Abstract

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.

Abstract

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.

Abstract

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.

Abstract

The catheter device comprises a motor located at the proximal end of the catheter device, and a drive shaft which extends from the proximal end area of the catheter device to the distal end area and which drives a rotary element located at the distal end of the catheter device. The catheter device further comprises a tubular catheter shaft which encloses the drive shaft and which extends from the proximal end area to the distal end area of the catheter device. The drive shaft is connected to the motor at the proximal end of the catheter device by means of a coupling. The coupling is a magnetic coupling with a proximal magnet unit and a distal magnet unit. The proximal magnet unit is connected to the motor, and the distal magnet unit is connected to the drive shaft. The distal magnet unit is mounted in a coupling housing in a leaktight manner. The proximal end of the catheter shaft is connected to the coupling housing in a leaktight manner.

Abstract

The invention relates to a catheter device comprising a drive shaft connected to a motor and a rotor attached to the distal end region of the drive shaft. The rotor has a frarne structure comprised of a helical limiting frame and rotor struts extending radially inwards from the limiting frarne. The rotor struts are attached to the drive shaft on the ends thereof distant from the limiting frame. An electrical lining extends between the limiting frame and the drive shaft. The frame structure, made of an elastic material, is configured such that the rotor independently deploys after a forced compression.

Abstract

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.

Abstract

The catheter device comprises a motor located 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 of the catheter device. 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.
