Abstract
Methods and apparatuses for pumping blood within a blood vessel are described. The methods and apparatuses can be used for renal decongestion by pumping blood through the kidney(s), thereby increasing a pressure gradient across the kidney(s). The apparatuses can include one or more inflatable elements that can be repeatedly inflated and deflated to cause a pumping action within the blood vessel. In some embodiments, the one or more inflatable elements are positioned within one or more stents.

A device for renal decongestion comprising:
- a hollow covered stent body having a first end and a second end;
- a first one-way valve at the first end of the hollow covered stent body;
- a second one-way valve at the second end of the hollow covered stent body;
- a balloon within the hollow covered stent body between the first one-way valve and the second one-way valve, the balloon configured to repeatedly deflate to pull blood through the first one-way valve into the hollow covered stent body and inflate to push blood through the second one-way valve from the hollow covered stent body in an antegrade direction;
- and
- a catheter connected to the hollow covered stent body.
