    摘要: Methods and devices for delivering therapeutic or diagnostic energy (e.g., light, ultrasound, ionizing radiation (e.g., x-ray), vibration, heat energy, etc.) into the eye. An energy emitting device is positioned on the eye and used to deliver energy into the eye. The device may be constructed to allow the subject's eyelids to open and close while the device is positioned on the eye. The device is useable for various energy based or energy-mediated therapies, including crosslinking of corneal collagen, light therapy, photodynamic therapy, photo-activation of drugs, etc.

    摘要: Consistent with the present invention, a tube is provided that contains both a sensing and a laser delivery fiber to the target area. The length of the tube can be varied to any desired length. The end portion of the tube includes a second piece, which is a cap having two through holes or passages. These holes can be formed by standard machining or micromaching methods. The first hole can accommodate the sensing fiber, while the second hole contains the laser delivery fiber. The first and second holes extend in first and second directions, respectively, and form an angle therebetween such that the sensor fiber viewing area is within the radiation area created by the laser delivery fiber. Accordingly, the sensor fiber receives energy emitted from a central portion of the radiation area so that the temperature of the exposed tissue can be accurately determined.

    摘要: Consistent with the present disclosure a method is provided in which a plurality of surgical meshes are provided, each of which may include a coating that has a chromophore. Alternatively, each mesh has a plurality of rivets or tacks that include the chromophore. The meshes may then be positioned to overlap one another or be provided adjacent one another inside the body cavity such that the mesh cover the wound site. The meshes may then be exposed to light at a wavelength that activates the chromophore and causes the meshes to adhere to one another and the underlying tissue. In one example, the coating or the tacks includes a combination of relatively high concentration derivatized collagen and riboflavin, lumiflavin or lumichrome.

    摘要: A light activated collagen-flavin composite layer incorporating riboflavin is applied as treatment for infected lesions. These composites have also been found to be strong tissue adhesives that are effective in closing and sealing wounds, fixation of grafts/ implants and anastomoses. Advantages include speed of closure, reduced infection due to the elimination of foreign matter, evidence of accelerated wound healing and the ease of use in complex surgery, especially when watertight seals, limited access or small repair size are important factors. The riboflavin in the collagen layer is exposed to light (e.g., light having a wavelength between 360-375 nm or 440-480 nm), decomposing the riboflavin to form reactive oxygen species (ROS). Strong crosslinks between the collagen composite and tissue results. In addition, similar exposures eradicate pathogens in the wound.

    摘要: Consistent with an aspect of the present disclosure, a mesh or other surgical material is wrapped about one or more shafts, and inserted into a body cavity where it is unfurled and placed over a tissue site, such as a hernia. The mesh, for example, is secured to the shaft in order to prevent crimping or crumpling thereof during deployment over the tissue site.

    摘要: Consistent with the present invention, tissue adhesive compositions and an associated laser exposure system are provided for bonding or sealing biological tissues. The compositions are comprised of chemically derivatized soluble collagen which is formulated to concentrations ranging from 300 mg/ml (30%) to 800 mg/ml (80%) collagen protein. In particular, Type I collagen, for example, is first prepared by extraction from bovine or porcine hide and purified. The collagen preparations are then chemically derivatized with sulfhydryl reagents to improve cohesive strength and with secondary derivatizing agents, such as carboxyl groups, to improve the adhesive strength of the solder to the tissue. The compositions are then formed into viscous solutions, gels or solid films, which when exposed to energy generated from an infrared laser, for example, undergo thermally induced phase transitions. Solid or semi-solid protein compositions become less viscous enabling the high concentration protein to penetrate the interstices of treated biological tissue or to fill voids in tissue. As thermal energy is released into the surrounding environment, the protein compositions again become solid or semi-solid, adhering to the treated tissue or tissue space.
