Abstract
A method of fabricating a radiopaque dissolvable covering for a member on an implantable lead, including the steps of mixing a radiopaque material with a solvent to form a paste, applying the paste to the member and allowing the paste to harden. The lead preferably is provided with a drug incorporated therein which is subject to degradation at high temperature, located adjacent to the member, and the applying step preferably takes place at about room temperature. The member to which the paste is applied may be an active fixation device such as a barb or a helix or may be a deployable member such as a tine or an electrode bearing member.
