1. A device for providing a composition comprising gametes or embryos to a uterus of a subject, comprising, a handle; an insertion tube; a composition delivery container comprising a composition delivery container syringe and plunger, a composition delivery catheter having a proximal end and a distal end, wherein the proximal end of the composition delivery catheter is in fluid connection with the composition delivery container and the distal end of the composition delivery catheter is an exit port for entry and exit of the composition; wherein proximal movement of the composition delivery container plunger draws a composition into the exit port, and distal movement of the composition delivery container plunger expels the composition from the exit port; a distension syringe comprising a distension syringe body and a distension syringe plunger having a distension plunger head; a distension catheter, having a proximal end and a distal end, and comprising an enlarged section located proximally to the proximal end of the distension catheter, wherein the enlarged section is contactable by a lever so that downward pressure by the lever compresses the enlarged section and prevents passage of distension media through distension catheter, wherein the proximal end of the distension catheter is in fluid connection with the distension syringe comprising a distension syringe plunger, and the distal end of the distension catheter is in fluid connection with an end structure, wherein adjacently connecting the distension catheter and the composition delivery catheter forms a dual lumen catheter having the exit port and the end structure;, a catheter carrier for moving the dual lumen catheter outwardly from and inwardly toward the insertion tube.
