Anatomical Model, Life-Size Heart Model with Bypass

Two hearts in one, our life size heart has been fitted with detachable / re-attachable bypass vessels for demonstrating single, double, and triple bypass grafts as well as a normal heart without bypasses. This resilient vinyl heart divides into anterior and posterior sections to access its pumping chambers and valves. Vessels are color-coded red or blue to indicate whether they carry oxygenated or deoxygenated blood. Significant cardiac features, 33 in all, are hand numbered on the model for identification in the accompanying key.
Nesting on a form-fitting display base, the heart lifts off for hands-on observation and study. Overall dimensions: 4x4x6 inches (11x11x15cm).

Key to Life-size Heart Model
The tubing on this model represents segments of the saphenous vein of the leg, surgically anastomosed to provide bypass vessels between the Ascending Aorta (#24), and the following coronary arteries.
Right coronary artery (#8)
Left anterior descending coronary artery (#11) Circumflex branch of the left coronary artery (#3)
The tubes are removable to allow the demonstration of single or double bypass procedures, or to allow use of the model as a “normal” heart.
