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.
