ABSTRACT:
The invention is a single use transcervical catheterization cannula retained by forceps for use with a catheter wire and radiopaque dye fluid. The cannula has a flexible shaft portion, an acorn to seat with the cervical canal, a fluid/catheter wire access port, and a handle member which is rotatably and axially movable on the shaft of the cannula but which can be locked at a desired position on the shaft of the cannula. A notch on a wing of the handle member engages with forceps to hold the cannula in liquid tight contact with the cervical canal. Extending beyond the end of the acorn is a curved tip, through whose open end the catheter wire is extended.
