  • Patent number: 6802822
    Abstract: A dispensing tip for e.g. a syringe dispensing an adhesive tissue sealant, having two rigid sections connected together by a flexible section. Preferably, although bendable, the flexible section has enough resilience that in the absence of external force the two rigid sections are held at a predictable angle to one another. In this way manual dispensing into hard to reach places during surgery is facilitated. This flexibility also facilitates use of the dispensing tip with a cannula.

  • Patent number: 6709716
    Abstract: A method for making a bicontinuous, conductive, pressure sensitive adhesive (PSA), such that the starting microemulsion has a convenient viscosity for coating, and such that only a single polmerization step is needed. This has been accomplished by the discovery of a class of thickening agents having a carboxylic acid functionality that are compatible with the microemulsion and yet do not damage the properties of the final adhesive.

  • Patent number: 6708050
    Abstract: The present invention provides a power source for biomedical electrodes and other electronic devices comprising a galvanic cell in a state of partial construction. The galvanic cell generally comprises an anode conductor, a cathode conductor and electrolyte-containing substance. The anode is in electrical contact with a first quantity of electrically conductive medium and the cathode is in electrical contact with a second quantity of electrically conductive medium. The electrolyte-containing substance is separated from at least one of the anode or cathode until the cell is activated by allowing the electrolyte-containing substance to contact the anode and the cathode. Use of the galvanic cell in a drug delivery device is also disclosed.

  • Patent number: 6638144
    Abstract: A method of polishing and cleaning a glass surface with a single abrasive article. The abrasive article includes ceria abrasive particles dispersed in binder, the abrasive article having a textured, three-dimensional abrasive coating. The method includes contacting the glass surface with the abrasive article at a desired pressure and in the presence of water, and moving the abrasive article and glass in relation to each other under pressure. The water is believed to mediate a chemical reaction involving the ceria and the glass, thereby leaving a haze on the glass surface. With continued motion of the abrasive article in relation to the glass workpiece, without the addition of additional water, the haze is removed.

  • Patent number: 6623664
    Abstract: The conductive adhesive of the present invention has a multi-layer structure comprising a hydrophobic phase containing an adhesive polymer, and a hydrophilic phase containing an electrolyte. This conductive adhesive is superior in anti-drying effect (moisturizing effect) because a humectant is effectively contained in the hydrophilic phase. The present invention also relates to a biomedical electrode using such a conductive adhesive. In the biomedical electrode according to the present invention, an adhesive layer to be applied to the skin surface of the human body contains the conductive adhesive described above and an electrode terminal connected with the adhesive layer is provided.
