  • RF lead fixation and implantable lead
    Patent number: 5383922
    Abstract: A method and apparatus for affixing implantable catheters and leads to body tissue. An electrode located on the lead or catheter is coupled to an RF signal generator, of the type employed to perform electrosurgical procedures such as electrocoagulation. The RF signal causes the electrode to adhere to body tissue, thus stabilizing the location of the catheter or lead. The electrode may be an electrode normally employed for other purposes, such as cardiac pacing, or may be a dedicated electrode employed only for affixation. Contact between the electrode and the RF signal generator may be made by a conductor permanently mounted within the catheter or lead, or by a removable conductor.
