1. A device for delivering a flowable composition into a body cavity comprising:

  • an outer cannula comprising an outer cannula wall, an open outer cannula proximal end, an open outer cannula distal end having a size and shape suitable for insertion into a body cavity, an outer cannula lumen extending between the outer cannula proximal end and the outer cannula distal end;

    wherein the outer cannula wall comprises a first outer cannula side-port situated near the outer cannula distal end such that the outer cannula lumen is in fluid communication with the body cavity; and

    an inner cannula insertable into and removable from the outer cannula as well as slidable and rotatable within the outer cannula;

    wherein the inner cannula comprises an inner cannula wall, an open inner cannula proximal end, a closed inner cannula distal end and an inner cannula lumen; and

    wherein the inner cannula wall comprises two or more inner cannula side-ports disposed along the inner cannula longitudinal axis near the inner cannula distal end and disposed around the circumference of the inner cannula such that the inner cannula can be rotatably positioned relative to the outer cannula to align a least one of said inner cannula side-ports with said first outer cannula side-port such that a flowable material can be discharged from within the inner cannula lumen into the body cavity.
