A subcutaneously implantable device includes a housing, a clip attached to a top side of the housing, and an electrode. The clip is configured 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 sense an electrical signal from the organ, the nerve, the first tissue, and/or the second tissue through the electrode； deliver electrical stimulation to the organ, the nerve, the first tissue, and/or the second tissue through the electrode； and/or deliver a signal to a drug pump to provide a targeted or systemic therapeutic drug to the organ, the nerve, the first tissue, and/or the second tissue.
