Device for being implanted in abnormal bulging position of arterial canal wall

Abstract

The invention belongs to the field of medical instruments and relates to a device for being implanted in the abnormal bulging position of an arterial canal wall. The device comprises a bag capable of being implanted in the abnormal bulging position of the arterial canal wall and bulging, when the bag bulges, the bag has 3D modeling anatomy three-dimensional morphological features conforming to the implanting position, and therefore blood cannot flow into the abnormal bulging position of the arterial canal wall from an arterial canal. According to the device, the blood cannot flow into the abnormal bulging position of the arterial canal wall from the arterial canal, blood flow smoothness in the tumor-carrying arterial canal is kept, blood flow smoothness of branch blood vessels of the arterial canal is kept, thus, the device can be used for treating the diseases such as intracranial aneurysms, visceral aneurysms, false aneurysms, aortic aneurysms, artery dissection and aortic dissection, and a new way for aortic disease interventional therapy is expected to be opened up.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to an implant device, in particular to a device implanted in an abnormally bulging part of an arterial wall. Background technique [0002] Abnormal bulges on the arterial wall that are common clinically include: intracranial aneurysm, visceral aneurysm, pseudoaneurysm, aortic aneurysm, arterial dissection, aortic dissection, etc. [0003] Intracranial aneurysms (also known as "brain aneurysms") are cerebral hemangioma-like protrusions due to abnormal dilation of local blood vessels. Clinically, intracranial aneurysms can be divided into small (diameter ≤ 10mm), large (diameter 11-24mm), and giant (diameter ≥ 25mm); according to their shape, they can be divided into: saccular aneurysm, Dissecting aneurysms and fusiform aneurysms. Usually, small aneurysms with a diameter of <10mm have an extremely low rupture rate of about 0.05%, and those with a diameter of 10-25mm have an average a...

AI Technical Summary

Problems solved by technology

Because minimally invasive, small incision or even puncture under local anesthesia can solve the problems of aortic aneurysm rupture and wall thrombus falling off, it is gradually accepted by people, and interventional surgery technology is becoming more and more mature. , but the problems of various types of internal leakage have not been well resolved

The main advantage is less trauma, but this method is limited if the aortic intimal rupture is far away from the branch vessels of the aortic arch and the branches of the distal viscera

Although the birth of new technologies such as chimneys, window openings, and branch brackets can temporarily solve this part of the difficult interlayer to a certain extent, there are disadvantages such as subsequent internal leakage, continuous tearing of the interlayer, difficulties in stent fabrication, positioning, and release, and many long-term complications. also very obvious
