ABSTRACT:
The present invention pertains to a device for deploying and retrieving a flexible tissue containment sac within a body cavity, through a minimal access incision. The device generally includes a tubular introducer having a flexible tissue containment sac disposable in a compressed configuration within the lumen of such tubular introducer. An elongate plunger shaft or pushing member is insertable or passable through at least a portion of the introducer lumen to push the containment sac out of the distal end of the lumen. Attached to the containment sac and extending through the lumen of the introducer is a tether. A portion of the tether may extend out of the proximal end of the introducer. The proximal end of the tether may be grasped and pulled in a proximal direction to pull the containment sac to a retrieved position on the end of an extractable shaft or, in embodiments absent such extractable shaft, to pull at least a portion of the containment sac into the introducer lumen.
