Patent number: 11707212Abstract: The present disclosure relates to a dialysis device (1), more particularly a microdialysis device for the sampling of substances from the surface of a body organ. The device is particularly useful in the context of the monitoring of a moving organ, such as a beating heart, as the device comprises attachment means (2) allowing for a flexible and reliable attachment thereto. Furthermore, the microdialysis device provides for an efficient exchange of substances, such as metabolic substances, between the organ and the dialysis fluid through a semi-permeable material forming part of the device. There is also provided a method encompassing the device of the disclosure.Type: GrantFiled: January 8, 2021Date of Patent: July 25, 2023Assignee: SENZIME AB (PUBL.)Inventors: Pernilla Abrahamsson, Robert Herz, Einar Pontén, Bjoern Glaesel

Patent number: 8521248Abstract: In a fiber-optic probe for intravascular measurements, e.g. oxygen saturation measurements, the fiber-optical core has only two fibers. A single fiber core is also possible. A reinforcement fiber improves stiffness, kink resistance and overall strength of the probe. The reinforcement fiber is arranged essentially parallel to the core fibers. The reinforcement fiber may also be wound around the core in a helical manner thus improving the mechanical properties to an even higher degree. The outside of the sheath is coated with an antithrombogenic coating for reducing the danger of clots forming at the surface. The reinforcement fiber may be made of carbon, metal, ceramics or aramide.Type: GrantFiled: August 19, 2009Date of Patent: August 27, 2013Assignee: PULSION Medical Systems SEInventors: Marcus Veeck, Oliver Goedje, Robert Herz, Thomas Thalmeier, Christoph Manegold, Matthias Bohn

Publication number: 20110238020Abstract: The invention relates to a catheter device with an integrated fiber optic, in particular for use in thermodilution measurement and pulse contour analysis. The device comprises an arterial catheter (2) with a suitable intravascular part and a suitable extravascular part and an optical sensor unit for combined pressure and temperature measurement at a measurement location at the distal end of the suitable intravascular part or proximate to the distal end of the proper intravascular part of the catheter (2). The optical sensor unit comprises a fiber optic conductor (11) that runs from the measurement location to a proximal port.Type: ApplicationFiled: September 2, 2009Publication date: September 29, 2011Applicant: PULSION Medical systems AGInventors: Oliver Goedje, Marcus Veeck, Robert Herz, Matthias Bohn, Stephan Joeken

Publication number: 20080077043Abstract: The catheter has a proximal port with an opening of a feeding lumen. There are two further openings in another proximal port with a connector, to which a source/sink of gas pressure and a pressure gauge can be connected. The interior of a distal balloon communicates with the opening and can hence be inflated and deflated through that opening in order to measure intra-abdominal pressure using the pressure gauge. A reflux filter is integrated into the connector. In the upper connector piece or lower connector piece a recess surrounding the measurement lumen is provided at the contact surface between the connector pieces. The gas-permeable filter membrane is disposed in the recess for preventing liquids in the lumen from entering from the lower connector piece into the upper connector piece and thus from passing through the opening in case of rupture or leakage of the distal balloon.Type: ApplicationFiled: August 20, 2007Publication date: March 27, 2008Inventors: Manu Malbrain, Robert Herz, Matthias Bohn, Oliver Goedje

Publication number: 20050187532Abstract: A reservoir (10, 26, 80, 126, 226, 380) includes a rigid wall (12, 28, 82, 128, 228, 382), a flexible membrane (14, 34, 134, 234, 334) sealingly secured to the rigid wall (12, 28, 82, 128, 228, 382) to define a variable volume chamber (18, 38, 138, 238, 338), and inlet (40, 140, 240, 340) and exit (42, 142, 242, 342) ports in fluid communication with the chamber (18, 38, 138, 238, 338). A drive surface (24, 50, 150, 250, 350) engages the membrane (14, 34, 134, 234, 334) to position it adjacent the rigid wall (12, 28, 82, 128, 228, 382) to define a minimum volume position. The drive surface (24, 50, 150, 250, 350) may be moved so that the membrane (14, 34, 134, 234, 334) flexes out of the minimum volume position to an expanded volume position. The membrane (14, 34, 134, 234, 334) may be coupled to the drive surface (24, 50, 150, 250, 350) or be uncoupled from the drive surface (24, 50, 150, 250, 350).Type: ApplicationFiled: February 24, 2004Publication date: August 25, 2005Applicant: Medex, Inc.Inventors: Bernd Thurau, Robert Herz, Angela Crall, Dale Gallogly

Patent number: 5779892Abstract: A magnetic separator device is provided for separating biological materials from carrier fluids using the technique of high gradient magnetic separation. A release compensator reduces the amount of force that an operator needs to apply in order to remove a separation column from the magnetic field of the separator device. The release compensator may be a mechanical compensator, but is preferably a magnetic compensator. The magnetic separator device also preferably includes a mount for mounting the device to a wall. The mount is preferably a pair of additional magnets.Type: GrantFiled: November 15, 1996Date of Patent: July 14, 1998Assignee: Miltenyi Biotec GmbHInventors: Stefan Miltenyi, Gerard Buchholz, Robert Herz
