         25 . The device according to  claim 24  wherein the tool is a basket, a grasping device, or a sampling device. 
     
     
         26 . The device according to  claim 24  wherein the articulator further comprises two finger grooves or two finger-holes. 
     
     
         27 . The device according to  claim 24  wherein the articulator is movably connected to the body via a pivot pin. 
     
     
         28 . The device according to  claim 24  wherein the articulator further comprises at least a first and a second pivot pin, wherein at least one wire is in communication with the first pivot pin or the second pivot pin. 
     
     
         29 . The device according to  claim 24  wherein the articulator further comprises at least a first and a second pivot pin, wherein the first wire and the second wire are in communication with the first pivot pin and the second pivot pin. 
     
     
         30 . The device according to  claim 24  wherein the articulator further comprises a first pivot pin, a second pivot pint, and a third pivot pin; wherein the first wire is connected to the first pivot pin and the second pivot pin, and the second wire is connected to the third pivot pin. 
     
     
         31 . The device according to  claim 24  further comprising a wire connection point; wherein the distal ends of the first wire and the second wire are connected via a soldered point, a loop, or a connection disk. 
     
     
         32 . The device according to  claim 24  wherein the body further comprises an axis where along the articulator can move in a proximal and a distal direction. 
     
     
         33 . The device according to  claim 24  wherein the first and second wires further comprise wire fibers and the wire fibers are in a net-configuration. 
     
     
         34 . A method for retrieving an object, the method comprising:
 inserting a device for removing an object into a patient;   extending a tool of the device out to the object;   articulating the tool to encapsulate the object; and   retracting the tool to retrieve the object, wherein the extending and the articulating are capable of being performed simultaneously or the articulating and the retracting are capable of being performed simultaneously.   
     
     
         35 . The method according to  claim 34 , wherein the tool is a basket, a grasping device, or a sampling device. 
     
     
         36 . The method according to  claim 34 , wherein the tool is articulated by an articulator moveably connected to the device. 
     
     
         37 . The method according to  claim 36 , wherein the articulator further comprises two finger grooves or two finger-holes. 
     
     
         38 . The method according to  claim 36  wherein the articulator is movably connected to the body via a pivot pin. 
     
     
         39 . The method according to  claim 36  wherein the articulator further comprises at least a first and a second pivot pin, wherein at least one wire is in communication with the first pivot pin or the second pivot pin. 
     
     
         40 . The method according to  claim 36  wherein the articulator further comprises at least a first and a second pivot pin, wherein the first wire and the second wire are in communication with the first pivot pin and the second pivot pin. 
     
     
         41 . The method according to  claim 36  wherein the articulator further comprises a first pivot pin, a second pivot pint, and a third pivot pin; wherein the first wire is connected to the first pivot pin and the second pivot pin, and the second wire is connected to the third pivot pin. 
     
     
         42 . A medical device, the device comprising:
 a body;   an articulator movably connected to the body, the articulator comprising at least a first and a second pivot pin, wherein the first wire and the second wire are in communication with the first pivot pin and the second pivot pin;   at least a first and a second wire having distal ends;   the first and second wire in communication with the articulator;   a sheath at least partially disposed about the first and second wire;   a tool disposed at the distal end of the first and second wire, wherein the articulator is capable of moving the tool outside the longitudinal plane; and   wherein the tool is capable of being extended and retracted in a longitudinal plane simultaneously with movement outside the longitudinal plane.   
     
     
         43 . The device according to  claim 42  further comprising a wire connection point; wherein the distal ends of the first wire and the second wire are connected via a soldered point, a loop, or a connection disk.
