A delivery device includes a housing, an ultrasound converter within and supported by the housing and an ultrasound horn coupled to the ultrasound converter and extending through an opening in the housing. The device may also include a first mating surface adjacent the opening, a cup assembly having an upper surface and a lower surface and a generally cylindrical interior portion extending between an opening in the upper surface and an opening in the lower surface. Additionally, the device may include a second mating surface adjacent the cup assembly upper surface, wherein when the first mating surface is coupled to the second mating surface a distal most portion of the ultrasound horn is disposed within the generally cylindrical interior portion without contacting the cup assembly.
