发明名称 Catheter device
摘要 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.

主权项 1. A catheter device comprising a drive shaft connected to a motor; a rotor mounted on the drive shaft at the distal end section wherein the rotor is made of an elastic material such that, after forced compression, the rotor unfolds automatically;an expandable or compressible pump housing which encompasses the rotor, wherein the pump housing comprises a distal connection section, a conical intake section, a pump section, a conical outlet section and a proximal connection section and wherein the pump housing is formed by a mesh comprising apertures, wherein the apertures are closed by an elastic covering at least in the area of the pump section and wherein apertures in the conical intake section are larger than apertures in the pump section, wherein the apertures in the pump section all have a substantially uniform size.
