  • Patent number: 8554299
    Abstract: The present invention is concerned with an electrode and electrode catheter using thin metallic threads or wires, for example, microwires having diameters as low as 10?6 to 10?4 meters or less. The embodiments allow for the efficient mounting of at least one electrode on a catheter, resulting in the creation of a flexible ring-microelectrode that is suitable for, amongst other things, the detection of myoelectrical activity in a patient's muscle, such as the diaphragm or other inspiratory-related muscle.
    Type: Grant
    Filed: May 17, 2012
    Date of Patent: October 8, 2013
    Assignee: Maquet Critical Care AB
    Inventors: Christer Sinderby, Norm Comtois, Göran Rydgren, Tord Lindner

  • Patent number: 7735488
    Abstract: A medical device has a cuff adapted to be positioned in the trachea of a subject with a patient tube, and a first tube having a distal end coupled to the cuff and a proximal end communicable with the surroundings. More effective and simpler sample taking and/or dosing of medicament is achieved by a second tube that is coupled with a distal end to the cuff and communicable with the surroundings via a proximal end, together with a pumping device that is connected to the proximal end of the first tube and to the proximal end of the second tube in order to circulate a fluid through the cuff. The cuff has a membrane that is permeable to a specific substance, the membrane being disposed to allow transfer of the specific substance between the interior and the exterior of the cuff.

  • Patent number: 7266403
    Abstract: In a method and device for preparation of a medicament for the treatment of lungs having a surfactant deficiency, a sample from a patient is quantitatively analyzed with regard to at least one of the proteins SP-A, SP-B, SP-C and SP-D, a determination is made as to whether a deficiency of one of the analyzed protein SP-A, SP-B, SP-C or SP-D exists and if that is the case, a determination is made of a therapeutically effective dose of a replacement substance for the analyzed protein SP-A, SP-B, SP-C or SP-D, and a medicament containing the therapeutically effective dose of the replacement substance is prepared.
