Abstract

A surgical portal apparatus includes a housing and a cannula member. The housing includes a seal mount and a flexible housing wall. The cannula member is connected to the housing and defines a longitudinal axis and passageway. The seal mount has an internal seal. The flexible housing wall is dimensioned to permit both axial and radial movement of the seal mount with respect to the longitudinal axis between a first position of the seal mount and a plurality of second positions of the seal mount. The seal mount may be biased by a biasing member toward the first position. In an embodiment, the biasing member is a spring that is engageable with the cannula member and the seal mount.
