Abstract
A trocar having a cannula and a valve housing with a polygonal configuration, provides for a floating septum where the float is encouraged in a first direction and restricted in a second direction. The septum includes multiple septum valves which may function with a comnron zero-closure valve, or individually in a valve assembly with an associated zero-closure valve. Various seals can be configured to prevent blow-back. Cup valves, check valves, and reciprocating valves are contemplated, along with various skirt configurations for maintaining pressurized air within the trocar.
