Abstract
A medical retrieval device includes a handle, two gear racks movably mounted to the handle for longitudinal movement, and a pinion rotatably mounted to the handle so as to engage the two gear racks. Rotation of the pinion moves the gear racks in opposite directions. A basket has at least three legs, an adjacent two of the legs being connected to one of the gear racks, and the remainder of the legs being connected to the other gear rack such that rotation of the pinion displaces the two legs in a first direction and displaces the remainder of the legs in a second direction. Thus rotation of the pinion articulates the basket.
