The invention relates to a rotor for a compressible fluid pump, in particular a blood pump that can be introduced through a blood vessel into a patient's body, wherein said rotor comprises one or more conveying elements (), is compressible and expandable between a first compressed state and a second radially expanded state, is made at least partially from a plastic reinforced with reinforcing elements, in particular fibers () and is provided for rotation about an axis of rotation (). According to the invention, the rotor is tensioned in the first, compressed state and free from external stresses in the second, expanded state. A third state exists, which the rotor () occupies in the operating state under load. The reinforcing elements, in particular fibers, extend in the rotor in the third state at least in sections in a stretched manner.

Rotor for a fluid pump and method and mold for the production thereof

The application relates to a pump, in particular blood pump. The pump comprises a drive shaft () which runs in an axial direction, a delivery element () which is connected to the drive shaft () in a distal region of this, and a housing () which surrounds the delivery element (). The delivery element () and the housing () are designed in a manner such that these automatically unfold after a forced compression. The housing () moreover comprises an inlet region () with at least one inlet opening (), a fluid-tight region () which surrounds a region of the delivery element (), and an outlet region () with at least one opening () for the exit of the pump medium. The delivery element () is arranged in a manner such that it projects into the outlet region ().

Pump, in particular a blood pump

The invention relates to a catheter device, having a catheter, an actuation device at a first end of the catheter and also a mechanical transmission element for transmitting a movement along the catheter to the actuation device, the actuation device having a coupling element which is connected to the transmission element and can be actuated by the latter relative to the longitudinal direction of the catheter in a first degree of freedom, and also a conversion element which can be actuated by the coupling element and which converts the actuation movement at least partially into a movement in a second degree of freedom. As a result, a combined movement at the distal end of the catheter can be produced particularly simply for compression and release of a functional element.

Catheter device having a catheter and an actuation device

The invention relates to a rotor for a fluid pump, in particular for use in the medical sphere, the rotor being compressible for bringing to the place of use and thereafter being expandable. The compressibility is assisted by the provision of cavities, in particular also production of the rotor at least partially from a foam.

Compressible rotor for a fluid pump

A flexible catheter with a drive shaft, and associated devices and systems. In some examples, the disclosure describes a flexible catheter with a drive shaft, with a sleeve surrounding the drive shaft and with a sheath surrounding the drive shaft and the sleeve, wherein the drive shaft, the sleeve and the sheath are pliable, wherein the drive shaft at a proximal end of the drive shaft comprises a coupling element for connecting the drive shaft to a drive motor, wherein the drive shaft at least regionally consist of a alloy which contains at least 10% by weight of chromium, nickel and cobalt in each case.

Flexible catheter with a drive shaft

The invention relates to a fluid pump, in particular to a liquid pump having a rotor with at last one rotor blade for conveying the fluid, the rotor being variable with respect to its diameter between a first, compressed state and a second expanded state. In order to produce a simple compressibility and expandability of the rotor of the pump, it is provided according to the invention that at least one rotor blade is deformable between a first state which it assumes in the compressed state of the rotor and a second state which it assumes in the expanded state of the rotor by means of a fluid counterpressure during a rotation of the rotor during pump operation.

Fluid pump with a rotor

A rotor for a pump has a housing and a rotor, and has at least one blade. The rotor is able to be actuated to rotate about an axis of rotation in order to convey a fluid in the axial or radial direction, and the rotor is able to be deformed in the radial direction between a first, radially compressed state and a second, radially expanded state. At a maximum speed of rotation of the rotor at which the power of the pump is at a maximum, the blade is essentially radially oriented, and/or the rotor has its maximum diameter.

Rotor for a pump, produced with a first elastic material

The invention relates to a radially compressible and expandable rotor for a pump having at least one impeller blade, wherein the impeller blade has an impeller blade body whose material is elastically deformable as well as at least one stiffening strut which is at least partially embedded in the material of the impeller blade body. The struts are designed suitably in size, shape and arrangement and are integrated in suitable hollow spaces of the impeller blade body for stabilizing the impeller blade. Elements with tensile strength can additionally be provided.

Radially compressible and expandable rotor for a pump having an impeller blade

The invention relates to a blood pump for the invasive application within a body of a patient comprising a rotor which is drivable about an axis of rotation and is radially compressible or expandable and which has a hub and at least one impeller blade fastened thereto, as well as comprising a housing which is compressible or expandable in the radial direction by an axial stretching or axial compression. The object of making both the rotor and the housing expandable and compressible in as simple a manner as possible is achieved in accordance with the invention in that a control body is provided which passes through the hub in the longitudinal direction, which is freely axially displaceable relative to the hub and which is coupled to the housing on the distal side of the rotor such that it exerts pulling and/or compression forces on the housing by a movement in the longitudinal direction with respect to the housing.

Blood pump for the invasive application within a body of a patient

The present invention relates to a pump, in particular a blood pump having a proximal and a distal end and a pump housing arranged therebetween, a driveshaft arranged in an interior of the pump housing along the longitudinal direction, a conveying element arranged on the driveshaft, and a cannula. Here, the pump housing, the shaft arrangement and the conveying element are coordinated with one another in such a way that these guarantee the best possible efficiency and longevity of the pump.
