Abstract: A surgical apparatus includes a housing member and an inner member. The housing member includes an expandable material that is adapted to transition between a compressed condition and an expanded condition. In the expanded condition, an outer surface of the housing member is adapted for a substantial sealing relationship with tissue upon insertion of the housing member within the tissue for accessing an underlying tissue site. The housing member has leading and trailing ends that define a longitudinal axis. The inner member is operably associated with the housing member and includes one or more longitudinal portals extending therethrough adapted for substantially sealed reception of a surgical object. The inner member may be less compliant than the housing member. The inner member may rotate about the longitudinal axis of the housing member.
