Title: Needle-carried, transthoracic, cannula-type cardiac resuscitation instrument

Abstract: A transthoracic, cannula-type cardiac resuscitation instrument for use in conjunction with a rigid catheter-like needle, and adapted for rapid penetration of and placement in the wall of a person's heart. The instrument includes an elongated flexible tube which permits free axial insertion and withdrawal of such a needle for the purpose of the needle acting, among other things, as a rigid penetration and carrying device for carrying the tube into proper position with respect to a heart. The proposed tube, adjacent its distal end (which penetrates a heart wall during use) carries a pair of axially spaced inflatable-deflatable balloons that are positioned on opposite sides of an exposed electrical conductor usable for supplying electrical pacing pulses to a heart. After placement of the tube, and withdrawal of a needle, the tube may be used for injection of medications into the heart.
