ABSTRACT:
Electrode apparatus which is used with stimulation devices such as cardiac pacemakers or the like, and which has tissue-engaging members that are selectively retractable from tissue engagement without tearing or otherwise damaging the tissue. One or more tissue-engaging members is retractably mounted within the electrode body. Retraction or extension of the tissue-engaging member is accomplished with an elongated tool which is extendable through the hollow coil that attaches to the body of the electrode apparatus. In one embodiment of the electrode apparatus, the tissue-engaging members are non-rotatably extended and retracted from the apparatus, thereby further minimizing the possibility of damage to body tissue.
