    • One aspect of the invention relates to an apparatus which has a light emitting portion for directing light radiation from the apparatus onto the lining of a body cavity for treating an ailment in a body cavity of a patient. For example, the ailment may be a gastrointestinal ailment of a patient, such as gastritis, gastric ulcer, duodenal ulcer, gastric cancer, gastric lymphoma, ulcerative colitis, or Crohn's disease. The apparatus may also be used for treating diseases of the circulatory system, urogenital systems and other body cavities. In one embodiment, the apparatus is inserted into a body cavity, e.g., stomach or colon, of the patient to place the distal tip of the apparatus in the desired position. A balloon is then inflated around the light-emitting portion of the apparatus, e.g., an array of optical fiber ends. The body cavity of the patient is then irradiated with light radiation so as to kill or debilitate microorganisms lining the body cavity without significant destruction of the body tissue of the patient, thereby improving or alleviating one or more of the symptoms associated with the ailment. Following treatment, a probiotic may be administered to the patient to reestablish the growth of normal microbial flora after treatment of the gastrointestinal tract.
    • 本发明的一个方面涉及一种设备,其具有用于将来自设备的光辐射引导到体腔的衬里上用于治疗患者体腔中的疾病的发光部分。 例如,疾病可以是患者的胃肠疾病,例如胃炎,胃溃疡,十二指肠溃疡,胃癌,胃淋巴瘤,溃疡性结肠炎或克罗恩氏病。 该装置也可用于治疗循环系统疾病,泌尿生殖系统和其他体腔疾病。 在一个实施例中,该设备被插入到患者的体腔(例如胃或结肠)中,以将该设备的远端放置在期望的位置。 然后在装置的发光部分(例如光纤端部阵列)周围充气。 然后用光辐射照射患者的体腔,从而杀死或减弱衬在体腔内的微生物而不显着破坏患者的身体组织,从而改善或减轻与疾病相关的一种或多种症状。 在治疗之后,可以给患者施用益生菌以在治疗胃肠道后重建正常微生物菌群的生长。
