Abstract
The invention relates to a pump device having a pump (8) and an energy supply device (5, 18), wherein the pump has a conveying element (9, 11) which conveys a fluid by means of supplied energy, wherein the pump has a transport state and an operating state, and wherein at least one first element (9, 9a, 10, 10′, 11) of the pump has a different shape and/or size in the transport state than in the operating slate. The operating safety of such a pump device is increased by a detection device (12, 20, 21, 22, 23, 24, 25, 27, 28, 29) which detects whether at least the first element is in the operating state with respect to shape and/or size by means of a sensor.
Claims23
1-15. (canceled)
An intravascular pump device, comprising:
- a first catheter having a proximal end and a distal end;
- a pump head configured to compress into a compressed state and expand into an expanded state, wherein the pump head is configured to move within the first catheter and the pump head elastically expands into the expanded state upon release from the first catheter;
- the pump head having a rotor with impeller blades, the impeller blades being elastically compressible and automatically elastically expandable, wherein the impeller blades are configured to convey a fluid by a supplied energy;
- and
- a sensor configured to produce an output signal indicative of a load on the rotor.
