ABSTRACT:
The electrode assembly is mounted at the distal end of a pacing lead comprising a lead body and at least one wire conductor in the lead body. The assembly comprises a tip electrode including a tip and a connection to the wire conductor and a skirt extending around the lead body and backwardly from the tip. The skirt has at least two slits extending axially therein from the rearward edge thereof to separate the skirt into at least two adjacent separated skirt sections. The skirt also can have one or more annularly and radially extending spurs which are adapted to engage trabeculae in a heart chamber for anchoring and maintaining the electrode assembly in place. The skirt sections allow and enhance removal of the electrode assembly when desired by the application of sufficient tension to the pacing lead to cause the skirt sections to fold back over themselves as the pacing lead is withdrawn from the body.
