Abstract

The invention discloses a support for treating intracranial aneurysms in an intervention therapy department. The support comprises a support body, a conveying device is movably connected on the inner side of the support body, the support body comprises a cobalt-base alloy foil ring, S-shaped holes are uniformly formed in the surface of the cobalt-base alloy foil ring in a chemical etching manner, and a nickel-titanium metal net ring is welded on one side of the cobalt-base alloy foil ring and is of a net structure woven by titanium alloy wires and nickel alloy wires. The support is of a structure with the cobalt-base alloy foil ring and the nickel-titanium metal net ring, the pure support is implanted, hemodynamics of the intracranial aneurysms is changed, thrombogenesis and organization in the aneurysms are facilitated, so that parent arteries are rebuilt from an anatomy, integration of the structure and inner walls of blood vessels are high, repulsion does not easily generate, the conveying device is arranged, conveying stability of support in the operation process is improved, operation efficiency is improved, and operation risks are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent for interventional treatment of intracranial aneurysms. Background technique [0002] At present, the treatment methods for intracranial aneurysms mainly include craniotomy to clamp the aneurysm neck and endovascular interventional therapy. [0003] Craniotomy to clamp the aneurysm neck is difficult and causes great trauma to the patient. Compared with surgery, endovascular interventional treatment is less difficult and causes less trauma to patients. At present, the overall prognosis of endovascular interventional treatment of intracranial aneurysms is better than that of craniotomy. Endovascular interventional treatment of intracranial aneurysms has gradually become the first choice for the treatment of intracranial aneurysms, and the treatment of various types of intracranial aneurysms with covered stents (especially intracranial giant, wide-necked aneurysms, ...
