In embodiments of an obstruction removal device, system, and/or method, an expandable member is configured to be slidably coupled to a guide wire. The expandable member is configured to surround at least a portion of an obstruction captured by a stentriever as the expandable member transitions from the expanded state to the contracted state, i.e., when the guide wire is removed from a vasculature to remove the stentriever and the obstruction from the vasculature. A first locking member is located at a base of the expandable member. The first locking member is configured to engage a second locking member that is located on the guide wire, the stentriever, or an inner surface of a guide catheter, thereby coupling the expandable member to the guide wire, the stentriever, or the inner surface of the guide catheter when the expandable member is deployed within the vasculature.
