摘要
A cardiac lead includes a half-domed, or semi-spherical shaped, or asymmetrical oval or circular distal assembly with or without an active fixation mechanism. The half-domed or semi-spherical or asymmetrical oval or circular shape provides directionality as to whether a flat side of the lead is facing the myocardial tissue and therefore the active fixation mechanism can be deployed safely into the myocardial tissue. Pacing/sensing electrodes may be constructed on the flat side of the lead to avoid the stimulation of the phrenic nerve.
