Abstract
A new device has been developed to provide complete de-airing of the heart after cardiopulmonary bypass. The apparatus consists of a special aspiration needle threaded to the bottom of a transparent bulb. A 1-way flutter valve is mounted at the top of the bulb, which creates a vacuum when the bulb is squeezed. This device has been used in 4 adults and 2 children, for both congenital and acquired heart disease. Preliminary results have shown that this device's active suctioning of air results in effective removal of air from the cardiac chambers; the transparent bulb enables the surgeon to visually determine that the de-airing procedure is complete.
