    摘要: Disclosed herein, among other things, is a system for electrical stimulation of blood vessels. An embodiment of the system includes at least one electrode having electrical contact with a blood vessel. The embodiment also includes a stimulation circuit electrically connected to the electrode, the circuit adapted to provide stimulation to the vessel. The embodiment further includes a controller connected to the circuit, the controller adapted to select frequency and voltage parameters for the stimulation circuit to selectively affect vascular therapy, including constriction of the vessel and dilation of the vessel. According to various embodiments, the stimulation circuit and controller are contained within an implantable medical device (IMD). The system also includes a sensor connected to the controller, and the controller initiates and adjusts therapy based on a signal received from the sensor, in varying embodiments.

    摘要: A method and apparatus for linear stimulation of the heart to resynchronize contraction for improved hemodynamic benefit. Linear stimulation may be accomplished using a linear source, which may comprise an elongated electrode or plurality of electrodes arranged so as to linearly stimulate the heart. A linear source may be coupled to the left ventricle, and one or more additional electrodes may be positioned so as to stimulate a separate region of the left ventricle or one or more additional chambers of the heart as well. Application of an electrical stimulus by the linear source may function to stimulate a larger region of the heart, thereby enhancing the resynchronization effect as well as providing other hemodynamic benefits.
