Abstract:
1. An apparatus for detection and treatment of atrial arrhythmia, the apparatus comprising: an electrical lead having a proximal and distal portion, the distal portion being positionable in an atrial chamber of a heart, the proximal portion having an end configured to be coupled to a pacemaker device, the lead comprising a plurality of conductive wires; a plurality of membrane patches distributed along the electrical lead, each membrane patch configured to be attached to a wall of the heart and to bend and flex with motion of the heart without impeding motion of the heart; and a plurality of pairs of electrodes, wherein at least one pair of electrodes is positioned on each membrane patch, the electrodes of each pair being (i) coupled to a conductive wire of the lead, and (ii) configured to at least sense an electrical signal of the wall of the heart; and wherein the distribution of the plurality of membrane patches and electrode pairs along the lead is configured to allow the plurality of electrode pairs to be distributed in a pattern on the heart wall, the pattern defining an area for i) detecting a location of a foci of aberrant electrical activity located within or adjacent to the area, and ii) sending a pacing signal to that location to prevent or stop an occurrence of atrial fibrillation caused by that foci.
