This heart model is enlarged to twice the actual size for ease of observation and demonstration, making it perfect for patient education. Attachable/detachable bypass vessels allow demonstration of single-, double-, and triple-coronary bypasses. Use the bypass tubing, complete with built-in quick-connects, to instantly install single, double, or triple bypasses, representing grafts of the saphenous vein of the lower leg, to connect the ascending aorta to the coronary arteries. To demonstrate the anatomy of the normal healthy heart, simply detach all bypass vessels. Overall dimensions: 7" x 7" x 17". Multicolor.
