Abstract: An adapter device that includes an adapter body having a first end and a second end. A connection interface is coupled to the first end, has a connection direction, and is configured to couple to a cardiac device. A receiving interface is disposed at the second end and has a receiving direction. The receiving interface includes a first receiving port that is in electrical communication with the connection interface and is configured to receive a first connector pin. A sealing member is configured to be sealably disposed over the receiving interface and configured to receive and frictionally engage at least a portion of the adapter body. In some embodiments, the connection direction and the receiving direction are the same. In some embodiments, the connection direction and the receiving direction are opposite.

Abstract: An example medical device includes a plurality of electrodes, therapy delivery circuitry, and processing circuitry configured to control the therapy delivery circuitry to deliver electrical stimulation to an intercostal nerve of a patient via at least two of the plurality of electrodes, wherein the electrical stimulation is delivered with stimulation parameters configured to suppress ventricular tachyarrhythmia of the patient, wherein the stimulation parameters comprise a stimulation frequency less than or equal to 40 hertz (Hz).
