longitudinally movable within the sheath 22 and the suitable operating mechanism or means will control movement of the control wire 24 therethrough the device further includes a pair of biopsy jaws 26 connected to a housing 28 which is fixedly attached to the second end of the sheath 22 the biopsy jaws 26 are operatively connected to the control wire 24 by an actuator 30 which will be more fully described herein at least one of the jaws 26 is moveable between open and closed positions with respect to the other of the jaws 26 however in the embodiment shown both jaws 26 are moveable between open and closed positions although many other configurations are envisioned in an exemplary embodiment the sheath 22 would be formed from two welded sections of coil 32 34 the distal portion of the sheath 22 is preferably more flexible than the proximal portion the added flexibility may be created by tapering the coil 34 by grinding in another embodiment shown in fig1 the sheath is formed of three sections which are laser welded together although other sizes may be used the present embodiment uses three sections which are preferably formed of coils which are 0 4 0 5 and 0 6 mm.
