Snap-spin lead assembly and method therefor

摘要

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.
