1. A medical device system for treating a heart, the system comprising:
a control system having a processor and a pump;
a first elongate shaft having a proximal end coupled to the control system at a first location and a distal end, wherein a first expandable member is coupled to the first elongate shaft adjacent to the distal end of the first elongate shaft, wherein the first elongate shaft includes a first aperture positioned proximal to the first expandable member, and wherein the first expandable member is configured to be positioned in the superior vena cava after the first elongate shaft has been tracked through the jugular vein;
a second elongate shaft having a proximal end coupled to the control system at a second location distinct from the first location and a distal end, wherein a second expandable member is coupled to the second elongate shaft adjacent to the distal end of the second elongate shaft, wherein the second elongate shaft includes a second aperture positioned proximal to the second expandable member, and wherein the second expandable member is configured to be positioned in the inferior vena cava after the second elongate shaft has been tracked through the femoral vein;
a first sensing member extending within a portion of the first elongate shaft and through the first aperture, wherein the first sensing member includes a first end positioned proximal the first expandable member and a second end coupled to the control system, the first sensing member designed to sense a first parameter; and
a second sensing member extending within a portion of the second elongate shaft and through the second aperture, wherein the second sensing member includes a first end positioned proximal the second expandable member and a second end coupled to the control system, the second sensing member designed to sense a second parameter; and
a third sensing member having a first end configured to be positioned distal to the first expandable member, extending distally out of the distal end of the first elongate shaft, and adjacent the right atrium and a second end coupled to the control system, the third sensing member designed to sense a third parameter;
wherein the processor is configured to assess a blood flow based on the first parameter, the second parameter or both the first parameter and the second parameter, and wherein the processor communicates with the pump to expand or contract the first expandable member, the second expandable member or both the first and the second expandable members based on a change in the blood flow.
