摘要
Methods for using blood pumps to treat heart failure are disclosed. The pump (10) is mounted on an interior of a stent (25), does not occupy the entire lumen and the stent (25) is releasably mounted on a distal end of a catheter. The distal end of the catheter is inserted into a peripheral artery and advanced to position the stent (25) at a region of interest within the descending aorta, the ascending aorta or the left ventricle. The stent and the pump (10) are released from the catheter and the pump (10) is activated to increase blood flow downstream of the pump (10). The pump (10) can also be positioned in the vena cava or used to treat right-sided heart failure following the insertion of an LVAD or to improve venous return in patients with varicose veins. Non-stent pumps are described for insertion between vein and aorta and between the vena cava and pulmonary artery designed for use during cardiac surgery.
