Abstract
A driver is disclosed for powering a pneumatically operated implantable device, such as an artificial heart with a left and a right ventricle. The driver includes a pair of compressors that each has a first and a second compression chamber. In a first mode of operation, both the first and the second compressor power the left and right ventricle of the artificial heart. In the event of a malfunction in the second compressor, the left and right ventricles of the artificial heart may be powered by the first compressor. Similarly, if a malfunction occurs in the first compressor, the artificial heart may be fully powered by the second compressor.
