Two layers of tubes imitate the heart

Scientists copy the special musculature of the heart by lining the organ with two layers of flexible, inflated tubes.

THE HEART IS MADE OF MUSCLES 1

The heart includes two layers of musc- les: an interior, trans-verse layer and an exterior, inclining one. The musculature, which automatically contracts, is nothing like what exists in the rest of the body.

AIR CAUSES MOTION 2

Scientists have developed two layers of transverse and inclining, flexible tubes, which hug the heart. The tubes are connected to an air pump outside the body, which alternately pumps air in and produces a vaccuum. The sleeve can be computercontrolled and will adjust to any heart.

THE PUMP IS GLUED ON 3

The pump is wrapped around the heart, so it can be adjusted to individual patients. It is attached with thread and special biological glue.
