Abstract

The invention provides a regional blood flow guiding device as well as a preparation method and a use method thereof, and mainly aims to insulate a wide-necked aneurysm and a parent artery blood vessel and ensure blood flow in a collateral vessel to be unblocked. The regional blood flow guiding device comprises a skeleton, a regional dense net area, end part connection ribs and developing markers. The preparation method comprises the steps of skeleton cutting, residue removing, heat treatment and formation, acid pickling, polishing, marker assembling, and dense net area producting. The use method comprises the following steps: pressing the regional blood flow guiding device into a transferring sheath, sending the transferring sheath to a diseased region, locating under X rays via the developing marker of the regional blood flow guiding device, and releasing the device, wherein the dense net area completely covers the aneurysmal neck part of the wide-necked aneurysm, and blood flow in the collateral vessel is prevented from being unblocked. Compared with the prior art, the problem that the conventional regional blood flow guiding device is easy to cause blockage of the collateral vessel is solved, and operation risk is reduced effectively.

Description

technical field [0001] The invention relates to a local blood flow guiding device and a method for preparing and using the same, and belongs to the technical field of blood flow guiding devices and methods for preparing and using the guiding device. Background technique [0002] Aneurysms are hemangioma-like protrusions due to abnormal changes in arterial local blood vessels. Most of the main symptoms are caused by subarachnoid hemorrhage caused by rupture of the aneurysm, and the mortality rate is very high. With the aging of the population in our country, more and more patients suffer from aneurysms. If there is no better treatment, the patients may be in danger at any time. [0003] The treatment of wide-necked aneurysms has always been a hot topic in the field of interventional therapy. Traditional treatment methods include coil embolization, balloon-assisted coil therapy, and stent-assisted coil therapy. Simple embolization of wide-necked aneurysms with coils has a hi...
