DEPLOYABLE MULTI-ELECTRODE LEADLESS ELECTROSTIMULATOR

摘要

An intravascularly-deliverable electrode assembly can be used to provide electrostimulation. The electrode assembly can include an electrostimulation circuit located in a housing, two or more elongate members coupled to the housing and configured to anchor the housing to a heart, the two or more elongate members including two or more electrodes electrically coupled to the electrostimulation circuit and controllably addressable by the electrostimulation circuit for delivery of an electrostimulation to the heart. The two or more elongate members can be sized and shaped for intravascular delivery to the heart in a first configuration, and in response to a user actuation, the two or more elongate members can move to a second configuration that is expanded relative to the first configuration to securely anchor the intravascularly-deliverable electrode assembly to the heart. Circuitry within the electrode assembly can coordinate electrostimulation, such as for delivery to sites near each electrode.
