Abstract

A system for dispensing an adhesive comprises a first dispenser, a second dispenser, and a conduit. The first dispenser contains an adhesive. The second dispenser comprises a fluid. The first dispenser and second dispenser are each in fluid communication with the conduit. The conduit has an opening. One or both of the first dispenser or the second dispenser is operable to dispense adhesive or fluid through the opening of the conduit. The system may be used to apply adhesive to the tissue of a patient in a precise and controlled manner.

Claims

1. A method of applying an adhesive to the tissue of a patient during a surgical procedure, the method comprising:

(a) providing an adhesive dispensing system, wherein the adhesive dispensing system comprises;

(i) a first dispenser containing a biosurgical adhesive, wherein the adhesive comprises one of cyanoacrylate or isocyanate;

(ii) a second dispenser containing a fluid immiscible with said adhesive, said fluid comprising a drug, sclerosing agent, necrosing agent, coagulant, ablation agent, image enhancing agents, sealants, radiopharmaceutical, or combinations thereof, wherein said fluid is of a different color than said biosurgical adhesive;

(iii) a conduit comprising a substantially transparent, flexible tube, wherein each of the first dispenser and the second dispenser is in fluid communication with the conduit, wherein the conduit comprises an opening, wherein the one or both of the first dispenser or second dispenser is operable to dispense adhesive or fluid through the opening of the conduit;

(b) using the first dispenser to dispense an amount of adhesive into the conduit;

(c) using the second dispenser to dispense an amount of fluid into the conduit, wherein the dispensed fluid is urged against the dispensed adhesive;

(d) using the dispensed fluid to urge the dispensed adhesive through the conduit; and

(e) applying the dispensed adhesive to the tissue of the patient during the surgical procedure.
