A subcutaneously implantable device includes a housing, a clip attached to the housing, and an electrode. The clip is configured to move between an open position and a closed position to increase or decrease an opening between the housing and the clip to anchor the device to a muscle, a bone, and/or a first tissue. The electrode is configured to contact an organ, a nerve, the first tissue, and/or a second tissue. Circuitry in the housing is in electrical communication with the electrode and is configured to provide monitoring, therapeutic, and/or diagnostic capabilities with respect to the organ, the nerve, the first tissue, and/or the second tissue.
