The invention relates to a fluid pump device, in particular for the medical application, with a compressible pump housing and rotor, as well as with an actuation means which runs in the sleeve and on whose end the fluid pump is arranged. In order to utilize all possibilities of a space-saving arrangement of the respective pump housing of the rotor, which is compressible per se, and as the case may be, a bearing arrangement, the mentioned elements are displaceable to one another in the axial direction compared to an operation position. In particular these elements may be end-configured by way of an axial movement of the drive shaft after the assembly.

Fluid pump changeable in diameter, in particular for medical application

The present invention relates to a supply device for a channel, in particular within a hollow catheter, and to a method for operating a supply device of this type that supplies a channel with a liquid and has two pumps arranged at points of the channel distanced from one another, characterised in that the parameter values of at least one operating parameter of both pumps are coordinated with one another in a controlled manner. As a result of the method, interruption-free and precisely controllable operation is to be ensured with simple structural means, in particular in the case of use of wear-free diaphragm pumps.

Method for operating a supply device which supplies a liquid to a channel, and supply device, hollow catheter, and catheter pump

A catheter device having a catheter () in which a rotating shaft () which is made at least partially from a magnetic material is arranged, and a separating device which contains a housing () surrounding the rotating shaft and having a cavity containing a magnetic body ('), the magnetic body being arranged downstream from a point at which the shaft () exits the catheter () which it surrounds with respect to the direction of flow of the fluid through the catheter.

Catheter device comprising a separating device for retaining magnetic particles contained in a fluid and protection device for a functional element

The invention relates to a fluid pump or rotary cutter having at least one first element () 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 () 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.

Pump or rotary cutter for operation in a fluid

A flexible shaft arrangement is described herein having a flexible hollow shaft () which has an end at the drive side and an end at the output side, wherein the hollow shaft is reinforced sectionally between these ends by a core () extending in its interior. Stiffer and more flexible sections can hereby be selectively positioned within the shaft arrangement.

The invention relates to a fluid pump or rotary cutter having at least one first element (′″) 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 () 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.

The subject matter of the present invention is a pump arrangement, in particular for use in the body's own vessels, having a pump and a sheath receiving the pump, bounding a flow passage and having a distal intake opening and a proximal outflow opening for producing a driving flow by means of the pump, wherein the pump is arranged in a first fluid-tight section having the distal intake opening and a second fluid-tight section includes the proximal outflow opening. In accordance with the invention, a further inlet opening is present between the first section, and the second section and is arranged between the intake opening and the outflow opening, with the first section and the second section being arranged with respect to one another such that the inlet opening opens into the flow proximal to the pump.

Pump arrangement

A fluid pump device changeable in diameter is provided. The device has a pump housing which is changeable in diameter and with a rotor which is changeable in diameter. The device has at least one delivery element for fluid, as well as a drive shaft on which the rotor is rotatably mounted. A bearing arrangement is arranged on the drive shaft or its extension, at the distal end of the drive shaft behind the rotor seen from the proximal end of the drive shaft. The bearing arrangement has struts, which elastically brace between a hub of the bearing arrangement and the pump housing.
