1. An implantable lead electrode assembly, the assembly comprising:
- an electrode having a tissue contacting surface;
a riser coupled to the electrode and extending in a direction opposed to the tissue contacting surface;
a head coupled to the riser; and
a lead coupled to the electrode, wherein the lead is coupled to the electrode without coupling through the riser or head.

Abstract
Electrical cardiac therapy devices including electrode lead assemblies having appendages coupled to an electrode. The appendage may take the form of a riser and a head having various characteristics. A further embodiment may include a cover and/or other features coupling the electrode to the riser. A lead may be provided for electrical coupling to the electrode. The lead may couple to the electrode exclusive of the riser and head. An implantable housing containing electrical circuitry for using the electrode to stimulate cardiac activity is also illustrated.
