Electrical cardiac therapy devices including lead electrode assemblies for implantation into a patient comprising an electrode having a first face and a second face, and an appendage extending opposite the second face of the electrode, the appendage including an eyelet for securing an insertion device thereto. The assembly may further include an electrode frame assembly to which the appendage may be attached. Alternatively, the appendage may be formed as part of a molded electrode frame assembly. A backing piece may be provided between the electrode frame assembly and the electrode. The frame assembly may cover a portion of a front side of the electrode. Further embodiments include an electrode lead assembly including an appendage with an eyelet and an electrode insertion tool adapted to engage the eyelet. Another embodiment is a treatment kit including an electrode lead assembly having an appendage with an eyelet, an electrode insertion tool adapted to engage the eyelet, and an implantable housing having circuitry for providing electrical cardiac therapy.
