Patent number: 11850379Abstract: A launching catheter for targeting a second vessel from a first vessel includes a catheter including a proximal portion and a distal portion including a needle aperture and a flat rectangular radiopaque marker. The flat rectangular radiopaque marker disappears under fluoroscopy upon rotation to provide information about rotational alignment of the launching catheter. The launching catheter includes a needle configured to extend through the needle aperture. A method of aligning the catheter includes rotating the catheter in a first blood vessel until the marker has a thickness (e.g., minimal thickness) under fluoroscopy. The thickness indicates rotational alignment of the catheter.Type: GrantFiled: September 23, 2021Date of Patent: December 26, 2023Assignee: LimFlow GmbHInventors: Sophie Humbert, Katharina Wieczorek, Anika Nguyen, Marcus Wenzel

Patent number: 11446170Abstract: Apparatus and methods are described for performing percutaneous catheter-based interventional surgery. The apparatus comprises first and second devices that are located in adjacent body cavities, such as adjacent blood vessels, the first device being capable of transmitting a directional signal that can be received by the second device. The direction of the signal is correlated with the facility to direct therapy, such that improved accuracy in therapy placement is thereby achieved. Methods for treating patients utilising the means and apparatus are also provided.Type: GrantFiled: August 27, 2019Date of Patent: September 20, 2022Assignee: LimFlow GmbhInventors: Robert Julian Dickinson, Andrew Robert Pacey, Martin Terry Rothman, Ajay Kumar Jain
