ABSTRACT:
A pacing lead is disclosed having folded tine elements in a first normal state, the tine elements being adapted to be unfolded by insertion of a stylet. In the second unfolded state, the tine elements are stretched to conform closely to the outer diameter of the lead casing, providing a reduced cross-section that facilitates introduction of the lead, and repositioning of the lead tip. A telescoping arrangement of inner and outer tubing elements is used to enable the stretching of the tine elements.
