AI Technical Summary

Technical Problem

Existing IAAA repair techniques have gender, racial and ethnic differences, and EVAR, OSR and RAS techniques each have their own shortcomings, including endoleak, stent graft migration, device failure, and high risk of aortic clamp control.

Method used

Using robot-assisted surgery, a occlusion catheter is inserted into the common femoral artery. The retroperitoneum is incised lateral to the aorta and medial to the gonadal vein using a robotic surgical system and camera. The small intestine is suspended, the inferior mesenteric artery is clamped, and the inferior mesenteric artery is incised. The artery is then pinned to the anterior and posterior walls of the aneurysm sac. Intravascular balloon decompression is used to achieve decompression and closure of the aneurysm sac, avoiding aortic clamp control and providing a minimally invasive IAAR solution.

Benefits of technology

It achieved more consistent outcomes, reduced the risk of endoleak, decreased the risk of aortic bleeding, improved the safety and success rate of the procedure, reduced monitoring costs, and provided more durable aneurysm sac isolation and tolerability.

Abstract

A robotic surgical method for repairing a subrenal aortic aneurysm having an aneurysm sac in an aorta of a patient includes introducing at least one arm of a robotic surgical system and a camera into a specified portal of the patient. A graft is then attached to the proximal wall of the aorta. The aneurysm balloon is decompressed by inflating the intravascular balloon and inducing flow in the arteriovenous circuit. The anterior and posterior walls of the aneurysm sac are stapled and the robotic incision is closed. A method for inserting a tube includes deploying an intimal umbrella, partially expanding an expandable graft, deploying an outer membrane umbrella, and fully inflating the expandable stent.
