  • TUBE-CUT HELICAL FIXATION ANCHOR FOR ELECTROTHERAPY DEVICE
    Publication number: 20230023767
    Abstract: An implantable medical device is disclosed herein and can be in the form of an implantable medical lead or a leadless pulse generator. The implantable medical device includes a body, at least one electrode and a tube-cut helical fixation anchor. The body includes a distal end and a proximal end opposite the distal end. The at least one electrode is supported on the body. The tube-cut helical fixation anchor distally extends from the distal end. The tube-cut helical fixation anchor may be fixed or extendable/retractable relative to the distal end. The tube-cut helical fixation anchor may be a result of a manufacturing process comprising cutting the tube-cut helical fixation anchor from a thin-walled tubular body.
    Type: Application
