Pericardial MRI undergoes scrutiny

Columbia Heights, MN-based Comedicus is developing a product that could allow MR scanners to image the heart from inside the pericardial sac. The company's intrapericardial MRI device is designed to provide images of coronary artery walls and a 360º view of the heart, as well as provide a pathway for simultaneous therapy. Current cardiac MRI technology involves accessing the area behind or near the heart by inserting a coil down the esophagus or up through the femoral artery. Comedicus has taken a slightly different approach, developing the means to insert an MRI coil into the pericardium so that the coil can be looped around the heart. The insertion technology is in hand. The company is currently working with the University of Minnesota to develop a working prototype of the MRI coil. Animal tests could be completed by May 2002.
