Abstract
A tapered cannula is provided for maintaining gas pressure within a body cavity during an intracavity procedure. The cannula is long enough to penetrate into the body cavity and has an exterior diameter tapering downward from the proximal end to the distal end. In use the cannula is inserted sufficiently far that the cannula creates a leakproof seal with incision. Another device is provided that serves a similar purpose, except that it does not extend into the body cavity. This device has the added feature of providing a platform that is anchorable to surrounding skin.
