Publication number: 20150258262Abstract: 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.Type: ApplicationFiled: May 29, 2015Publication date: September 17, 2015Inventors: JOACHIM-GEORG PFEFFER, THOMAS SCHMITZ-RODE, ROLF W.
