Publication number: 20240082541Abstract: 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: September 12, 2023Publication date: March 14, 2024Applicant: AIS GMBH AACHEN INNOVATIVE SOLUTIONSInventors: Joachim Georg Pfeffer, Thomas Schmitz-Rode, Rolf W.

Publication number: 20210236017Abstract: 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.Type: ApplicationFiled: April 20, 2021Publication date: August 5, 2021Inventors: Joachim-Georg Pfeffer, Rolf W.
