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