Abstract
A medical electrical lead that includes an indicator member that acts as a visual aid in implanting an electrode into a body tissue while using a fluoroscope. In an example embodiment, a medical electrical lead assembly includes an electrode head member, an electrode and a shaft member, the shaft member being retractable and extendible within the electrode head member. Each of the electrode, electrode head member and shaft member have, respectively, a distal end and a proximal end, and the electrode head member has an outer surface. The medical lead assembly includes an indicator coil member disposed on the outer surface of the electrode head member that is spaced laterally away from the shaft member in a first retracted position. The shaft member moves in alignment with the indicator coil member in a second extended position to indicate that the electrode extends out from the electrode head member.
