摘要：一种血泵装置、用于插入血泵的系统及工作方法。血泵装置通过预设在血泵组件（10）中的牵引丝（20），使得牵引丝（20）可以带动导丝（40）沿牵引丝（20）的轨迹穿过血泵组件（10）。该方式使得术者不需要进行导丝（40）穿孔操作，导丝（40）穿过血泵组件（10）的时间短，还可以使得导丝（40）很容易的穿过血泵组件（10），不会对血泵组件（10）内的零件造成划伤，并且在导丝（40）的近端随着牵引丝（20）从流出窗口（15）伸出时，牵引丝（20）已经移出导管泵，术者不用进行导引管移出操作，减少了手术过程操作步骤。

摘要： Disclosed is a mechanical circulatory support system for transcatheter delivery to the heart, having a removable guidewire aid to assist with inserting the guidewire along a path that avoids a rotating impeller. The system may comprise a catheter shaft and a circulatory support device carried by the shaft. The device may comprise a tubular housing, an impeller and the guidewire aid. The guidewire aid may include a removable guidewire guide tube. The guide tube may enter a first guidewire port of the tubular housing, exit the tubular housing via a second guidewire port on a side wall of the tubular housing on a distal side of the impeller, enter a third guidewire port on a proximal side of the impeller, and extend proximally through the catheter shaft.

摘要： An intravascular blood pump for percutaneous insertion into a patient's vasculature comprises a pumping device (30) and a supply catheter. The pumping device comprises a pump section with a blood flow inlet, blood flow outlet, and impeller for conveying blood from the inlet to the outlet and further comprises a drive section connected to the pump section and adapted to drive the impeller. The supply line supplies the drive section with electric energy for driving the impeller. An anchoring structure (25A) is provided at a distal end region of the intravascular blood pump. A connecting catheter (25) may be attached to the anchoring structure from distally in order to guide the intravascular blood pump through the patient's vasculature in a distal direction.
