Catheter- and visualization-based robotic surgery treats arrhythmia2011-04-05
A new form of robotic heart surgery that uses 3D medical visualizations as a guide has been implemented at the Rush University Medical Center in Chicago.

Called the Sensei robotic catheter system, the system involves a flexible robotic platform that guides catheters to hard-to-reach places in the heart using 3D medical animations as a guide.

It was approved for use in the U.S. after a clinical trial determined that the system is effective and safe in treating cardiac arrhythmias, according to the National Institutes of Health.

In catheter ablation, a small wire is inserted through an incision in a blood vessel in the leg and fed up to the hearts upper chambers, called the atria.

Once there, the catheter is then used to cauterize problematic nerves, which ultimately results in a restored heart rhythm if performed correctly.

The new surgery uses a mapping tool and a joystick-controlled maneuvering system to place the catheter more precisely. The mapping system, called EnSite, creates 3D medical animations of the interior of the atrium, allowing the operating area to be visualized without the use of fluoroscopy.
