on the walls of intracranial arteries, and are the number one cause of subarachnoid hemorrhage. Subarachnoid hemorrhage is one of the main types of clinical hemorrhagic stroke. There are two main means of aneurysm treatment: surgical clipping and interventional therapy. Clinical trials have found that the mortality rate of aneurysm patients with interventional therapy is lower than surgical therapy. [0004] Blood flow steering stent is a new treatment method for intracranial aneurysms in recent years. Its principle is to reconstruct the correct path of blood vessels at the aneurysm and restore the direc...
