The mechanical characteristics of most commercially available catheter devices are provided by metallic components such as metal braiding or pulling wires in deflectable devices which make them unsuitable for the MR environment. We have developed a deflectable catheter that utilizes Kevlar fiber instead to produce the same shaft support and torquability with a braided tubing and tension mechanism for tip deflection. This device could enable a wide range of MRI-guided cardiovascular interventions in difficult to reach anatomies.
