摘要

A balloon catheter comprising an elongate tube having a proximal end and a distal end, and a lumen therebetween, and a balloon at the distal end of the tube, in fluid, communication with the lumen. A magnetically responsive element at the distal end of the device sized and shaped to orient the distal end of the device in an operating region in a subject upon the application of a magnetic field from an external source magnet.
