Listen to the heartbeat ... er, hemopump.

Listen to the heartbeat ... er, hemopump

Sometimes the best things come in small packages, and the Nimbus Hemopump may become a tiny-but-cherished technological gift for those fighting life-threatening heart disease. Threaded into the top of the heart through an artery in the groin, the newly developed miniature pump pulls blood through an attached tube that hangs into the left ventricle. With a turbine blade that rotates 25,000 times a minute, the pump then pushes the ventricle's blood out through the aorta and into the rest of the body.

Developed by Nimbus Medical Inc. of Rancho Cordova, Calif., the pencil-eraser-sized device is designed to temporarily take over all of the heart's blood-pumping responsibilities, thus allowing a damaged heart to begin healing. Researchers recently used the pump in a human patient whose body was rejecting his transplanted heart, and have begun larger studies necessary for Food and Drug Administration approval.
