A basket to grasp foreign matter for use with a basket forceps assembly comprising: a plurality of resilient wires being bundled together at each of their ends and being biased so as to define a basket to grasp foreign matter therein when said plurality of resilient wires is in an expanded position; said plurality of resilient wires capable of being passed through a flexible tube of a basket forceps assembly when said plurality of resilient wires is in an unexpanded position; and said resilient wires further characterized in that at least one of the resilient wires have tensile strengths which are lower than different, higher tensile strengths, associated with remaining ones of said plurality of resilient wires so that if any one of said at least one wires break all of said plurality of wires remain connected to said basket and are retrievable from the location of said foreign matter.
