A novel remote-controlled robotic system for cerebrovascular intervention.

Area of Science:

• Medical Robotics
• Minimally Invasive Surgery
• Cerebrovascular Intervention

Background:

• Robotic systems offer advantages over conventional surgery in cerebrovascular intervention (CVI).
• This study presents a novel remote-controlled robotic system for CVI procedures.
• It includes the first in vivo proof-of-concept trial for this robotic system.

Purpose of the Study:

• To introduce and evaluate a remote-controlled robotic system for cerebrovascular intervention.
• To conduct the first in vivo proof-of-concept trial of the robotic system.
• To assess the feasibility of robotic guidewire navigation in a large animal model.

Main Methods:

• A master-slave control strategy was employed for the robotic system.
• The Omega 3 manipulator served as the master control.
• The slave side performed guidewire and balloon catheter insertion, and angiography in a pig model.

Main Results:

• The robotic system successfully inserted the guidewire and balloon catheter without vascular rupture.
• Angiography was successfully performed using the robotic system.
• The guidewire was precisely navigated into secondary branches of the pig's carotid artery.

Conclusions:

• The first in vivo trial confirms the feasibility and effectiveness of the remote-controlled robotic system.
• This robotic approach shows promise for advancing cerebrovascular intervention techniques.
• Further development could enhance efficiency and patient outcomes in CVI.
