Chemical Bonding Material Applied To Wound Edges Patents (Class 606/214)
  • Patent number: 10357591
    Abstract: Otologic materials and methods are provided. For example, a cell-adhesive, biodegradable hydrogel scaffold loaded with time-released drugs for repairing chronic tympanic membrane perforations is disclosed, methods of making same and administering same are provided. This hydrogel may promote vascular in-growth and epithelial cell growth of the tympanic membrane with the purpose of closing the perforation and providing a barrier between the external and middle ear. The hydrogel is initially a liquid polymer that only gels upon exposure to specific conditions, such as exposure to light. This scaffold may simultaneously induce repair of the tympanic membrane while preventing or alleviating middle ear infection, thus filling a void in current tympanic membrane perforation therapies.

The closed incision tissue therapy device also comprises a collection chamber, which may comprise an elongate tubular chamber with a plurality of longitudinally spaced openings. The collection chamber may be configured to be in fluid communication with the sealant layer and the area of skin trauma and functions as to distribute the negative pressure applied to a surgically closed area of skin trauma. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of air molecules under the sealant layer. The collection material may comprise a material and/or a configuration that permits length changes based upon the length of the corresponding surgical wound or incision.

  • Patent number: 9006182
    Abstract: 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 adheives 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.

The tablet improves the rate of adhesion to a bleeding wound surface, and allows a significantly greater and more uniform pressure to be exerted by manual compression of the tablet on the wound site, as compared to that of a thin layer of scattered hemostatic powder. After the seal is formed from the interaction of blood or exudates with the immediate contacting surface of the tablet, the bulk of the unused tablet easily delaminates from the seal making clean up facile. If the unused portion of the tablet is not removed from the wound site, a reservoir of hemostatic dressing stops further bleeding and to provide antimicrobial protection and healing.

  • Patent number: 8876862
    Abstract: A hemostatic device is provided for sealing a puncture of a vessel. The hemostatic device includes a locator device and an injection tube coupled to the locator device. The locator device includes a device valve that is actuatable to selectively restrict access to a portion of the locator device. The hemostatic device is advanced into the vessel until a first fluid is channeled through the locator device. The device valve is actuated to selectively restrict the first fluid from being channeled through the locator device. A second fluid is injected through the injection tube to facilitate sealing a puncture of the vessel. The hemostatic device is withdrawn from the vessel.

  • Patent number: 8876844
    Abstract: An exemplary anastomosis device comprises a proximal ring, a distal ring, and a middle ring. The middle ring has apertures configured to communicate a fluid such as an adhesive. The exemplary anastomosis device also has arms joining the proximal ring to the center member and arms joining the distal ring to the center member. The anastomosis device is configured to move from an unactuated position, where it has a generally cylindraceous configuration, to an actuated position, where it has a generally rivet-like configuration. The anastomosis device may be used to provide and secure an anastomosis between adjacent tissue walls. Adhesive may be communicated through the apertures of the middle ring of the anastomosis device to seal or strengthen the anastomosis. An applier may be used to deploy the anastomosis device and to communicate the adhesive through the apertures.
