    • Disclosed is a method for modulating wound healing in a mammal. The method includes the steps of: (a) administering a photosensitizer to a mammal that has an unhealed or partially-healed wound; (b) waiting for the photosensitizer to reach an effective tissue concentration at the wound site; (c) photoactivating the photosensitizer by delivering specifically to the wound site light of an effective wavelength and intensity, for an effective length of time. The modulation of wound healing can include hastening healing by administering a low dose of photodynamic therapy. Alternatively, the modulation can include inhibiting fibrosis by administering a high dose of photodynamic therapy. The photosensitizer can be targeted, for example, to macrophages or myofibroblasts. Targeting can be by conjugation to a targeting moiety such as a protein, peptide or microparticle.
    • 公开了一种调节哺乳动物伤口愈合的方法。 该方法包括以下步骤:(a)向具有未愈合或部分愈合的伤口的哺乳动物施用光敏剂; (b)等待光敏剂在伤口部位达到有效的组织浓度; (c)通过在有效的时间长度内特异性地输送有效波长和强度的伤口部位的光来光敏化光敏剂。 伤口愈合的调节可以包括通过施用低剂量的光动力疗法来加速愈合。 或者,调节可以包括通过施用高剂量的光动力疗法来抑制纤维化。 光敏剂可以靶向例如巨噬细胞或肌成纤维细胞。 靶向可以通过与靶向部分如蛋白质,肽或微粒共轭。

    • An integrated optical biopsy forceps device (10) and a method for tissue identification by optical analysis and biopsy sampling at a site within the body. The device includes an elongated catheter body for introduction into the body and navigation to an area of interest. An optical fiber (50) extends through the device, from the proximal end, where it may be connected to electro-optical spectral analysis equipment, to a distal tip for illuminating and receiving light energy from tissue at the location of the tip. The distal end of the device has a pair of cutting jaws (80, 81) pivotally mounted at the distal end of the catheter body and controlled by control wires (40, 41) extending through the catheter body to a control handle at the proximal end, or by the optical fiber. The device may be spectroscopically guided to a site of interest within the body. The fiber tip (50) is positioned coaxially with the jaws at the zone of contact and cutting of the jaws, and is retracted as the jaws close, so that the biopsy sample is taken exactly at the spot being viewed by the optical fiber.
    • 一种综合光学活检钳装置(10)以及通过在体内部位进行光学分析和活组织检查取样的组织鉴别方法。 该装置包括用于引入身体并导航到感兴趣区域的细长导管体。 光纤(50)从近端(其可以连接到电光谱分析设备)延伸穿过该设备到远端,用于照射和接收来自尖端位置处的组织的光能。 装置的远端具有一对可枢转地安装在导管主体的远端处的切割钳口(80,81),并由延伸穿过导管主体的控制线(40,41)控制在近端的控制手柄 ,或通过光纤。 该装置可以被光谱地引导到身体内的感兴趣部位。 纤维尖端(50)在钳口的接触和切割区域处与颚骨同轴地定位,并且随着颚关闭而缩回,使得活检样本准确地在被光纤观察的位置处被拍摄。
