  • Patent number: 9216388
    Abstract: A simulator device configured to replace a filtration unit in a crossflow filtration system comprises a feed inlet (41), a first flow path (43) connected to the feed inlet (41) for simulating a retentate flow in the filtration unit, and a second flow path (44) connected to the feed inlet (for simulating a permeate flow in the filtration unit. Adjustable valve means (45, 46) are provided for controlling at least one of the simulated retentate flow and the simulated permeate flow.
    Type: Grant

  • Patent number: 8419716
    Abstract: A tissue stimulating device that provides a biological stimulation of tissue has a release surface adapted for arrangement adjacent to a tissue to be stimulated. An agent reservoir of the device includes an ionic agent capable of causing a stimulation if present at sufficient high extracellular concentration close to the tissue. An agent releaser is provided in the device for releasing a selected amount of the ionic agent from the agent reservoir to an outside of the release surface at a stimulation occasion for stimulating the tissue. The ionic agent will cause a temporary change in ion permeability of the tissue cell membranes and a depolarization of the tissue cells.

  • Patent number: 8224457
    Abstract: A medical implantable lead has a proximal end and a distal end, and a flexible flat elongate body. The elongate body includes a layer of strip conductors extending along the length of the flat elongate body, a top insulating layer, and a bottom insulating layer. The layer of strip conductors is sealingly enclosed between the top and bottom insulating layers, and at least a major portion of the flat elongate body is twisted into an elongate helical portion having a central cavity extending longitudinally of the helical portion.

  • Patent number: 7945328
    Abstract: A strain reliever for a lead of an implantable heart stimulator, the lead including at least one cable having an electric conductor, has a body of electrically conducting material in electric contact with the electric conductor. The body is lockable in a position in electric contact with electric circuitry of the heart stimulator. The body has a fastening arrangement for fastening the proximal end of the cable at the fastening point on the peripheral surface of the body located at a distance from the distal end of the body. A fixing arrangement is provided at the distal end of the body for fixing the cable to extend in the distal direction from a departure point at the body distal end. The cable is intended to extend in a helical path on the peripheral surface of the body between the fastening point and the departure point.

  • Publication number: 20100280563
    Abstract: In an implantable medical device and a method for treating cardiac tissue of a heart of a patient with therapeutic light, a myocardial infarction is detected and a location the myocardial infarction is identified. A therapy session is initiated by selectively activating one or more of a number of light emitting units arranged in at least one medical lead connectable to the implantable medical device, to emit therapeutic light toward the detected location of the myocardial infarction upon detection of an occurrence of the myocardial infarction.

  • Publication number: 20100168806
    Abstract: For treatment of cardiac tissue of a heart of a patient with therapeutic light using an implantable medical device connectable to at least one medical lead carrying electrodes and at least one fixation element that fixes the lead at a fixation area of the cardiac tissue, therapeutic light is emitted toward the at least one fixation area of cardiac tissue and/or toward a contact area between the at least one electrode and cardiac tissue using an intracorporeal light emitter.
