    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.

    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: A light activated collagen-flavin composite layer incorporating riboflavin is applied as treatment for infected lesions caused by bacteria and as the consequence of surgical procedures.

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).
