ABSTRACT:
A medical instrument includes a catheter having a distal end insertable within a body lumen and having longitudinally spaced apart and circumferentially-protruding first and second pods. The first pod has a first exterior surface with a first surface portion. The first surface portion includes an energizable first electrode pair of circumferentially-spaced-apart electrodes. The first surface portion has a shape adapted to advance the first pod within the lumen upon contraction of muscular lumen tissue contacting an energized first electrode pair. The second pod has a second exterior surface with a second surface portion. The second surface portion includes an energizable second electrode pair of circumferentially-spaced-apart electrodes. The second surface portion has a shape adapted to advance the second pod within the lumen upon contraction of muscular lumen tissue contacting an energized second electrode pair. A method for using a medical catheter is described wherein each pod includes an inflatable balloon.
