The catheter device comprises a drive shaft connected to a motor, and a rotor mounted on the drive shaft at the distal end section. The rotor has a frame structure which is formed by a screw-like boundary frame and rotor struts extending radially inwards from the boundary frame. The rotor struts are fastened to the drive shaft by their ends opposite the boundary frame. Between the boundary frame and the drive shaft extends an elastic covering. The frame structure is made of an elastic material such that, after forced compression, the rotor unfolds automatically.

Catheter device

The invention relates to a method for producing a device for material exchange between two mediums, in which at least one mat of semipermeable hollow fibres () is wound onto a winding core (), which has at least one core opening () in its outer surface for a first in- or out-flowing medium, and the winding core () is arranged in an axially extending housing () having at least one housing opening () for the first in- or out-flowing medium, and the axial end regions of the housing () are sealed by an adhesive () arranged around the hollow fibres (), wherein at least one chamber region () surrounding the hollow fibres () is formed via the adhesion between the axial end regions () of the housing () and between the winding core () and the housing (), through which chamber region the first medium can flow via the core opening () and the housing opening (), wherein the axial distance between the core opening () and the housing opening () is adjusted to a desired value of multiple possible values via the axial shifting of the winding core () relative to the hollow fibre winding () arranged around the winding core () and relative to the housing (), and the hollow fibres () are adhered to the side of the housing () near to the housing opening () in a region between the axial end surface of the housing and the housing opening (), and the hollow fibres () are adhered to the side of the housing () near to the core opening () in a region between the axial end surface of the housing and the core opening (). The invention also relates to a number of multiple devices for material exchange between two mediums, wherein all devices comprise at least identical housings () and winding cores () that are identical at least in regions.

Tubular fiber membrane for material exchange and method of making same

A system for the extracorporeal elimination of carbon monoxide, includes at least one pump and a gas exchange chamber, wherein the at least one pump can be connected to the blood circulatory system of a person by way of a first tube section connectable to a cannula and is connected to a gas exchange chamber via a second tube section, wherein the system is configured to transfer blood, via the first tube section, from the blood circulatory system of the person by way of at least one pump into the gas exchange chamber, and to return the blood from the gas exchange chamber to the blood circulatory system of the person via the same first tube section.

System for the extracorporeal elimination of carbon monoxide

The catheter device comprises a motor at the proximal end of the catheter device and a drive shaft, extending from the proximal end section to the distal end section of the catheter device, for driving a rotating element located at the distal end of the catheter device. The catheter device also comprises a hose-like catheter body which encompasses the drive shaft and extends from the proximal end section to the distal end section. At the proximal end of the catheter device, the drive shaft is connected to a motor by a clutch. The clutch is a magnetic clutch with a proximal and a distal magnet unit. The proximal magnet unit is connected to the motor and the distal magnet unit to the drive shaft. The distal magnet unit is mounted fluid-tight in a clutch housing. The proximal end of the catheter body makes a fluid-tight connection with the clutch housing.
