Commercially available guidewires for X-ray-guided interventions are built from metal wires, usually coated by a polymer jacket. In MRI the metal parts heat up and conduct electricity. This leads to injury to the patient and the physician. Therefore, conventional guidewires are MR unsafe and must not be used in MRI.
The MaRVis platform technology integrates maintenance of the positive material properties of conventional guidewires and concomittant elimination of their critical electrical features in MRI. This proprietary technology by de novo design of medical devices obviates the use of metal cores and provides for a high degree of flexibility in their mechanical and visualization properties.
