A catheter (40) for accessing a body cavity such as the reproductive system of the female, the catheter (40) including a shaft (42) which is connected at its distal end to a nonexpansible segment (44). A lumen in the shaft communicates with a passage in the segment. The segment (44) further includes reinforcing material disposed within the segment (44) to resist constriction of the passage. A catheter system and methods of using same includes such an access catheter and an introducing catheter (10) through which the access catheter (40) is insertable, and a transfer catheter (60) which is insertable through the access catheter (40). The invention is useful particularly in treatment of infertility by placing reproductive cells in the uterus or a fallopian tube. <IMAGE> |
