  • Publication number: 20160106898
    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.

  • Publication number: 20150258262
    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.

  • Publication number: 20150245783
    Abstract: The invention relates to a rod-shaped body (1) comprised of one or more filaments (2) and of a non-ferromagnetic matrix material (3). The matrix material (3) surrounds the filament(s) (1) and/or adheres them to one another. The rod-shaped body is also comprised of a dopant consisting of particles that generate magnetic resonance tomographic artifacts that is introduced into the matrix material (3). Rod-shaped bodies of this type can be used to construct guide wires, catheters and other instruments to be used in minimally invasive surgical interventions.

  • Publication number: 20140018839
    Abstract: The present invention relates to a stent for splinting a nasal passage. The stent (1) consists of a braided tubular support body (2) which, in unloaded state, has a diameter of at least 4 mm and a length in the range of 25 to 120 mm and particularly of 25 to 100 mm. The stent may have a widened section (15) at the proximal end for splinting of the nasal alar. It may alternatively or in combination have a fixation section (3) at the proximal end of the stent (1) for fixation of the stent (1) in a nasal passage of a user. When fixed the fixation section (3) protrudes from the nostril of the user and can be fixed outside of the nose.
