Thoratec won the European CE Mark approval to introduce its HeartMate PHP (Percutaneous Heart Pump) as a hemodynamic support system during high-risk percutaneous coronary interventions. The device is able to move up to five liters of blood per minute thanks to a tiny motor spinning at about 20,000 RPMs. It is inserted percutaneously via the femoral artery using a 14 French sheath and, once delivered into the aortic valve, expands to 24 French, eventually delivering near-normal blood flow through the vessel.
The HeartMate PHP was designed to impart low shear stress to the blood flowing through the pump, helping to reduce the chance of clot formation and the potential for a stroke.
More system features according to the product page:
– Wide 24F blood-flow pathways for over 4 L/min of mean flow
– Stable once placed across the aortic valve
– Internal driveline constructed of 10 interwoven microcables for maximum durability in tortuous anatomy
– Compact, lightweight console with a user-friendly touchscreen interface
– Reduces end-diastolic pressure, end-diastolic volume, and oxygen demand of the myocardium
