  • MAGNETIC SYSTEM TO PREVENT MIGRATION OF INTRA-LUMINAL MEDICAL STENT AND METHOD THEREOF
    Publication number: 20190142539
    Abstract: Systems and methods for fixing a stent in position in an anatomical lumen. Such systems and methods include an intra-luminal stent and a magnet, implanted, for example, in the subcutaneous layer of the subject.
