Abstract: A method and apparatus for carrying out aortic occlusion along with oxygen carrying fluid infusion for use during CPR including the use of a specially constructed balloon catheter which, when inflated, occludes the aorta such that an oxygenated fluid infused through the catheter will be restricted to that part of the aorta above the balloon occlusion. The inner lumen of the catheter must have a diameter of at least two millimeters.

Abstract: A no stick syringe is formed of a barrel having internal right hand threads at each end, a plunger which supports a piston near one end, and a tapered distal end provided with a left hand thread, and a needle having a cap with an internal left hand threaded and a flange configured to engage the internal threads of the barrel. The needle is connected to the tapered end of the plunger and the needle and plunger are threaded through the top internal threads of the barrel by rotating the plunger in the counterclockwise direction. At the base of the barrel the plunger is rotated clockwise to engage a needle flange with the bottom internal threads in the barrel to form a tight seal with a barrel opening and to subsequently disengage the plunger from the needle. After the syringe is used, the plunger is reconnected with the needle and released from the bottom internal by counterclockwise rotation of the plunger.
