    Abstract: An improved vaginal speculum for photodynamic therapy of intraepithelial tissue and in particular vaginal, cervical and vulvar neoplasia utilizes a precisely and accurately positionable optic fiber through which a predetermined dose of light in the range of 620 to 700 nanometers is delivered over a controlled area which has been previously treated with photodynamic therapeutic substances. In particular, the neoplastic area has been treated with hematoporphyrin derivatives and other photosensitizers which are selectively taken into the cancerous tissue. Exposure to the appropriate wavelength laser light photoactivates the absorbed hematoporphyrins causing the release of singlet oxygen which internally oxidizes and ultimately causes cell death. The fiber optic tip from which the laser light is transmitted is precisely positioned within the body cavity at a predetermined distance from the intraepithelial neoplasia in order to obtain the appropriate spot size and location to minimize damage to healthy tissue and maximize damage to the selectively impregnated cancerous tissue.

    Abstract: A method and apparatus is disclosed for the instant intraoperative detection and biopsy of metastatic cancer using fluorescence spectroscopy. A photosensitizing agent selectively retained by cancerous tissue is administered prior to surgery. A fiberoptic probe integrated with a biopsy device illuminates the examined tissue and causes fluorescence which is recorded by a spectrograph and plotted as a spectral curve. The intensity ratio (S1/S2) for the fluorescence from the photosensitizing agent (S1) and autofluorescence (S2) for the examined tissue is compared with the intensity ratio at the same wavelengths for primary tumor and normal tissue. Tissue that displays an intensity ratio different from that of normal tissue can immediately be analyzed for the depth of tumor involvement and then excised for histological examination using the biopsy device.

    Abstract: A system is described for the delivery of light to, and/or the receiving of light from, a target located on the wall of a tortuous tube such as a blood vessel. The delivery system is generally useful for laterally delivering and receiving light for the detection and photodynamic therapy of target tissue and is particularly useful for the treatment of atherosclerosis. When certain biocompatible photoreactive molecules such as hematoporphyrin or the like are injected into a patient the molecules are selectively taken up by target tissue such as tumors or atheromatous plaque. Subsequent illumination of the target tissue activates the photoreactive molecules causing fluorescence emission from, and destruction of, the host target tissue. The preferred embodiments comprise a hollow optical waveguide terminating in a supple diffuser tip which may be inserted over an intravascular flexible guide wire. The optical delivery catheter is advanced along the guidewire until the diffuser tip reaches the target tissue. Light of a wavelength suitable to activate previously injected photoreactive molecules is delivered to the target causing selective cell lysis and/or target tissue destruction. The disclosed system is also capable of delivering laser energy for simultaneous hyperthermic generation and photodynamic therapy.
