Linear stimulation of the heart for improved hemodynamic benefit

Abstract

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.

1 . A method for resynchronization of a heart comprising the steps of: 
 (a) coupling a linear source to a cardiac rhythm management device via a lead;    (b) coupling the linear source to a surface of the heart; and    (c) resynchronizing a contraction of the heart through linear excitation of the surface by the linear source.
