The Impella is an FDA cleared, percutaneous ventricular assist device designed to provide a patient’s heart with hemodynamics support. The catheter-based heart pump is manufactured by Abiomed, headquartered in Danvers, Massachusetts. The Impella 2.5 received FDA 510(k) clearance in June 2008.) 〔(【引用サイトリンク】title= Abiomed Receives 510(k) Clearance from FDA for Impella 2.5 )〕 The Impella is currently the world's smallest heart pump. The whole device is less than the width of a pencil, and the pump is tinier than an eraser.〔(【引用サイトリンク】title= World's smallest heart pump reaches thousands of patients across US )〕 This tiny device acts like a temporary artificial heart as it maintains blood flow through the body during a cardiac procedure. It works by pumping blood throughout the body when the heart is too weak to do it itself – providing time for the heart to rest and heal.〔(【引用サイトリンク】title= World's smallest heart pump reaches thousands of patients across US )〕 Doctors insert the Impella, a minimally invasive mechanical circulatory support (MCS) device, into the heart percutaneously, through a small hole in the leg, to provide hemodynamic support for patients. The procedure is typically performed in a catheterization lab (cath lab). This is different than traditional heart therapies which require doctors to open the chest. 〔(【引用サイトリンク】title= World's smallest heart pump reaches thousands of patients across US )〕 A recent study by Yale University published in the Journal of the American College of Cardiology, entitled “National Trends in the Utilization of Short-term Mechanical Support,” found a significant increase – more than 1,500 percent – in the use of minimally invasive percutaneous MCS devices – between 2007 and 2011.〔(【引用サイトリンク】title= National trends in the Utilization of Short-Term Mechanical Circulatory Support )〕 As of 2014, 910 hospitals in the United States have acquired Impella products, with over 2,000 implanting physicians. Impella is now included in five sets of clinical practice guidelines: 1) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Impella」の詳細全文を読む スポンサード リンク
