Abstract: An apparatus to establish access into the uterus and the fallopian tubes of a female for diagnostic or therapeutic procedures includes a cervical access catheter, an ostial access catheter insertable through the cervical access catheter, and a fallopian access catheter insertable through the ostial access catheter. The cervical access catheter incorporates a distally located intrauterine balloon which is inflatable after insertion into the uterus. The cervical access catheter also incorporates a cervical retention disk which can be slid into position against the anterior lip of the cervix to anchor the cervical access catheter into the cervical canal between the intrauterine balloon and the cervical disk. Once the cervical access catheter is properly anchored, the ostial access catheter is inserted through the cervical access catheter.

Abstract: A delivery catheter for introducing living matter into a body passageway or cavity of a female mammal comprises a hollow, flexible, dual lumen catheter having substantially tubular-shaped collection chamber for holding the living matter. An ejection port is formed adjacent to the distal end of the collection chamber and an actuator port is formed at its proximal end. A guide tube having a lumen, is positioned coaxially within the collection chamber with the respective distal and proximal ends of the guide tube and the collection chamber joined together in fluid-tight sealing engagements. In an alternate embodiment, the lumina are separated to create a guide wire lumen which is substantially parallel to a transfer lumen. Also, the distal end of the catheter is beveled to recess the opening of the guide wire lumen from the port of the collection chamber in the transfer lumen. In operation, the delivery catheter is inserted into the body passageway over a prepositioned guide wire.

More specifically, the delivery catheter receives the guide wire through the lumen of its guide tube to advance the delivery catheter along the guide wire.
