1. A dispensing device to deliver a multiple component material to a location in vivo, the device comprising:
a manifold having a proximal end and a distal end and multiple separate lumens within said manifold, connectable on the proximal end of the manifold to multiple syringes for containing the multiple component material;
a distal tip assembly comprising a tip connector having separate side-by-side lumens within the tip connector and an external thread at a distal end of the tip connector for connecting a threaded dispensing tip;
multiple flexible side-by-side cannulae, each cannula of the cannulae having a proximal end and a distal end, the proximal end of each cannula of the cannulae each connected to a separate lumen of the multiple separate lumens at the distal end of said manifold, and the distal end of each cannula of the cannulae each connected to one of the side-by-side lumens of said tip connector, establishing a fluid communication between said manifold and said distal tip assembly, wherein said side-by-side cannulae are optionally partially connected along a length and are split at the proximal end of each cannula of the cannulae and the distal end of each cannula of the cannulae; and
a rigid tube through which the side-by-side cannulae extend, the rigid tube extending between the distal tip assembly and a housing enclosing at least a portion of the manifold;
wherein the distal end of each cannula of the cannulae is retained within the side-by-side lumens of the tip connector with an adhesive or by overmolding the cannulae in the side-by-side lumens.
