APPLICATORS FOR STORING STERILIZING, AND DISPENSING AN ADHESIVE
First Claim
Patent Images
1. An applicator for storing and dispensing an adhesive comprising:
- a) a container comprising walls defining a chamber having an opening at the distal end and fabricated from a material that is substantially impermeable to moisture and air, a distal seal, a middle seal, and a proximal seal, and a polymerizable cyanoacrylate monomer adhesive stored in the chamber between the proximal seal and the proximal end of the container;
b) a body comprising a flange comprising at least one hole, a channel in communication with the hole, extending distally through the body, and having an opening at the distal end, and optionally, a grip capable of constricting the channel when inward pressure is applied to the grip, wherein the proximal end of the flange is positioned between the middle seal and the proximal seal of the container and is capable of penetrating the proximal seal when the body and the container are compressed together;
c) a porous tip in communication with the opening at the distal end of the channel; and
d) optionally, a removable lock between the container and the body that prevents the body and the container from being compressed together and that when removed allows the body and the container to be compressed together;
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.

Abstract
Applicators for storing, sterilizing, and dispensing adhesives are provided. The applicators comprise a porous tip, a body, and a container containing a polymerizable cyanoacrylate monomer adhesive. The applicators are sterilized by radiation, and following sterilization, the adhesive remains substantially unpolymerized for about twenty four months.

11. An applicator for storing and dispensing an adhesive comprising:
-
a) a flexible handle comprising a housing for containing a removable adhesive container and a female end of a luer lock at the distal end of the handle; b) a body comprising a male end of a luer lock at the proximal end of the body and capable of connecting with the female end at the distal end of the handle, and a channel extending distally through the body, and having an opening at the distal end; c) a porous tip in communication with the opening at the distal end of the channel; and d) a removable adhesive container fabricated from a material that is substantially impermeable to moisture and air and capable of fitting within the housing, comprising a frangible seal at the distal end of the container, and a polymerizable cyanoacrylate monomer adhesive stored in the container; wherein the applicator is activated by compromising the frangible seal whereupon the adhesive may flow into and through the channel and out of the porous tip. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. An applicator for storing and dispensing an adhesive comprising:
-
a) a container comprising walls defining a chamber having an opening at the distal end and fabricated from a material that is substantially impermeable to moisture and air, a frangible seal covering the opening, a polymerizable cyanoacrylate monomer adhesive stored in the chamber, and optionally, screw threads on the exterior of the walls; b) a body comprising a cavity at the proximal end, a channel in communication with the cavity, extending distally through the body, and having an opening at the distal end, a grip capable of constricting the channel when inward pressure is applied to the grip, at least one projection in the cavity, wherein the projection is capable of penetrating the frangible seal when the body and the container are compressed together, and optionally, screw threads on the walls of the cavity; c) a porous tip in communication with the opening at the distal end of the channel; and d) optionally, a removable lock between the container and the body that prevents the body and the container from being compressed together and that when removed allows the body and the container to be compressed together; wherein the applicator is activated by compressing the body and the container together whereupon the projection penetrates the frangible seal and allows the adhesive to flow into and through the channel and out of the porous tip. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
