    • An apparatus and method for detecting infected tissue are disclosed. The apparatus comprises a light source for producing a light beam and an optical element having an input end optically coupled to the light source and an output end arranged to direct the light beam as a confocal beam into tissue. The apparatus also comprise a detector optically coupled to the optical element to receive a return beam back from the tissue stimulated by the confocal beam and to generate an output dependent upon the return beam. An analyser is arranged to analyse the output of the detector to determine whether the return beam is indicative of infected tissue. The use of a confocal beam allows it to be directed to a specific predetermined point or depth in tissue, such as a tooth, thus eliminating the 'swamping effect' of the bulk background tissue. Thus an embodiment of the apparatus is more sensitive at detecting infected tissue.
    • 公开了一种用于检测感染组织的装置和方法。 该装置包括用于产生光束的光源和具有光耦合到光源的输入端的光学元件和布置成将光束作为共焦束引导到组织中的输出端。 该装置还包括光学耦合到光学元件的检测器,以从由共聚焦束刺激的组织接收返回光束并产生取决于返回光束的输出。 分析器被布置成分析检测器的输出以确定返回光束是否指示感染的组织。 使用共焦束允许其被引导到组织(例如牙齿)中的特定预定点或深度,从而消除了散装背景组织的“淹没效应”。 因此,该装置的一个实施例在检测感染的组织时更为敏感。

    • This invention related to a tissue-adhesive sheet comprising a homogeneous, preformed and cross-linked matrix formed from one or more polymers, and having at least one surface that, in use, is exposed, at least one of said one or more polymers being a synthetic polymer and having appendant functional groups of a first form, cross-linking of said matrix being via a proportion of said functional groups of the first form, and the remainder of said functional groups of the first form being free. The sheet is particularly useful as a tissue adhesive and sealant, and is intended for topical application to internal and external surfaces of the body for therapeutic reasons. The invention further relates to sheets comprising a scaffold material, three-dimensional articles formed from similar material to that of the sheet and to implantable medical devices coated with such material.
