  • cardiac lead with active fixation and biocompatible lubricant
    Patent number: 6259953
    Abstract: A cardiac stimulator lead is provided that includes a connector for connecting to a cardiac stimulator and an insulating sleeve that has a first end coupled to the connector and a second end. The second end has an opening therein. An electrode is positioned in the insulating sleeve and has a piercing member. The electrode is moveable axially from a retracted position to an extended position wherein the piercing member projects from the opening. A conductor wire is disposed in the sleeve and coupled between the connector and the electrode for transmitting electric signals between the cardiac stimulator and the electrode. A lubricant is provided inside the insulating sleeve for lubricating the movement of the electrode. The lubricant reduces the potential for sticking, particularly for silicone lead sleeves.
    Type: Grant
