    Abstract: The invention relates to a fluid pump comprising at least one impeller blade (1, 1′, 1″) which is rotatable about an axis of rotation (3) and conveys a fluid in operation and comprising a support device (4, 6, 7, 8, 9, 10, 12, 12′, 13, 13′, 14, 14′, 15, 17) which supports the at least one impeller blade (1, 1′, 1″) in at least one support region, wherein the support device is changeable between a first state in which the rotor is radially compressed and a second state in which the rotor is radially expanded; and wherein at least one impeller blade extends at least partly radially inwardly with respect to the axis of rotation (3) from the support region/support regions in the radially expanded state of the rotor.

    Abstract: In a rotor for a fluid pump which is made radially compressible and expandable and has a hub (4) and at least one conveying element (10, 11, 19, 20) which has a plurality of struts (12, 13, 14, 15, 16, 21, 22, 27, 28) and at least one membrane (18) which can be spanned between them, provision is made for a design in accordance with the invention which is as simple and inexpensive as possible that at least one first group of struts is pivotable in a pivot plane, starting from a common base, and can thus be spanned open in the manner of a fan, wherein the conveying element lies along the hub and contacts it over its full length in the expanded state to avoid a pressure loss at the margin of the conveying element between it and the hub and thus to realize an optimum efficiency.

    Abstract: The invention relates to a container for a heart pump device with a first receiving space for a compressible and expandable heart pump, wherein the first receiving space is delimited on several sides, in particular on all sides, by one or more closure elements and is closed off to the outside for preventing a contacting of the heart pump, wherein the closure elements) leave free an opening for the passage of a catheter from the outside into the first receiving space, wherein the diameter of the opening is dimensioned such that the heart pump can pass this exclusively in a condition which is at least partly compressed compared to the expanded condition. For implantation, the heart pump in the container can firstly be operated by trial in the container whilst feeding a rinsing fluid and can then be pulled through the opening amid simultaneous compression, into a sheath element.

    Abstract: A fluid pump includes a rotor with at least one rotatable impeller blade, the rotor having a compressed state and an expanded state, and a support device coupled to an outer radial edge of the at least one impeller blade. The support device is changeable between a first state in which the support device is radially compressed associated with the compressed state of the rotor, and a second state in which the support device is radially expanded associated with the expanded state of the rotor. In the expanded state of the rotor, the at least one impeller blade extends at least partly radially inward from the support device. The support device is a ring that at least partly surrounds the at least one impeller blade, the ring having a longitudinal axis parallel to an axis of rotation of the rotor.
