See full text

This centrifugal blood pump apparatus includes an impeller (10) provided in a blood chamber (7), and a plurality of coils (20) provided in a motor chamber (8) for driving the impeller (10) to rotate with a dividing wall (6) interposed therebetween. A flexible substrate (23) in the shape of a strip is arranged to surround outer circumferences of the plurality of coils (20), and is connected to the plurality of coils (20) and a connector (24). A driving voltage (VU, VV, VW) is externally supplied to the plurality of coils (20) via the connector (24) and the flexible substrate (23). Thus, assembling workability, productivity and reliability are improved.
