      SOLUTION: The device 10 retrieves the material from the body. The device 10 includes: a sheath 12 having a lumen extending therethrough and having a distal end; and a basket 16. The basket 16 is movable relative to the sheath 12 from a retracted position in which the basket 16 is withdrawn within the lumen of the sheath 12 to an expanded position in which the basket 16 is extended beyond the distal end of the sheath 12 and open. The basket 16 has a first portion and a second portion with two or more legs extending from the first portion to the second portion. The basket 16 further includes an intermediate portion between the first and second portions in which the legs are spirally arranged, substantially parallel, and non-intersecting. The intermediate portion of the basket 16 is displaced radially outward relative to the first and second portions when the basket 16 is in the expanded position.
