US-based Centerline Biomedical has reported a positive outcome from its two additional preclinical studies testing its advanced surgical navigation system, the Intra-Operative Positioning System (IOPS) for endovascular surgery.

The Cleveland Clinic developed IOPS uses a 3D model of the patient’s vascular system to locate instruments, such as catheters, with precision and without the requirement of being exposed to cancer-causing ionising radiation while reducing procedure times, complication rates, and overall costs.

The studies were headed by Cleveland Clinic surgeon Dr Matthew Eagleton along with University of North Carolina Aortic Center director Dr Mark Farber and Inova Fairfax Hospital in Virginia Chief of Vascular Surgery Dr Dipankar Mukherjee.

Commenting on the ease of use of the system Farber said: "This is great.

"We navigated to all four target vessels without any fluoroscopy.

“This is a realistic representation of anatomy and you can see real-time changes and movement of the catheter."

Results of the studies displayed the ability of IOPS to track navigation of catheters and guidewires with precision using an enhanced 3D visualisation avoiding any harmful affects generally posed by the conventional standard of care.

"This is a realistic representation of anatomy and you can see real-time changes and movement of the catheter."

Eagleton said: "This second round of work verified our ability to navigate the aorta and its branches, selecting the celiac artery, superior mesenteric artery, and renal arteries with the use of fluoroscopy limited to verification of catheter location.

“This technology will limit the need for extensive fluoroscopy units and provide more detailed anatomy that can be imaged while navigating through it.

“It will revolutionise vascular surgery."
