Beschreibung
Zusammenfassung:	A surgical portal and introducer assembly includes an introducer defining a longitudinal axis and having a longitudinal passageway and a portal member positionable within the longitudinal passageway of the introducer. The portal member is adapted for positioning within a tissue tract and has at least one longitudinal port for passage of a surgical object. The portal member comprises a compressible material and is adapted to transition between a first expanded condition to facilitate securing of the portal member within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract and a second compressed condition to facilitate at least partial insertion of the portal member within the tissue tract. The assembly may include an expandable restraining member at least partially disposed within the longitudinal passageway of introducer. The restraining member is adapted to expand and compress the portal member to cause the portal member to assume the compressed condition thereof, to thereby facilitate passage of the portal member through the longitudinal passageway of the introducer and into the tissue tract.
