Described is a catheter system for implanting embryos into a woman's uterus. The catheter system utilizes a protective catheter sleeve for introducing a catheter into the uterus without mucus contamination of an inner catheter. Once the sleeve containing the inner catheter is introduced into the uterus, the protected inner catheter, carrying the embryos, is pushed through a swivelable distal end cap on the sleeve to a desired implanting location. The distal end of the inner catheter has a protective cap and a side opening for embryo release. Also, stiffness and indicia features of the outer sleeve and inner catheter assist in the physician's handling of the catheter system and in ensuring a desired uterus location for implanting.
