1. A system, comprising:

  • an intravascularly-deliverable elongate actuator; and

    an intravascularly-deliverable leadless electrode assembly, comprising;

    an attachment mechanism configured to secure at least a portion of the leadless electrode assembly to a myocardium of a heart, the attachment mechanism including a sharp tip configured to penetrate into the myocardium of the heart;

    a detachment member configured to be mechanically engaged and mechanically disengaged from the elongate actuator in response to a user actuation of the elongate actuator;

    an electrostimulation generator circuit; and

    respective electrostimulation electrodes coupled to the electrostimulation generator circuit and configured to provide an electrostimulation to the myocardium of the heart;

    wherein the detachment member is configured to be releasably mechanically coupled to the intravascularly-deliverable elongate actuator using a cavity and engaging feature configured to fit at least in part in the cavity.
