A method for dispensing a bilogical sealant and a dispensing system for dispensing the biological sealant are described. The dispensing system comprises a dispenser and a plurality of cartridge for delivering a biological sealant to an application site. The sealant is presented as a multi-component liquid sealant, with each component contained in a cartridge comprising a tubular body closed at one end with a pierceable seal and closed at the other end by a piston element movable axially within the tubular body. The dispenser coprises a plurality of recesses to receive respective cartridges containing the components of the sealant. Each recess includes means to establish a fluid connection with the cartridge placed within the recess. The dispenser further comprises means for engaging the piston elements of the cartridges to move the piston element axially so as to expel the sealant components. Ducting within the dispenser leads the sealant components to a dispensing point.
