Endoenteric balloon coil

A magnetic resonance imaging system comprising:

• a magnetic resonance imaging device;
• a catheter including a magnetic resonance coil that is coupled to the magnetic resonance imaging device, the catheter including
• a catheter shaft including a proximal end and a distal end;
• a flexible lumen supported on the distal end of the shaft, the flexible lumen configured to be expanded and contracted using a fluid introduced via the proximal end of the catheter shaft;
• and
• the magnetic resonance coil formed on an exterior surface of the flexible lumen;
• wherein the magnetic resonance imaging device includes a match and tune circuit that is disposed remotely from the magnetic resonance coil.

A method for magnetic resonance imaging of anatomical locations within a patient, the method comprising:

• inserting a catheter into the patient, the catheter including
• a flexible lumen supported on a distal end of the catheter that is configured to be expanded and contracted using a fluid introduced via a proximal end of the catheter,
• a magnetic resonance coil formed on an exterior surface of the flexible lumen, the flexible lumen being contracted during insertion;
• locating the catheter to a desired anatomical location within the patient;
• expanding the flexible lumen;
• and
• performing magnetic resonance imaging using a magnetic resonance imaging system.
