ABSTRACT:
A surgical valve prevents loss of insufflation gas (or the like) when no instrument traverses the valve lumen. The valve is suitable for passing surgical implements distally, and for passing enlarged bodies (such as large morcels of severed tissue) proximally. A first set of valve segments angle together along a slit, similar to a duck-bill valve. A second set of valve segments angle outwardly distally, the second segments often having a passage so that distal pressure pushes the first segments together along the slit.
