"The successful curative treatment of many congenital malformations and acquired diseases of the heart requires an effective method for performing reparative surgery in the open heart under direct vision. The advent of controlled cross circulation as a successful method for totally by-passing the heart and lungs has demonstrated that intracardiac corrective surgery is both possible and feasible for certain of these congenital defects heretofore considered inoperable. This ability to carry out definitive reparative procedures inside the human heart under direct vision and at a reasonable risk has promised the early development of curative surgery for other congenital cardiac conditions as well as acquired diseases of the valves or coronary arteries which are not now curable by existing surgical techniques. The magnitude of these potential demands emphasizes the need for widely applicable techniques for maintenance of the patient's circulation during the by-pass interval. The essence of wide applicability is simplicity combined with effectiveness. The simple disposable artificial oxygenator herein described serves as a temporary replacement for the human lungs and appears to be a significant step forward in the fulfillment of these concepts of safety and wide applicability. This oxygenator has no moving parts, is assembled entirely from commercially available plastic tubing, and is sterilized by autoclaving." Lillehei, et al. Clarence Walton Lillehei (1918-1999), was an American surgeon who pioneered open-heart surgery, as well as numerous techniques, equipment and prostheses for cardiothoracic surgery.

"Clearly the surgeon's ultimate goal in treating the tetralogy of Fallot type of congenital heart defects should be to restore the circulation to normal. This is accomplished by both closing the ventricular septal defect and removing the pulmonary stenosis, whether valvular or infundibular. The advent of controlled cross circulation as a successful method for direct vision intracardiac surgery has made such corrective surgery possible. Since our initial experience in 1954 with the curative procedure for the tetralogy defects, we have come to adopt that plan for all patients with this lesion currently in need of surgical treatment."
