A device for mixing and delivering a curable biomaterial using minimally invasive techniques. The device provides a mixing path that is configured to contribute a longitudinal distance dimension to the device that is considerably less than the length of the mixing path itself. In so doing, the device can provide improved ergonomic control and single-handed operation in the course of mixing biomaterial components, in order to initiate cure, and delivering the mixed biomaterial through a delivery conduit and to a tissue site in vivo. Optional features of the device include the ability to warm the biomaterial components, to position or retract a protective sheath covering the delivery conduit, and the ability to divert or shunt an initial volume of mixed biomaterial.

[ What is claimed is:] [1.] A device for mixing and delivering a curable biomaterial, the device comprising:(a) an attachment site for a biomaterial source, the source comprising a plurality of biomaterial components adapted to be mixed in order to initiate cure,(b) a body portion comprisingi) a handle for gripping and actuating the device, andii) a biomaterial mixing path having inlet and exit ends, the inlet end of the mixing path adapted to be placed in fluid communication with the biomaterial component source, the mixing path being adapted to combine and mix the components within a time suitable to permit the mixed components to traverse the mixing path in a flowable fashion, and within an longitudinal distance adapted to provide controllable, ergonomic operation in the course of minimally invasive surgery, and(c) a delivery unit comprising a deliver conduit having an inlet end in fluid communication with the exit end of the mixing path, and an exit end adapted to deliver the mixed biomaterial to a tissue site,wherein the device is adapted for single-handed operation, and the mixing path provides a longitudinal length dimension to the device that is on the order of one-tenth, or less, the overall length of the mixing path, andfurther comprising a mechanism for controllably shunting an initial portion of mixed biomaterial.
