Apparatus and Methods for Removing an Obstruction from a Bodily Duct of a Patient
First Claim
1. A bodily duct obstruction retrieval device comprising:
- a self-expandable member that is capable of transitioning between unexpanded and expanded states, the self-expandable member comprising a wall formed by a plurality of interconnected struts, the interconnected struts forming a plurality of cell structures in the wall, the interconnected struts forming the wall having an inner surface and an outer surface, at least some of the interconnected struts having multiple gaps formed in the inner surface, the gaps being separated by protruding elements that are configured to engage the obstruction as the self-expandable member transition from the expanded state toward the unexpanded state, the self-expandable member having a proximal end and a distal end.

Abstract
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.
