Abstract:
1. An applicator for storing and dispensing an adhesive comprising: a) a container comprising walls defining a chamber comprising a proximal end and a distal end and an opening at the distal end of the chamber, said walls comprising a single layer of a copolymer of acrylonitrile and methyl acrylate or comprising multiple layers with the inner-most layer comprising a copolymer of acrylonitrile and methyl acrylate, said chamber further comprising a frangible distal seal, a frangible middle seal, and frangible a proximal seal covering the distal end of the chamber, said proximal seal having a side in communication with an adhesive stored in the chamber between the proximal seal and the proximal end of the chamber, said adhesive comprising a cyanoacrylate monomer, a free radical stabilizer in an amount of 200 ppm to 15,000 ppm, and an anionic stabilizer in an amount of about 10 ppm to about 200 ppm; b) a body comprising a proximal end and a distal end, a flange comprising at least one hole, a channel in communication with the hole, said channel extending through the body, and having an opening at the distal end of the body, and a grip capable of constricting the channel when inward pressure is applied to the grip, wherein the proximal end of the body is positioned between the middle frangible seal and the proximal frangible seal of the chamber when the applicator is not activated, and is capable of penetrating the proximal frangible seal when the body and the container are compressed together; and c) a porous tip in communication with the opening at the distal end of the channel; wherein the applicator is activated by compressing the body and the container together whereupon the flange penetrates the proximal seal and allows the adhesive to flow into the hole, through the channel, and out of the porous tip, and wherein at least the container is sterilized by radiation, and the adhesive stored in the container does not cure upon radiation exposure and for at least about twelve months of shelf storage thereafter.
