The clip is configured to anchor the device to a muscle, a bone, and/or a first tissue. The prong has a base portion attached to the housing, an arm portion extending from the base portion so as to define a first plane that includes opposite ends of the arm portion of the prong and is perpendicular to a horizontal plane of the housing, and a contact portion that is configured to contact an organ, a nerve, the first tissue, and/or a second tissue. The contact portion is angled away from the first plane. The electrode is at the contact portion of the prong. The electrode is configured to contact the organ, the 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. ## Claims ### Claim 1 A subcutaneously implantable device comprising: a housing; a clip attached to the housing that is configured to anchor the device to a muscle, a bone, and/or a first tissue; a prong having a base portion attached to the housing, an arm portion extending from the base portion so as to define a first plane that includes opposite ends of the arm portion of the prong and is perpendicular to a horizontal plane of the housing, and a contact portion that is configured to contact an organ, a nerve, the first tissue, and/or a second tissue, the contact portion being angled away from the first plane; an electrode at the contact portion of the prong, the electrode being configured to contact the organ, the nerve, the first tissue, and/or the second tissue; and circuitry in the housing in electrical communication with the electrode that 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. ### Claim 2 (depends on 1) The device of claim 1, wherein the clip is configured to attach the device to a xiphoid process and/or a sternum of the patient. ### Claim 3 (depends on 1) The device of claim 1, wherein the contact portion is angled away from a bottom of the housing. ### Claim 4 (depends on 3) The device of claim 3, wherein the contact portion is angled away from a side of the housing. ### Claim 5 (depends on 1) The device of claim 1, wherein the arm portion is a predominantly straight portion that is angled away from a bottom of the housing. ### Claim 6 (depends on 5) The device of claim 5, wherein the contact portion is angled away from a bottom of the housing and from a side of the housing. ### Claim 7 (depends on 1) The device of claim 1, wherein the prong further comprises: a sleeve extending along the base portion, the arm portion, and a portion of the contact portion; a wire extending through the sleeve, an end of the wire being connected to the electrode; and structural tubes extending through the sleeve along the base portion and the arm portion of the prong on opposite sides of the wire. ### Claim 8 (depends on 7) The device of claim 7, wherein the sleeve has a rectangular cross-section. ### Claim 9 (depends on 7) The device of claim 7, wherein the structural tubes have the same diameters as the wire or smaller diameters than the wire. ### Claim 10 (depends on 7) The device of claim 7, wherein the structural tubes are made of one or more of metal, polyurethane, silicone, and plastic. ### Claim 11 (depends on 7) The device of claim 7, wherein the structural tubes are solid. ### Claim 12 (depends on 7) The device of claim 7, wherein the structural tubes are hollow. ### Claim 13 (depends on 7) The device of claim 7, wherein the prong comprises two structural tubes. ### Claim 14 (depends on 1) The device of claim 1, wherein the contact portion is configured to be angled away from the housing toward the organ, the nerve, the first tissue, and/or the second tissue. ### Claim 15 (depends on 1) The device of claim 1, wherein the contact portion is angled away from the housing such that the prong is configured to push down against the organ, the nerve, the first tissue, and/or the second tissue. ### Claim 16 (depends on 15) The device of claim 15, wherein the prong is angled to apply pressure to the heart and is configured to bury into the cardiac tissue. ### Claim 17 (depends on 1) The device of claim 1, wherein the prong is attached to the housing via a housing latch. ### Claim 18 (depends on 17) The device of claim 17, wherein the housing latch is attached to a bottom of the housing and a pivot point of the prong is at the housing latch. ### Claim 19 (depends on 1) The device of claim 1, wherein the electrode has a conical shape, a spherical shape, a cylindrical shape, or a hammerhead shape. ### Claim 20 (depends on 1) The device of claim 1, wherein the prong comprises a spine made of shape-memory material.
