[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]
The Dodrill–GMR heart machine, considered by some to be the first operational mechanical heart was successfully used while performing heart surgery. [1] [2] The machine performs the functions of the heart, allowing doctors to detour blood and stop the heart of a patient during an operation. The machine is external of the body and is only used ...

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]
Forest Dewey Dodrill (January 26, 1902 – June 28, 1997) was a medical doctor at Harper University Hospital at Wayne State University in Michigan who performed the first successful open heart surgery using a mechanical pump. [1] [2]
The Dodrill-GMR heart machine, considered by some to be the first operational mechanical heart was successfully used while performing heart surgery on Opitek. Forest Dewey Dodrill , a surgeon at Wayne State University's Harper Hospital in Detroit, used the machine to bypass Opitek's left ventricle for 50 minutes while he opened the patient's ...
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 ]
