The cylindrical sleeve is slidably movable relative to the tubular body causing the shield members to expand and deploy such that the shield members retain torn and fragmented soft tissue within an anatomical cavity. Means are provided on the tubular body to co-act with means on the cylindrical sleeve to lock the expanded and deployed shield members and secure the tubular body within an anatomical body.
