ABSTRACT:
A system and method are provided for attracting a magnetically responsive substance inserted in a subject's body towards a target area within the body to treat the area. The system generally comprises a medical device having a proximal end, a distal end, and at least one magnetic element disposed at the distal end of the medical device for orienting the distal end in a desired direction to place an aperture against the opposite wall of the vessel. The system further includes a voltage that may be applied to a coil that is disposed on the side of the medical device and proximally spaced from the magnetic element. A voltage is applied to the coil to attract the magnetically responsive substances inserted into the body around the coil. A high frequency alternating current voltage is applied to an adjacent transducer to ultrasonically disperse the collected magnetically responsive substances into the surrounding target tissue.
