Abstract

An endoscopic stone extraction device (10) includes a handle (12) that supports a sheath (18), and a filment (22) such as a wire slidably disposed in the sheath (18). One end of the wire (22) is mounted to the handle (12) for rotation with respect to the handle (12) and the other end of the handle (12) supports a stone extraction basket (28). A manipulator (60) is provided on the wire (22) to allow a user to rotate the filament (22) and therefore the basket (28) with respect to the handle (12). The basket (28) can have a side-facing opening (100) or a rear-facing opening (100'). In either case, a stone retention region (102) is provided with relatively small openings (110) sized to retain stones smaller than two millimeters in diameter.
