Abstract
A surgical seal assembly for use with a surgical access device includes a seal housing defining a central longitudinal axis and having a longitudinal passage dimensioned to permit passage of a surgical instrument through the seal housing, a gimbal mount disposed within the seal housing and having a gimbal seal member defining an aperture for substantial sealed reception of the surgical instrument, and an interface seal disposed within the seal housing. The gimbal mount is adapted for angular movement relative to the central longitudinal axis upon angulation of the surgical instrument whereby the gimbal seal member substantially maintains the sealed reception of the surgical instrument. The interface seal includes an interface seal member extending at least along the longitudinal axis and being in substantial contacting sealing relation with the gimbal mount. The interface seal member is adapted to maintain the sealing relation with the gimbal mount upon angular movement thereof.
