Abstract:
1. A medical device for delivering a magnetically responsive substance that is inserted within a subject body, the apparatus comprising: a tubular member having a proximal end, a distal end, and at least one magnetically responsive element disposed at the distal end of the tubular member; a coil disposed on the side of the tubular member and spaced proximally from the magnetically responsive element, where the coil is configured to generate a field that attracts and collects a magnetically responsive substance inserted within the body when a voltage is applied to the coil; a transducer disposed on a distal end portion of the medical device near the coil to generate ultrasonic vibration that disburses the magnetically responsive substance that was collected by the coil into the surrounding tissue when a high frequency alternating current voltage is applied to the transducer.
