The invention offered for licensing and commercial development is in the field of Interventional Magnetic Resonance Imaging (“iMRI”). More specifically the invention discloses a guidewire for magnetic resonance imaging with a single channel design to reduce complexity and to provide conspicuous tip visibility under MRI. In the design of the present device, the guidewire body includes an antenna formed from a rod and a helical coil coupled together. The helical coil can have multiple windings without a gap between the windings. The rod passes through the windings of the helical coil and is coupled to the helical coil using a conductive joint positioned at an end of the rod and at an end of the helical coil. Insulation can be positioned between the rod and the windings of the helical coil. The configuration allows visibility of the antenna along the length of a rod, except where it enters the windings of the coil. Thus, the tip visibility is enhanced as being separated from the rod.
CRADA Opportunity: The National Heart, Lung, and Blood Institute is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize technology involving single channel MRI guidewires. Please contact Peg Koelble at
