Beschreibung
Zusammenfassung:	An apparatus and method for capturing material within a body lumen are disclosed. The apparatus includes a core wire extending from a proximal end to a distal tip, an actuator member defining a lumen for receiving at least a portion of the core wire, and a distal basket having a distal enclosed end fixed relative to the core wire and one or more elements extending from a proximal open end to a collar slidable on the core wire. The collar is slidable on the core wire within an interior of the distal basket such that, when the collar contacts the actuator member, the collar applies an inward force to direct the proximal open end of the distal basket radially inwardly.
