Abstract
A system includes an access cannula, a deployment cannula having a plurality of engagement arms, and a containment bag. The deployment cannula is slidable within the access cannula between an initial condition, wherein the engagement arms are retained in a contracted configuration, and a deployed condition, wherein the engagement arms are disposed in an expanded configuration. The containment bag includes an open end portion configured to receive the first elongated tubular member and the second elongated tubular member. In the initial condition, a portion of the containment bag towards the open end portion is positioned adjacent at least one of the first elongated tubular member or the second elongated tubular member. In the deployed condition, the portion of the containment bag is expanded such that the portion of the containment bag is spaced-apart from the at least one of the first elongated tubular member or the second elongated tubular member.
