The process, particularly useful in blood oxygenators, whereby a differential velocity between a fluid and a diffusing surface of hollow tubes by a rotating member such that the boundary layer is perturbed enhancing the coefficient of mass and thermal transfer. The differential velocity is achieved by rotating hollow tubes containing one fluid in a second fluid, or by apposing a rotating member to the surface of the stationary hollow tubes.

A method and apparatus to arrest or reverse heart damage from myocardial infarction by using a peripheral, femoral-femoral full bypass along with the venting of the left ventricle wherein the rate at which blood is drawn from the femoral vein and the rate at which the left ventricle is vented are related in a predetermined manner. The damaged area is treated with a cardioplegic solution; the blockage causing the heart attack is then removed by a thrombolytic solution or by angioplasty, while blood is prevented from entering the ventricle and from reactivating the heart from its at-rest condition. Normal blood flow is then restored, and the various catheters and bypass mechanisms removed. The system is also useful for peripheral cardiopulmonary bypass systems not involving the application of a cardioplegic solution. The catheters are specially designed for their function.

An arterial cannula is formed with an angled shoulder that limits the degree of insertion of cannula tip into an artery. The shoulder also forms a seal with the artery. Suture flaps are formed on the cannula to attach the cannula to the patient's skin. A stylet for the cannula has a stop on its exterior that prevents blood flow between the cannula and the stylet, and permits clamping of the cannula with the stylet partially withdrawn. A removable anti-backflow ring seals the cannula and provides a convenient initial movement limit for the stylet stop.
