ABSTRACT:
One embodiment of the electrode assembly is mounted at the distal end of a pacing lead including a lead body and at least one electrical wire conductor in the lead body and comprises a tip electrode including a tip and a connection of the tip to the wire conductor, and a partial skirt coupled to the lead body adjacent the tip. The partial skirt extends part way around the lead body backwardly from the tip. The partial skirt is capable of engaging trabeculae in a heart chamber for maintaining the electrode assembly in place and yet allows the electrode assembly to be removed when desired by the application of sufficient tension to the pacing lead to cause the partial skirt to fold back over itself as the pacing lead is withdrawn.
