A cannula assembly comprising: a cannula having a proximal end, a distal end opposite the proximal end, and a lumen extending from the proximal end to the distal end along a longitudinal axis, the lumen configured to receive a surgical instrument therein, the cannula comprising: a generally tubular cannula body having an exterior surface and a first outer diameter; and an annular recess formed in the exterior surface of the cannula body adjacent the distal end of the cannula, the annular recess transverse to the longitudinal axis, the annular recess having a second outer diameter smaller than the first outer diameter of the cannula body, and the annular recess having a textured surface adapted to receive an adhesive; and a sleeve having a proximal end and a distal end, the sleeve disposed around the cannula from adjacent the proximal end of the cannula to the annular recess, the sleeve comprising: an elongate tubular body; and a balloon positioned distal the elongate tubular body; wherein the annular recess extends along the cannula a first length relative to the longitudinal axis; and the sleeve comprises a bonding segment distal the balloon, the bonding segment extending into the recess a second length relative to the longitudinal axis, the second length less than the first length. a cannula having a proximal end, a distal end opposite the proximal end, and a lumen extending from the proximal end to the distal end along a longitudinal axis, the lumen configured to receive a surgical instrument therein, the cannula comprising: a generally tubular cannula body having an exterior surface and a first outer diameter; and an annular recess formed in the exterior surface of the cannula body adjacent the distal end of the cannula, the annular recess transverse to the longitudinal axis, the annular recess having a second outer diameter smaller than the first outer diameter of the cannula body, and the annular recess having a textured surface adapted to receive an adhesive; and a generally tubular cannula body having an exterior surface and a first outer diameter; and an annular recess formed in the exterior surface of the cannula body adjacent the distal end of the cannula, the annular recess transverse to the longitudinal axis, the annular recess having a second outer diameter smaller than the first outer diameter of the cannula body, and the annular recess having a textured surface adapted to receive an adhesive; and a sleeve having a proximal end and a distal end, the sleeve disposed around the cannula from adjacent the proximal end of the cannula to the annular recess, the sleeve comprising: an elongate tubular body; and a balloon positioned distal the elongate tubular body; wherein the annular recess extends along the cannula a first length relative to the longitudinal axis; and the sleeve comprises a bonding segment distal the balloon, the bonding segment extending into the recess a second length relative to the longitudinal axis, the second length less than the first length. an elongate tubular body; and a balloon positioned distal the elongate tubular body; wherein the annular recess extends along the cannula a first length relative to the longitudinal axis; and the sleeve comprises a bonding segment distal the balloon, the bonding segment extending into the recess a second length relative to the longitudinal axis, the second length less than the first length.
