  • Cardiac lead permitting easy extraction
    Publication number: 20020123785
    Abstract: An extractable lead and method for lead explantation is provided. The lead includes a distal element having a cavity. The cavity shaped to receive the distal end of a removal stylet. The cavity and the distal end configured to cooperate such that the distal end is secured within the cavity by rotation of the stylet. The method provides for removal of an implanted lead by securing a distal end of a removal stylet with a cavity by rotation and applying an extracting force to the lead through the removal stylet.
