  • Snap-spin lead assembly and method therefor
    Patent number: 6842649
    Abstract: A lead assembly having a push-extendable active fixation mechanism. As the terminal end of the lead is pushed, the active fixation element extends from the lead body to a predetermined extension length. Optionally, a seal is formed at the distal end when the terminal is pushed and the terminal moves axially. A further option includes providing a snap fit connection with the terminal when the terminal end is pushed and the active fixation element is fully extended.
    Type: Grant
    Filed: December 14, 2001
    Date of Patent: January 11, 2005

  • Medical electrode assembly
    Patent number: 6704605
    Abstract: A medical lead for tissue stimulation and sensing is provided, the lead having an electrode with an active fixation mechanism. The active fixation mechanism using a conductive spring element or wave washer to maintain electrical contact after extension of the active fixation mechanism. The active fixation mechanism is engaged by rotating a piston within the electrode housing which advances the fixation mechanism distally.
