Abstract:
A cardioplegia occluder for delivering cardioplegia to the aorta during cardiopulmonary bypass, comprising:a substantially rigid cannula having a distal region comprised of a material of at least 90 Shore A with an outer surface, a distal end adapted to enter the aorta, a proximal end adapted to receive cardioplegia solution, a longitudinal center axis, a cardioplegia lumen which extends distally from said proximal end and terminates and communicates with an infusion port in said distal region for delivery of cardioplegia solution to the aorta; andan occluder mounted on the distal region of the cannula, said occluder expandable between a contracted condition and an expanded condition, having a longitudinal center axis, wherein the occluder, when contracted, is closely associated with the outer surface of the cannula, while the occluder expands upon activation to substantially occlude the aorta downstream of the infusion port,wherein, during use, said occluder isolates the ascending aorta from the peripheral vasculature without substantial migration of the occluder within the ascending aorta.
