Hansen Medical, Inc. has announced that for the first time ever surgeons at St. Mary's Hospital, part of the Imperial College Healthcare NHS Trust, in London, UK, used the company's Magellan Robotic System to treat a patient with a complex abdominal aortic aneurysm.
"This new technology means a broader group of patients might now be operated on," said Professor Nick Cheshire, consultant vascular surgeon and head of circulation and renal sciences at Imperial College Healthcare. In this specific procedure the physicians used Magellan to deliver a stent through the endograft and into the patient's renal artery. "The real trick here is to drive into the blood vessel though the stent endograft, and then out through the specially formed window into the kidney vessel," stated Cheshire. "On the right side using conventional manual technique, it took us about ... an hour and twenty minutes. On the left side of this patient, when we used the robot, it took us about twenty minutes."
The new robotic system is controlled from a workstation outside of the OR. It displays the patient's blood vessels on a screen and allows the clinician to navigate through them with a flexible robotic catheter. The clinician can steer the catheter and position its moveable tip and joints to access the patient's peripheral anatomy. Consultant interventional radiologist Dr. Mo Hamady, who operated the robot, said, "This technology means you have control during complex procedures. Whereas surgeons would normally feed the catheter into the patient's body by hand, the robot gives you precision so there is the potential for less risk of damage to the wall of the patient's blood vessels."
