| Abstract: |
A disposable uterine evacuation assembly for applying aspiration curettage to the uterine cavity wall. A hollow transparent plastic cannula is connected by a flexible plastic tube to a receptacle which is in turn connected to a vacuum source for applying vacuum pressure to an inlet slot in the tip portion of the cannula. The receptacle consists of a pair of nested transparent plastic bags, the inner bag being perforated to trap solids therein while permitting liquids to flow into the outer bag. The cannula has a rigid handle section and a flexible intermediate section which permits bending to conform to the curves of the cervical canal, and the slot in the cannula tip is arranged parallel to the longitudinal axis of the cannula and has flattened edges to provide flush engagement against the uterine cavity wall.

What is claimed is:
1. For use in a uterine evacuation assembly for applying aspiration curettage to the wall of a uterine cavity from a vacuum source, a hollow cannula comprising a distal tip section, an intermediate flexible section and a rigid handle section joined together to form an integral unit, said handle section having means for attachment to said vacuum source, said tip section having a tubular body wall of circular cross section, a portion of said wall at the distal end thereof being cut away to form flat edges defining therebetween an elongated slot extending parallel to the longitudinal axis of said tip section for engagement with said uterine cavity wall and the application of suction thereto when vacuum is applied to the interior of said cannula, said distal tip section having a curved wall overlying said slot and extending across the distal end of said tip section, said curved wall having a thickness sufficiently small to enable said wall to flex and flatten out upon engagement with the wall of said uterine cavity.
