    摘要： A hand-held applicator delivers liquid or semi-liquid compositions, such as adhesives, to an internal tissue or organ in an even and controlled manner. The applicator includes a pump, a tubular extension that is thin enough to pass through an endoscopic pathway or trocar, a proximal end of the tubular extension being sealingly connected to the pump, and an applicator tip that attaches to the distal end of the tubular extension. The tip includes the liquid and the pump pumps the liquid to the internal tissue in an even and controlled manner without contact of the liquid by the pump. The pump is preferably a micropipetter that includes a hand-held portion having a hand-actuatable plunger that does not come in direct, physical contact with the liquid to be dispensed. The composition may be an adhesive such as an alpha-cyanoacrylate. The device may further include a wound closure device including at least two closure pins extending from the distal end of the tubular extension. The wound closure device retracts from the applicator device and orients and aligns a wound or incision target tissue site immediately prior to application of the medical composition. The device provides improved control, ergonomics, and convenience. The device is particularly useful in the field of surgery, especially in the field of laparoscopic or endoscopic surgery, where an even and controlled amount of a medically-acceptable adhesive is to be applied to a target site on an internal tissue or organ.

    摘要： A single-use applicator assembly for dispensing and applying a polymerizable monomeric adhesive material includes: a base portion having at least one sealed compartment; a polymerizable monomeric adhesive material contained in the compartment; an applicator at least partially disposed in the compartment such that a tip of the applicator is proximate the adhesive material. The at least one sealed compartment may comprise first and second sealed compartments that are separated with the polymerizable monomeric adhesive material contained in the first compartment and the applicator at least partially disposed in the second compartment. Alternatively, the first and second compartments may be open to each other. In such case, the applicator assembly may further comprise a plunger that defines the second compartment and that is movable into the first compartment to displace the adhesive material into the second compartment. A kit can include multiple applicator assemblies that are separate or frangibly connected.
