Publication number: 20250228565Abstract: A catheter system for a interventional procedure includes a bendable and/or steerable extension arm and a guiding sheath. The extension arm is movable along the sheath or fixed at the distal end so that it projects in an operation position from the distal end. The extension arm has an inner guidewire lumen. At least one alignment component having a collapsed state and being configured to expand into an expanded state is advanceable to or attached to the guiding sheath at a pre-defined position within the distal section but proximally from its distal end. The alignment component includes a plurality of struts distributed on the circumference. Each strut of the struts runs at least sectionwise into radial direction and/or is inclined with regard to the longitudinal axis in the expanded to produce a force directed radially outwardly and to support the alignment component on the patient's heart, vasculature and/or implant.Type: ApplicationFiled: July 7, 2023Publication date: July 17, 2025Inventors: Georg Nollert, Tobias Kissling

Publication number: 20220331098Abstract: An artificial heart valve includes support structure having a first end and second end and defining an interior of the valve. A covering covers the support structure and includes an intermediate portion with a plurality of intermediate strip-shaped sections having cuts between them. Some are attached to the stent and others are not so that a closed configuration prevents retrograde blood flow into an interior of the stent with the free strip-shaped sections abutting the stent and overlapping or abutting the attached strip-shaped sections to prevent retrograde blood flow into the interior. An open configuration is formed with the unattached strip-shaped sections lifting from the stent to allow antegrade blood flow from the interior of the stent.Type: ApplicationFiled: September 23, 2020Publication date: October 20, 2022Inventors: Georg Nollert, Tobias Kissling

Patent number: 9237926Abstract: The ablation of tissue in a cardiac wall is performed by introducing an endocardial catheter into the interior of a heart and an epicardial catheter is placed on the cardiac wall. With the aid of an electromagnet and a counter-element, which can be permanently magnetized or can also be an electromagnet, the two catheters are mutually attracted in such a way that electrodes come into contact with opposite sides of the cardiac wall such that the electrodes are optimally positioned. The use of a catheter with a plurality of such electrodes in a row enables the removal of whole lines of destroyed cardiac wall tissue by ablation.Type: GrantFiled: December 22, 2011Date of Patent: January 19, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Georg Nollert, Martin Ostermeier
