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.

First claim

The invention claimed is:

1. A system comprising:
a compressible and expandable heart pump,
a catheter coupled to the heart pump; and
a container for the heart pump, the container comprising:
a first receiving space for the heart pump, wherein the first receiving space is delimited by one or more closure elements,
wherein the one or more closure elements leave free an opening sized for passage of the catheter into the first receiving space such that the heart pump is located in the first receiving space and the catheter projects through the opening out of the first receiving space,
wherein the opening is sized such that the heart pump is radially compressed during extraction of the heart pump from the first receiving space through the opening.

2. The system of claim 1 , wherein the first receiving space is sized to contain the heart pump within the first receiving space with the heart pump in a radially expanded state, wherein in the radially expanded state, a diameter of the heart pump is larger than a width of the opening.

3. The system of claim 1 , the one or more closure elements are made of a plastic material.

4. The system of claim 3 , wherein the plastic material is a plastic foil.

5. The system of claim 1 , wherein the one or more closure elements comprise two half-shell-shaped closure elements that are joined together.

6. The system of claim 1 , wherein the one or more closure elements comprise first and second closure elements that are undetachably connected to one another.

7. The system of claim 1 , wherein the one or more closure elements comprise first and second closure elements and the opening is formed between the first and second closure elements.

8. The system of claim 1 , wherein the one or more closure elements comprises a first closure element that is configured as part of a blister, wherein the blister receives at least the catheter.

9. The system of claim 8 , wherein the first closure element forms a capture shell for fluid in a region of the first receiving space.

10. The system of claim 1 , wherein the opening at least partly consists of a cylinder-symmetrical channel.

11. The system of claim 10 , wherein the cylinder- symmetrical channel narrows outwardly from inside of the first receiving space.

12. The system of claim 11 , wherein the opening comprises an edge configured to support a hollow-cylindrical sheath element in an axial direction of the channel, wherein the hollow-cylindrical sheath element is displaceable along the catheter.

13. The system of claim 1 , further comprising a sheath element through which the catheter passes, wherein the sheath element is provided on the catheter in a freely displaceable manner.

14. The system of claim 1 , wherein the first receiving space is delimited by at least two closure elements which are joined along a joining line, wherein the joining line runs essentially perpendicularly to a passing direction of the compressible and expandable heart pump.

15. The system of claim 1 , wherein the first receiving space is delimited by at least two closure elements which are joined along a joining line, wherein the joining line runs in a cross section of the first receiving space which is larger than the cross section of the opening for the passage of the catheter on removal of the compressible and expandable heart pump.

16. The system of claim 1 , wherein the first receiving space comprises a second opening.

17. The system of claim 16 , wherein the second opening is sized such that the compressible and expandable heart pump is introducible into the first receiving space through the second opening without radially compressing the heart pump.

18. The system of claim 16 , further comprising a cover configured to close the second opening.
