Abstract: A method for capturing small objects in a confined space such as an artery or duct in a body by bringing an elongated flexible body having a distally disposed operative head provided with a plurality of nanostructures into proximity with the object. When in proximity intermolecular forces are created between the nanostructures and the object that attract the object to the operative head. By application of high frequency electrical current the nanostructures act as electrical knives to cut away or cauterize an object.
