Imricor Medical Systems (IMR: $0.29) is pioneering MRI-guided cardiac ablation, rather than ablation procedures conducted using x-ray fluoroscopy imaging. It is the only company in the world that sells MRI-compatible consumable devices used for cardiac ablation.
Cardiac ablation is a minimally invasive procedure whereby electrical abnormalities in the heart, which cause abnormal heart rhythms, are corrected by heating or freezing cardiac tissue inside the heart via a catheter. The issue with using x-ray to help guide the procedures is that the heart is almost invisible to x-rays.
