There is described a dispensing system comprising 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 an openable seal and closed at the other end by a piston element movable axially within the tubular body. The dispenser comprises a plurality of recesses to receive respective cartridges containing the components of the sealant. Each recess has means to establish fluid connection with the interior of the cartridge. The dispenser further comprises means for engaging the piston elements of the cartridges to move the piston elements axially so as to expel the sealant components. Ducting within the dispenser leads the sealant components to a dispensing point. There is further described a method of dispensing the sealant wherein in an initial dispensing step a number of the components of the sealant are delivered, and in a second dispensing step the remaining component or components of the sealant are delivered. Alternatively, all of the sealant components may be simultaneously delivered by loading all of the cartridges into the dispenser at one time.
An apparatus for dispensing a multi-component biological sealant, comprising a plurality of sealant cartridges for containing respective components of the sealant;
An apparatus according to any preceding claim, wherein the drive plate has an elongate guide element receivable in a guide recess in the main body of the dispenser for guiding the movement of the drive plate.
An apparatus according to any preceding claim wherein the means associated with each recess for establishing fluid connection with said one end of a cartridge located in that recess of the dispenser are each independently connected to the dispensing point by a respective duct.
An apparatus according to any preceding claim, wherein the cartridges are formed from transparent material, and windows are formed in the body of the dispenser so that the amount of material present in a cartridge within a recess of the dispenser body may be visually determined.
An apparatus according to any preceding claim wherein the cartridges for respective components of the sealant are of substantially equal axial length, but are of differing cross-sectional area.
An apparatus according to any preceding claim wherein the cartridges are substantially circular in cross-sectional shape.
A dispenser for use in an apparatus for dispensing a multi-component biological sealant each of whose components is contained in a cartridge having a substantially tubular body with a first end closed by an openable seal and a second end sealed by an axially-movable piston element, wherein the dispenser comprises:
A method of dispensing a multi-component biological sealant from a plurality of sealant cartridges containing respective components of the sealant, each sealant cartridge comprising a substantially tubular body having a first end closed by an openable seal and a second end sealed by an axially-movable piston element, the method comprising the steps of:
An apparatus for dispensing a biological sealant substantially as described herein with reference to FIG. 1, FIGS. 2, 3 and 4, FIG. 5, FIGS. 6, 7 and 8, or FIGS. 9 and 10 of the accompanying drawings.
A dispenser for a biological sealant, substantially as herein described with reference to FIGS. 2, 3 and 4, FIG. 5, FIGS. 6, 7 and 8, or FIGS. 9 and 10 of the accompanying drawings.
A cartridge substantially as described herein with reference to FIG. 1 of the accompanying drawings, and containing a component of a biological sealant.
A method of dispensing a biological sealant substantially as described herein.
