Local cardiac motion control using applied signals and mechanical force

Abstract

Apparatus ( 18 ) for performing a medical procedure on a beating heart ( 20 ) includes a mechanical stabilization element ( 25 ), a surface ( 27 ) of which is adapted to be applied to a segment ( 24 ) of the heart to reduce motion of the segment. One or more electrodes ( 100 ) are fixed to the surface of the stabilization element, so as to contact the segment when the stabilization element is applied to the segment. Preferably, at least one of the one or more electrodes is adapted to apply electrical signals to the segment so as to further reduce motion thereof, while the heart continues to pump blood.

1 . Apparatus for use during performance of a surgical procedure on a segment of a beating heart, comprising a surgical tool, which comprises: 
 a mechanical stabilization element, a surface of which is adapted to be applied, during the surgical procedure, to the segment of the heart to reduce motion of the segment; and    one or more electrodes, fixed to the surface of the stabilization element, so as to contact the segment when the stabilization element is applied to the segment.
