Abstract
A seal assembly for use with an access apparatus includes an integral filter and evacuation port for filtering of fluids, e.g., smoke, from an operating site and removing contaminants and/or odor from the fluids for release of the filtered fluids into the ambient atmosphere. The seal assembly may be a separate subassembly or component which is releasably couplable to the access apparatus or may be integral with the access apparatus. The seal assembly defines its own flow path independent of the insufflation mechanism of the cannula assembly, and is capable of filtering fluids even in the presence of a surgical object positioned within the cannula assembly.
