There is disclosed an arrangement for applying a tissue adhesive based on human or animal proteins to seamlessly or seam-supportingly connect human or animal tissue or organ parts, to seal wounds, stop bleedings and the like. The tissue adhesive is formed in situ by combining solutions of the proteins and of blood-clot-promoting coagulation factors. The arrangement includes a plurality of containers ending in joining pieces for accommodating the components to be applied. A connecting head is attachable to the joining pieces of the containers, which includes a separate conveying channel for each of the components to be applied. In order to design an arrangement of the above defined kind to be troublefree and to render it usable even for hardly accessible application sites, without requiring an exchange of parts of the arrangement at an interruption of the component flow, and to be able to use it with and without the help of an endoscope, the connecting head includes an additional conveying channel for a medicinal gas. This channel leads to the front side of the connecting head parallel and closely adjacent the remaining conveying channels. The connecting head is continued in either a multi-lumen catheter containing a gas-conveying channel or in a mixing needle.

In an apparatus for applying a tissue adhesive based on human or animal proteins to be used for seamlessly or seam-supportingly connecting human or animal tissue or organ parts, for sealing wounds, stopping bleedings and the like, said tissue adhesive being formed in situ by bringing together at least two components comprised of solutions of said proteins and blood clot-promoting coagulation factors, said apparatus comprising a plurality of disposable syringe bodies made of synthetic material and adapted to contain said components, said bodies including coni through which the components are to be expelled, a connecting head attachable to said coni, and separate component-conveying channels disposed in said connecting head for conducting said components to be applied, the improvement wherein a gas-conveying channel is provided in said connecting head for conducting a medicinal gas, said gas-conveying channel extending to a front side of said connecting head to discharge gas in a direction parallel to the discharge of said components from said component-conveying channels and closely adjacent thereto, a multi-lumen catheter formed of one-piece integral construction with said connecting head and including a plurality of component-conveying lumina communicating with respective ones of said component conveying channels, and a gas-conveying lumen communicating with said gas-conveying channel, whereby said syringes can be removed from said connecting head and integral catheter for replacement.
