Abstract
A surgical portal and introducer assembly includes an introducer and a portal member positionable within a 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 and a second compressed condition. The assembly may include an expandable restraining member that may be disposed within the longitudinal passageway. The restraining member is adapted to expand and compress the portal member to cause the portal member to transition to the compressed condition.
