Claim:
1. A blood pump comprising: an implantable pump for pumping blood having a rigid housing, a flow path extending within the housing in upstream and downstream directions and at least one movable element within the housing for impelling blood along the flow path; a first housing element and a second housing element within the housing having respectively a first interior surface and a second interior surface, the first and second interior surfaces confronting each other and cooperatively defining therebetween at least a portion of the flow path, the first housing element having an exterior surface defining a cavity external to the flow path; wherein the first housing element defines a first platform surface facing downstream at an oblique angle to a flow path axis and a second platform surface facing upstream at an oblique angle to the flow path axis, in which the first and second platform surfaces overlie the portion of the flow path, in which the first and second platform surfaces are within the cavity and extend respectively from first and second portions of the first interior surface which face in a same direction and confront the second interior surface, and wherein a first flow sensor is mounted to the first platform surface at an oblique angle to the flow path axis and a second flow sensor is mounted to the second platform surface at an oblique angle to the flow path axis.
