Abstract

A ventricular assist catheter pump comprises a catheter, a power device, a controller, a pacemaker and a seal device. The catheter is inserted into an aorta, one end of the catheter is connected with the power device while the other end of the catheter is a free end with a blood flow section, the blood flow section is circumferentially provided with holes at intervals along a same section, and the holes are open diagonally upwards. The seal device is arranged on the blood flow section, a pace-making guide wire is arranged at the upper end of an aortic valve and connected with the pacemaker, and the pacemaker is connected with the controller which is connected with the power device. The ventricular assist catheter pump is implanted by peripheral vessel minimally invasive operations to keep pulsation characteristics of a heart, and direction uniformity of blood flow flowing into the aorta and blood flow flowing out from the heart is guaranteed. In addition, by a temporary pacemaker control system, synchronous operations of the ventricular assist catheter pump and a heart ventricle are realized, and accordingly ventricular assist efficiency of the ventricular assist catheter pump is further improved.

Description

technical field [0001] The invention relates to the field of cardiac assistance, in particular to a ventricular assist catheter pump. Background technique [0002] Ventricular assist device is recognized worldwide as the most effective treatment for various types of end-stage heart failure. From the development of the first generation pneumatic blood pump and the second generation axial flow blood pump in the 1960s to the third generation suspension blood pump today, several generations of scientists have experienced the arduous research process. [0003] Our country started research on ventricular assist devices in the early 1980s. Despite the efforts of several generations, there is still a big gap compared with foreign countries. So far, there is no commercial domestic cardiac assist device for clinical application. Although there are commercial ventricular assist devices in foreign countries, the price of a set of devices is as high as RMB 500,000-1 million, but the pri...
