摘要： An intravascular blood pump (1) comprises a catheter (5), a rotor (10), a housing (11) in which the rotor (10) is housed and a flexible drive shaft (12) extending through the catheter (5) and connected to the rotor. The drive shaft (12) comprises at least one outer layer (28) and at least one inner layer (29). The drive shaft (12) is rotatably supported in a proximal bearing (13) located proximally of the rotor (10). The outer layer (28) of the drive shaft (12) is absent or thinned at a location where the drive shaft (12) is supported in the proximal bearing (13).
