Abstract:
1. A delivery system comprising an injector system coupled to a driving system, the injector system comprising: a housing defining a lumen and having an output end and a driving system connection end, the lumen comprising a proximal portion and a distal portion and the inner diameter of the proximal portion being substantially larger than the inner diameter of the distal portion; a needle assembly coupled to the output end of the housing; an elongated helical element extending through the lumen from the driving system connection end to at least a portion of the needle assembly, the elongated helical element defining a mixing member being rotatable within the lumen in both the proximal portion and the distal portion, wherein the elongated helical element extends through the output end and through the driving system connection end; and the driving system comprises: a drive mechanism; an actuator coupled to the drive mechanism to actuate the drive mechanism; and a rotatable interfacing member coupled to the drive mechanism for coupling with the mixing member to rotate the mixing member when the interfacing member is driven by the drive mechanism, wherein the mixing member is rotatable in the needle assembly and wherein mixing occurs in the needle assembly.
