UK hospital performs endovascular surgery using robotic technology

St Mary's Hospital, part of the Imperial College Healthcare NHS Trust in the UK, has used Hansen Medical's Magellan robotic system for a fenestrated endograft procedure.

St Mary’s Hospital, part of the Imperial College Healthcare NHS Trust in the UK, has used Hansen Medical’s Magellan robotic system for a fenestrated endograft procedure.

The physicians used the new robotic system to deliver a stent through the endograft and into the patient’s renal artery. The Magellan robotic system is controlled from a workstation outside of the operating room. The system displays the patient’s blood vessels on a screen and allows the clinician to navigate through them with a flexible robotic catheter. The catheter can be steered by the clinician, who positions its moveable tip and joints to access the patient’s peripheral anatomy.

A patient undergoing endovascular robotic surgery will have a small incision in the groin, with minimal blood loss and a shorter hospital stay, according to Hansen. The company states that the robotic catheter can make the procedure more predictable, faster and with inproved technical accuracy and control.

Imperial College consultant vascular surgeon Nick Cheshire said that St Mary’s had pioneered the use of robotics in vascular surgery and worked with Hansen to develop the robotic system.

Hansen president and CEO Bruce Barclay said that the new Magellan robotic system was the first such system specifically designed for peripheral endovascular interventions. "It is designed to be flexible and versatile, allowing physicians to use it for complex catheter procedures," he added.

The Magellan robotic system is based upon the robotic technology incorporated in the Sensei-X robotic catheter system. It allows for independent, individual robotic control of the distal tips of both the outer sheath and the inner leader catheter, according to the company. The system is designed to allow for sufficient extension inside the body to better access hard-to-reach peripheral anatomy.
