Abstract
A medical retrieval device has a multi-prong retrieval assembly. The multi-prong retrieval assembly has a first position, in which the retrieval assembly extends from the distal end of the sheath to form an open ended grasping device, and a second position, in which the retrieval assembly extends from the distal end of the sheath to form a substantially close ended basket-type retrieval device. When the retrieval assembly is used as a basket-type retrieval device, the distal ends of the prongs of the retrieval assembly that form the basket are not connected to each other. Thus, captured objects may be released by the operator, or by applying sufficient force to separate one or more of the prongs.
