摘要：
A bodily duct obstruction retrieval device that includes a self-expandable member that is capable of transitioning between unexpanded and expanded states. According to some implementations the inner wall surface of the self-expandable member has one or more features protruding therefrom that are adapted to engage the obstruction as the self-expandable member transition from the expanded state toward the unexpanded state. According to other implementations the outer wall surface of the self-expandable member also has one or more features protruding therefrom that are adapted to engage the obstruction as the self-expandable member transition from the unexpanded state toward the expanded state.
