    • A waveguide and radiation delivery system is disclosed to be used in topical applications of photodynamic therapy. One preferred embodiment consists of a rectangular waveguide that delivers electromagnetic radiation to a flexible conducting sheet that can be molded to the contours of the treatment sight. The sheet is surrounded by a reflective material or foil, except for the portion of the sheet in contact with the treatment area. That portion is covered with a semi-reflective sheet that is at least translucent with respect to the wavelength used in the treatment. This invention increases the speed and efficiency of the procedure by reducing energy loss due to reflection from the skin surface. It also increases safety by protecting sensitive areas of the body, and is particularly useful for head and neck procedures. Other embodiments include the use of a bladder-type applicator or a rectangular applicator designed to keep the optical fiber a specified distance from the treatment site.
    • 公开了用于光动力疗法的局部应用的波导和辐射递送系统。 一个优选实施例由矩形波导组成,该矩形波导将电磁辐射传递到柔性导电片,该柔性导电片可模制成治疗视线的轮廓。 除了与处理区域接触的片材的部分之外,片材被反射材料或箔包围。 该部分被相对于治疗中使用的波长至少半透明的半反射片覆盖。 本发明通过减少由皮肤表面的反射引起的能量损失来提高手术的速度和效率。 它还通过保护身体的敏感区域来增加安全性,特别适用于头颈部手术。 其他实施例包括使用膀胱型施用器或设计成将光纤保持与处理部位规定距离的矩形施加器。
