Abstract:
A catheter system for implanting embryos in a uterus, the system comprising:a. a substantially tubular inner catheter comprising a catheter port positioned proximal a rounded distal catheter end; and b. a catheter outer sleeve having a longitudinal cylindrical hollow within the catheter outer sleeve and extending from a sleeve proximal end to a sleeve distal end, the sleeve distal end having a rounded end and a slit in the sleeve distal end extending from an outer surface of the catheter outer sleeve to the cylindrical hollow, the rounded end being hingedly attached to the distal end and normally biased closed against the cylindrical hollow; wherein the slit is located at a first location on the distal end proximal a second location on the distal end, the second location having a second outer sleeve external diameter greater than or equal to a first outer sleeve external diameter of the first location; and wherein the cylindrical hollow is sized and shaped to receive the inner catheter therethrough, thereby providing catheter access to the uterus by the inner catheter pushing open the normally biased closed rounded end at the slit.
