Publication number: 20180228952Abstract: 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: February 8, 2018Publication date: August 16, 2018Inventors: Joachim-Georg Pfeffer, Thomas Schmitz-Rode, Rolf W.

Patent number: 5102415Abstract: A triple catheter for removing of blood clots from arteries and veins is equipped with an outer catheter (1) that can be inserted into a blood vessel and an inner catheter (5) with an inflatable baloon (6) at its distal end that can be inserted into the outer catheter (1). The inner catheter (5) is surrounded by an intermediate catheter (2) also inserted into the outer catheter (1). The intermediate catheter (2) has a radially expandable distal end receptacle (3) made of an elastic mesh structure of spring wires or plastic monofilaments covered by or embedded in an elastic plastic coating. A very small puncture channel is required for the insertion of such a triple catheter through the wall of a blood vessel.Type: GrantFiled: August 30, 1990Date of Patent: April 7, 1992Inventors: Rolf W.
