Abstract

The invention relates to a blood flow control device, comprising a blood vessel stent and a filling capsule, wherein the blood vessel stent is hollow tubular, the filling capsule is arranged on an inner side wall of the blood vessel stent, and the filling capsule is provided with an accommodating space available for allowing a filling medium to be injected. The blood flow control device can be used as an auxiliary device for the treatment of a blood flow guiding device for a complex intracranial aneurysm. After the blood flow control device is placed in a blood vessel, the filling medium is injected into the accommodating space of the filling capsule, and the filling capsule is deformed and expanded, so that the diameter of the blood vessel is narrowed, and the blood inflow of the corresponding blood vessel is reduced, thereby avoiding the injection of high blood flow after the blood flow guiding device is placed into the tumor-bearing artery, and reducing the risk of bleeding.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a blood flow control device. Background technique [0002] The treatment of complex intracranial aneurysms has always been a difficult problem for neurosurgeons. Whether it is microsurgery or endovascular interventional therapy, there are problems such as high recurrence rate, difficult treatment, high surgical risk, and high probability of complications. In recent years, blood flow steering devices have brought hope to the treatment of some complex intracranial aneurysms, but there is also a high risk of postoperative bleeding, and unruptured aneurysms also have the possibility of bleeding after blood flow steering is placed, and once Bleeding, often life-threatening. [0003] Intracranial complex aneurysms implanted with blood flow diversion devices usually result from injection of high blood flow or self-melting of the aneurysm wall. In traditional treatment, the only way t...
