  • Patent number: 6352704
    Abstract: A sterile or non-sterile flavored monomeric adhesive composition includes a flavoring additive and a monomer. The composition can be applied, for example, to skin or the inside of the mouth. A method of making a sterile, flavored adhesive composition includes placing a mixture of a polymerizable adhesive monomer and a flavoring additive in a container, sealing the container, and sterilizing the mixture and the container.

  • Patent number: 6306243
    Abstract: The pH-modified monomer and polymer compositions are useful as biomedical and surgical adhesives, sealants, implants and bioactive agent release carriers or matrices. They comprise a monomer or polymer; and an effective amount of an acidic or basic pH modifier effective to modify the pH of an immediate in vivo environment of the composition to a pH range at which the polymer biodegrades at a different rate than at physiologic pH. The invention also relates to in vivo applications in which surfaces are joined or treated with such pH-modified biocompatible compositions.

  • Patent number: 6283933
    Abstract: A disposable applicator includes a generally tubular applicator body having a closed proximal end and an open distal end and a frangible vial inside. The proximal end is covered by a drying swab while the distal end is covered by an applicator swab that is in open communication with the interior of the applicator body. Within the applicator body is a frangible vial containing a biomedically useful liquid composition, such as an &agr;-cyanoacrylate adhesive, a medicament, or both. The applicator is useful for applying liquid compositions to target sites such as tissue, particularly sites of topical pathology, such as stomatitis lesions.
