[13] [14] [15] In some pulsatile pumps (that use compressed air as an energy source [16]), the volume occupied by blood varies during the pumping cycle. If the pump is contained inside the body then a vent tube to the outside air is required. Continuous-flow VADs are smaller and have proven to be more durable than pulsatile VADs. [17]
Impella heart pumps are percutaneous microaxial pumps that act as mechanical circulatory support devices in patients in need of hemodynamic support. [11] The pumps are mounted on support catheters and typically inserted through the femoral artery, although axillary and subclavian artery approaches are not uncommon. [12]
The intra-aortic balloon pump (IABP) is a mechanical device that increases myocardial oxygen perfusion and indirectly increases cardiac output through afterload reduction. It consists of a cylindrical polyurethane balloon that sits in the aorta , approximately 2 centimeters (0.79 in) from the left subclavian artery . [ 1 ]

Then doctors at NYU Langone Health devised a novel one-two punch: Implant a mechanical pump to keep her heart beating and days later transplant a kidney from a genetically modified pig.
The first transplant surgery to combine a mechanical heart pump as well as a gene-edited pig kidney has been completed at NYU Langone Health, the system said Wednesday.
An artificial heart is a device that replaces the heart.Artificial hearts are typically used as a bridge to heart transplantation, but ongoing research aims to develop a device that could permanently replace the heart when a transplant—whether from a deceased human or, experimentally, from a genetically engineered pig—is unavailable or not viable.
Berlin Heart manufactures two types of VADs: implantable and paracorporeal. INCOR is an axial-flow pump for support of the left ventricle. In this system, the pump is implanted directly next to the heart and is connected to the heart by cannula. The blood coming from the heart flows into the INCOR axial pump. [7]
