ABSTRACT:
A sleeve or collar for preventing the migration of infection along the length of an implanted lead. The sleeve or collar is given anti-microbial properties, as by embedding therein or coating with anti-microbial substance. At the time that a changeable portion of an implantable device is changed-out, e.g., when the pulse generator in a pacemaker system must be replaced due to battery depletion, the collar or sleeve in accordance with the present invention is affixed to the lead and slid as far distal along the lead as possible, in order to ensure that a barrier is established to prevent the migration of infection to the extreme distal end of the lead. In one embodiment of the invention, the collar or sleeve can serve the dual purposes of establishing an infection barrier and of facilitating the anchoring of the lead in place.
