A retrieval device, comprising:
- a sheath including a lumen extending longitudinally through the sheath;
- an elongate member slidably disposed within the lumen;
- and
- a basket at a distal end of the elongate member, the basket including a plurality of legs formed integrally with the elongate member, wherein the elongate member and the basket are formed of a single wire, and the legs are made by splitting a length of the single wire.
