    Abstract: The invention relates to a fluid pump or rotary 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 the 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: The invention relates to a catheter device (100) comprising a catheter (68) for insertion into a living being and at least one lumen (69, 70, 74, 79) for guiding a fluid flow within a section of the catheter device, and comprising a valve for controlling a fluid flow, in particular through a catheter, having a valve control chamber (12, 12a), into which an inlet opening (1a) of an inlet channel (1) and an outlet opening (2a) of an outlet channel (2) open, and further having a closure element (5, 13, 17) which can be moved in the valve control chamber (12, 12a) in a controlled manner and which, in at least a first position (I), closes the outlet opening (2a), in at least a second position (II) closes the inlet opening (1a), and which, in at least a third position (III), keeps open a connecting channel between the inlet opening (1a) and the outlet opening (2a), a valve train (A, A′, B, B′, 3, 14, 18) being provided and optionally moving the closure element (5, 13, 17) to at least the first, second or third position, and the at least one lumen (68, 70, 74, 79) being fluidically connected to the inlet channel or the outlet channel.
