  • Patent number: 8862222
    Abstract: There is described a method for non-invasively measuring electrical activity in a joint of a subject, the method comprising: removably attaching in a non-invasive manner at least two electrodes to a skin surface around an articulation comprising the joint; generating electroarthrographic potentials within the joint by loading the articulation; capturing the electroarthrographic potentials using the at least two electrodes; discriminating between electroarthrographic potentials originating from joint tissue activity and those from other sources; and generating measurement signals representing the electrical activity of joint tissue.

  • Publication number: 20090202430
    Abstract: The present invention provides compositions and methods for tissue repair using a cytocompatible self-gelling cross-linked hydrogel. The composition comprises a biocompatible mixture of chitosan, bifunctional dialdehyde, and hydroxylated polymer, which can be used to immobilize or encapsulate viable cells, or bioactive substances. The method includes the process of mixing bioactive substances, live cells, and/or extracellular matrix components with a cross-linking solution comprising a bifunctional aldehyde-treated hydroxylated polymer such as hydroxyethyl cellulose. The cross-linking solution is then mixed homogenously with a neutral isotonic chitosan solution. The chitosan becomes cross-linked by the bifunctional aldehyde, while the cells are protected from potentially nocive effects of the aldehyde cross-linker by the hydroxylated polymer. The injectable solution retains cell viability and bioactivity, and immobilizes cells at the site of injection or delivery.

  • Publication number: 20070037737
    Abstract: The present invention relates to a new method for repairing human or animal tissues such as cartilage, meniscus, ligament, tendon, bone, skin, cornea, periodontal tissues, abscesses, resected tumors, and ulcers. The method comprises the step of introducing into the tissue a temperature-dependent polymer gel composition such that the composition adhere to the tissue and promote support for cell proliferation for repairing the tissue. Other than a polymer, the composition preferably comprises a blood component such as whole blood, processed blood, venous blood, arterial blood, blood from bone, blood from bone-marrow, bone marrow, umbilical cord blood, placenta blood, erythrocytes, leukocytes, monocytes, platelets, fibrinogen, thrombin and platelet rich plasma. The present invention also relates to a new composition to be used with the method of the present invention.

  • Patent number: 6998960
    Abstract: A method for signaling an escape route in a building with emergency warning units arranged in a distributed way can be realized such that the emergency warning units are equipped with luminous means that in the event of an emergency can be activated by a central emergency warning system sequentially in the manner of a running light that designates the direction of the escape route leading away from a hazard site. An emergency warning unit suitable for this purpose may include two LEDs configured as arrows facing in opposite directions, of which either can be switched into a blinking mode by the central emergency warning system in accordance with the emergency conditions.
