Abstract
A catheter, formed in part of a polymer with a plurality of metal-coated nanotubes dispersed therein, is provided, along with methods of making and using such catheters. The method includes heating a polymer above a melting point of the polymer; dispersing a plurality of metal-coated nanotubes within the polymer; and forming the polymer having the plurality of metal-coated nanotubes dispersed therein into a catheter component. Methods of imaging a catheter including a polymer having a plurality of metal-coated nanotubes dispersed therein also is provided, which includes inserting a portion of a catheter into a body lumen; exposing the portion of the catheter to x-ray radiation; and obtaining an x-ray image of the portion of the catheter.
