Aneurismal surgical device

Abstract

The invention discloses an aneurismal surgical device. The aneurismal surgical device comprises a scaffold, a delivering guide wire, a guiding sheath and a micro catheter, wherein the scaffold is a self-expanding scaffold; the delivering guide wire is arranged in the cavity of the guiding sheath, and the scaffold is bound outside the delivering guide wire; and the guiding sheath is connected with the micro catheter, and the cavity of the guiding sheath is communicated with the cavity of the micro catheter to form a channel for delivering the delivering guide wire and the scaffold to a human body. According to the aneurismal surgical device provided by the embodiment, the high-density and super-soft scaffold can be delivered to the vascular pathological change position and released, and the grid structure of the scaffold at the vascular pathological change position has high coverage rate, so that the scaffold released to the blood vessel plays the same role in parent artery healing, and vascular aneurysm can be better treated.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to an aneurysm operation device. Background technique [0002] Aneurysms are formed when the arterial wall is partially weakened due to disease, injury or congenital factors. Under the impact of blood flow, the weak point of the blood vessel wall protrudes outward and gradually expands. Aneurysms can occur in different parts of the body, most commonly abdominal aortic aneurysms and intracranial aneurysms. The goal of aneurysm treatment is to reduce the risk of aneurysm rupture, and the most fundamental method is to achieve the healing of the parent artery and the reconstruction of the anatomical structure of the arterial wall. [0003] At present, the endovascular interventional treatment of aneurysms mainly adopts the method of stent-assisted coils, that is, the stents with appropriate density are delivered into the diseased blood vessels, and then the coils are delivered ...

AI Technical Summary

Problems solved by technology

[0004] Since the terminal behavior of aneurysm packing treatment occurs in the aneurysm cavity, through the study of the prior art, the applicant found that the existing stent-assisted coil has a mass effect during the treatment of the aneurysm, and the aneurysm appears. Peripheral brain tissue, important blood vessels, and nerve compression symptoms, while the complete compact occlusion rate of coil packing is low, and the postoperative recurrence and recurrence rate are high

In addition, the head of the coil is very easy to pierce the thinner aneurysm wall, which will cause the aneurysm to rupture and directly lead to the death of the patient during or after the operation
