Circulatory support system with diaphragm pump

A percutaneous circulatory support device system, comprising:

• a console including a processor;
• a cardiac pump including a controller coupled to the console, wherein the cardiac pump includes a pump housing having a distal end region and a proximal end region;
• a blood inlet positioned along the distal end region;
• a blood outlet positioned along the proximal end region;
• and
• a plurality of diaphragm pumps positioned within the pump housing;
• wherein the plurality of diaphragm pumps are configured to draw blood into the pump inlet and pump blood out of the blood outlet.

A percutaneous circulatory support device, comprising:

• a catheter shaft;
• a blood pump positioned at a distal end region of the catheter shaft, the blood pump including a pump housing having a distal end region and a proximal end region;
• a blood inlet positioned along the distal end region;
• a blood outlet positioned along the proximal end region;
• and
• a piston pump positioned within the pump housing;
• wherein the piston pump includes a piston configured to shift between a first position and a second position;
• wherein shifting the piston between the first position and the second position draws blood into the pump inlet and pumps blood out of the blood outlet.
