Karl-Heinz Koelker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7993284
    Abstract: A system is provided for withdrawing small amounts of body fluid from an animal or human. The system includes a holder and a disposable lancing unit attached to the holder. The lancing unit also includes an open capillary channel for transporting the body fluid and piercing the skin.
    Type: Grant
    Filed: September 20, 2007
    Date of Patent: August 9, 2011
    Assignee: Roche Diagnostics Operations, Inc.
    Inventors: Carlo Effenhauser, Heinz-Michael Hein, Karl-Heinz Koelker, Frank Deck
  • Patent number: 7682430
    Abstract: The invention concerns a device which is used to separate gas or liquid from microfluidic flow-through systems. The gas or liquid separation is achieved independently of the spatial orientation of the device. In addition the invention concerns a microfluidic flow-through system in which a device according to the invention enables bubble-free fluid transport.

  • Patent number: 7156118
    Abstract: The invention relates to the technical field of microfluidic channel structures. The invention discloses a microfluidic channel system with a high aspect ratio as well as a process for producing the microfluidic system. The process according to the invention enables the production of channel structures with aspect ratios of any magnitude without the process being limited by the manufacturing conditions to certain materials for the channel system. The channel system can thus be optimally adapted to a desired field of application.
