    Abstract: 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).

    Abstract: The invention relates to a fluid pump or rotatary cutter having at least one first element (9′″, 10′″) which can be brought from a transport state into an operating state by changing at least one mechanical property. Such a pump can, for example, be a blood pump for the medical microinvasive area. The object of achieving a transition between the transport state and the operating state which is as comfortable as possible and in so doing leaving a freedom in the design of corresponding apparatus, in particular of a pump, which is as large as possible, is achieved using the means of the invention in that the first element at least partly comprises a material (24, 25, 26, 27) or can be filled with a material or material mixture which passes through a chemical reaction, in particular cross-linking, or a crystallization for transition into the operating state.

    Abstract: An intravascular blood pump comprises a catheter, a rotor, a housing in which the rotor is housed and a flexible drive shaft extending through the catheter and rotatably supported in a proximal bearing located proximally of the rotor. The proximal bearing comprises a bearing sleeve and an outer bearing ring. The bearing sleeve comprises a proximal portion located proximally of the outer bearing ring, the proximal portion of the bearing sleeve forming an axial bearing with a proximal surface of the outer bearing ring. The bearing sleeve further comprises a distal portion extending from the proximal portion of the bearing sleeve distally into the outer bearing ring, wherein the distal portion of the bearing sleeve forms a radial bearing with the outer bearing ring.

    Abstract: The subject matter of the present invention is a pump arrangement, in particular for use in the body's own vessels, having a pump and a sheath receiving the pump, bounding a flow passage and having a distal intake opening and a proximal outflow opening for producing a driving flow by means of the pump, wherein the pump is arranged in a first fluid-tight section having the distal intake opening and a second fluid-tight section includes the proximal outflow opening. In accordance with the invention, a further inlet opening is present between the first section, and the second section and is arranged between the intake opening and the outflow opening, with the first section and the second section being arranged with respect to one another such that the inlet opening opens into the flow proximal to the pump.
