An intravascular blood pump for percutaneous insertion into a patient's vasculature includes a pumping device (30) and a supply catheter (36). The pumping device includes a pump section having a blood flow inlet, a blood flow outlet, and an impeller conveying blood from the inlet to the outlet, and a drive section connected to the pump section and adapted to drive the impeller. The supply line supplies the drive section with electrical energy to drive the impeller. A supply conduit (36) supplies electrical energy to drive the impeller. The pump section (32) is arranged axially between the drive section (31) and the supply line (36). The pump section comprises a flexible bendable sleeve (35), while the power line (44) is arranged across the sleeve (35) in such a way as to prevent the sleeve (35) from cracking upon bending. 一种经皮插入患者脉管系统中的血管内血泵，其包括泵送装置(30)和供应导管(36)。泵送装置包括泵区段，泵区段具有血流入口、血流出口及将血液由入口输送至出口的叶轮，其还包括连接至泵区段并适于驱动叶轮的驱动区段。供应管线供应驱动区段用以驱动叶轮的电能。供应导管(36)供应用以驱动叶轮的电能。泵区段(32)轴向地布置在驱动区段(31)及供应管线(36)之间。泵区段包括柔性可弯曲的套管
