[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 ...
An artificial heart is an artificial organ device that replaces the heart.Artificial hearts are typically used to bridge the time to complete heart transplantation surgery, but research is ongoing to develop a device that could permanently replace the heart in the case that a heart transplant (from a deceased human or, experimentally, from a deceased genetically engineered pig) is unavailable ...
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.

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.
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]
With the 2001 Thermo Cardiosystems merger, Thoratec acquired the HeartMate Left Ventricular Assist System, an implanted VAD for end-stage heart patients. A landmark three-year study of 129 patients at 22 major medical centers, called REMATCH (Randomized Evaluation of Mechanical Assistance for the Treatment of Congestive Heart Failure) and published in November 2001, found that the HeartMate VE ...
