Patent number: 11292173Abstract: According to the invention an apparatus for extrusion of a structured extrudate, which can be introduced into a human or animal body, is provided. This apparatus comprises an extrusion apparatus with a housing, whereas the housing has a revolving lateral wall which at a front end in the direction of production is provided with a nozzle wall with an outlet nozzle, and in the direction of production prior to that with a global sleeve, whereas the space in the housing between the global sleeve, the lateral wall and the outlet nozzle confines an extrusion space, and the housing in the region of the extrusion space can be connected to a polymer feeding appliance. In the global sleeve at least one guide channel extending in the direction of production is provided in order to be able to insert at least one rod-shaped body from a feeding appliance for rod-shaped bodies into the extrusion space, whereas the at least one guide channel is arranged in about straight alignment to the outlet nozzle.Type: GrantFiled: August 31, 2016Date of Patent: April 5, 2022Assignee: MaRVis Interventional GmbHInventors: Arelí Graciela Luttmann, Nasib Dlaikan-Campos, Klaus Düring

Patent number: 11006850Abstract: The invention relates to a rod-shaped body comprised of one or more filaments and of a non-ferromagnetic matrix material. The matrix material surrounds the filament(s) 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. 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: GrantFiled: December 19, 2018Date of Patent: May 18, 2021Assignee: MARVIS INTERVENTIONAL GMBHInventors: Joachim-Georg Pfeffer, Rolf W. Günther, Thomas Schmitz Rode

Patent number: 10758316Abstract: The invention relates to a rod-shaped body comprising a central section and a peripheral section, wherein the central section is arranged in the center of the rod-shaped body and is enclosed by the peripheral section. Both the central section and the peripheral section substantially extend along the entire length of the rod-shaped body. The central section comprises at least one non-metallic fiber bundle that is embedded in a non-ferromagnetic matrix material. The matrix material is doped with marker particles. The peripheral section comprises at least one undoped, non-ferromagnetic matrix material. The diameter of the central section is less than or equal to 0.2 mm, preferably less than or equal to 0.15 mm, and even more preferably, less than or equal to 0.1 mm, and in particular less than or equal to 0.08 mm.Type: GrantFiled: April 23, 2015Date of Patent: September 1, 2020Assignee: MARVIS INTERVENTIONAL GMBHInventors: Klaus Düring, Nasib Dlaikan-Campos, Maarten Van Dijk
