Abstract
A surgical portal apparatus includes a portal housing, an elongated portal member connected to the portal housing and an armature assembly. The portal housing and the portal member have an axial bore for reception and passage of a surgical object. The armature assembly includes at least two arms disposed within the portal housing and an outer mount. The at least two arms extend at least radially inwardly and are adapted to move relative to the longitudinal axis from a rest position to an activated position during passage of the surgical object. The at least two arms are operatively connected whereby movement of a first arm causes corresponding movement of a second arm. The outer mount comprises a resilient material and is mounted to the at least two arms, and imparts a biasing force thereto toward the rest position.
