1. An apparatus for filling a fallopian tube and sealing the opening to the fallopian tube to be examined with a desirable saline solution for ultrasonic examination, and for simultaneously filling the uterus with a saline solution and sealing the cervix for ultrasonic examination, comprising:

  • a first conduit having a proximal end and a distal end and a first liquid orifice at said distal end, and having a first lumen and a second lumen;

    a first inflatable elastic member sized in diameter to seal a cervical opening when inflated disposed at the distal end of said first conduit and in fluid communication with said first lumen and sealed to said first conduit so that liquid under pressure injected into said first lumen would cause said elastic member to inflate radially, said elastic member disposed adjacent the distal end of said first lumen;

    a third lumen having a proximal end and a distal end and in fluid communication with a first liquid orifice in the distal end of said first conduit;

    a second conduit having a proximal end and a distal end and a liquid orifice at its distal end, and having a fourth lumen and a fifth lumen, each having proximal and distal ends, said second conduit disposed within said second lumen;

    a second elastic member sized to seal a fallopian tube opening when inflated disposed at the distal end of said second conduit and in fluid communication with said fourth lumen and sealed to said second conduit so that liquid under pressure injected into said fourth lumen would cause said second elastic member to inflate radially, said second elastic member disposed adjacent the distal end of said fourth lumen;

    said fifth lumen in fluid communication with a liquid orifice in the distal end of said second conduit;

    first dispensing means connected to the proximal ends of said first lumen and said third lumen for selectively dispensing a fluid within said first lumen and said third lumen; and

    second dispensing means connected to the proximal ends of said fourth lumen and said fifth lumen for selectively dispensing liquid within said fourth and said fifth lumens;

    wherein said first dispensing means can dispense a saline solution for inflation of said first elastic member for sealing the cervical opening and for delivery to the uterine cavity through said first liquid orifice, and said second dispensing means can dispense a saline solution for inflation of said second elastic member and for delivery to the fallopian tube through said liquid orifice in said second conduit.
