ABSTRACT:
A trocar includes a valve housing and cannula which define a working channel. A valve disposed in the valve housing along the working channel includes a gel material which defines a slit that functions as a zero seal in the absence of an instrument, and an instrument seal in the presence of an instrument. The slit is formed by mating gel components which are preferably separated during storage of the device. This separation can be facilitated by a pull strip which can be pre-lubricated and inserted into the slit for ultimate removal prior to activation of the trocar.
