A seal anchor member has opposing ends that define a longitudinal axis. The seal anchor member is adapted to transition between an expanded condition and a compressed condition to facilitate securing of the seal anchor member within a tissue tract in a substantially sealed relationship. The seal anchor member includes a biasing member positioned along the longitudinal axis. The biasing member is configured and adapted to facilitate the transition between the expanded and compressed conditions. The seal anchor member further includes at least one lumen extending through the seal anchor member for slidably receiving a surgical instrument. |
