Embodiment 1

[0040] In situ laser arterial fenestration device including aortic stent graft: Valiant stent, zenith flex stent, Ankura thoracic aorta stent graft, "chimney" stent and laser are used to treat aortic aneurysm or aortic dissection disease ; The laser is applied to the aortic stent graft corresponding to the branch vessel.

[0041] Using the characteristics of laser technology, after the aortic stent graft is released, laser is used to open the window on the aortic stent graft corresponding to the branch blood vessel according to the patient’s blood vessel condition, and the stent graft is implanted or Bare stents to reconstruct the blood flow of branch vessels, reduce and reduce the occurrence of related complications;

[0042] Preoperative evaluation All patients were evaluated for medical history and complications before surgery. At the same time, aortic CT angiography (computed tomography angiography, CTA) was performed, and 64-slice CT (scanning thickness 0.6mm) was used to scan...

Abstract

The invention belongs to the technical field of cross of medicine and engineering and relates to an in-situ laser pulse artery opening device and application thereof. The in-situ laser pulse artery opening device comprises aorta covered stents including the Valiant stent, the zenith flex stent, the Ankura chest aorta covered stent and the chimney stent and a laser. According to the in-situ laser pulse artery opening device, after the aorta covered stents are released, according to the blood vessel condition, the aorta covered stents corresponding to branch blood vessels can be opened through the laser, and the covered stents or bare stents are planted into the opened branch blood vessels to rebuild blood flows of the branch blood vessels and reduce occurrence of relevant complications. According to the in-situ laser pulse artery opening device, the covered stents of standard specifications are adopted, no anatomical structure is destroyed, a stent system does not need to be customized independently according to the individual special anatomical form, and the in-situ laser pulse artery opening device can be used for treating aortic aneurysm or aortic dissection diseases.

Description

Technical field [0001] The invention belongs to the technical field of the intersection of medicine and engineering, and relates to an in-situ laser arterial fenestration device and its use. The in-situ laser arterial fenestration device of the present invention, after the aortic stent graft is released, can use laser to open the window on the aortic stent graft corresponding to the branch blood vessel according to the blood vessel condition, and implant the fenestrated branch blood vessel Into the covered stent or bare stent to rebuild the blood flow of the branch vessels, reduce and reduce the occurrence of related complications. The in-situ laser arterial fenestration device of the present invention can be applied to treat aortic aneurysms or aortic dissection diseases. Background technique [0002] Data show that aortic aneurysms and aortic dissections are life-threatening diseases; among them, pathological expansion of the aorta exceeds 50% of the normal vessel diameter, wh...
