title: Pressurized contrast delivery for coronary arteriography.
abstract: A system is described for eliminating negative pressure source of air bubbles within a closed-circuit arrangement for dye delivery in coronary angiography. Replacing the usual manual pressure created by an aspirating syringe, this system pressurizes the reservoir bottle by means of a cuffed bag, double-lumen, one-way piercing spike and a 0.2 micron filter.
