Assisted Circulation Categories.
 |
Counterpulsation - A technique for assisting the circulation by decreasing the afterload of the left ventricle and augmenting the diastolic pressure. It may be achieved by intra-aortic balloon, or by implanting a special pumping device in the chest, or externally by applying a negative pressure to the lower extremities during cardiac systole. |
|
Heart-Assist Devices - Small pumps, often implantable, designed for temporarily assisting the heart, usually the left ventricle, to pump blood; they consist of a pumping chamber and a power source, which may be partially or totally external to the body and activated by electromagnetic motors; the devices are used after myocardial infarction or to wean the repaired heart from the heart-lung machine after open-heart surgery. |
