FIXATION DEVICE FOR CORONARY VENOUS LEAD

摘要

In one embodiment, the present invention provides a cardiac lead device (14) including a fixation mechanism (34) slidably attached to the lead such that when the fixation mechanism is expanded into contact with a body lumen, the lead may be moved relative to the fixation mechanism if desired. Such lead movement may be limited by complimentary structure on the lead body and the fixation mechanism that prevents the lead from moving unless sufficient force is applied to the lead.
