    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: To provide a simple embodiment of a rotor for a fluid pump which is nevertheless very flexible in handling and compressible, in accordance with the invention a conveying blade is provided having at least two struts and a membrane spanned between them in the expanded state, wherein the struts each have at least one joint, in particular more than one joint, which enables an angling in a first direction in a first movement plane and bounds an overelongation beyond an elongation angle of in particular 180° in the opposite second direction. In particular when a plurality of joints are provided at the struts, they, and with them the conveying blades, are particularly flexible for simple compressibility.

    Abstract: To provide a simple embodiment of a rotor (2) for a fluid pump which is nevertheless very flexible in handling and compressible, in accordance with the invention a conveying blade is provided having at least two struts (12, 13, 14) and a membrane spanned between them in the expanded state, wherein the struts each have at least one joint, in particular more than one joint, which enables an angling in a first direction in a first movement plane and bounds an overelongation beyond an elongation angle of in particular 180° in the opposite second direction. In particular when a plurality of joints (15, 16, 17) are provided at the struts, they, and with them the conveying blades, are particularly flexible for simple compressibility.
