1. An Intravascular articulated and actuating retrieval apparatus comprising:
a) a mechanical user interface on an interface end;
b) an apparatus conduit coupled to the user interface, said apparatus conduit comprising:
i) a user end coupled to the user interface; and
ii) a distal end;
wherein said apparatus conduit extends from the user end to the distal end;
c) a first actuating portion coupled to the distal end of the apparatus conduit and comprising a first pivot,
d) a retrieval implement comprising a coil hook coupled to the first actuating portion and comprising a first retrieval implement portion:
said user interface comprising:
i) a first actuator configured to actuate the first actuating portion to rotate about said first pivot;
ii) a retrieval actuator configured to actuate said first retrieval implement portion from an open position to a closed position;
e) a first actuating portion first line extending from the first actuating portion to the first actuator and through the apparatus conduit;
f) a retrieval line extending from the retrieval implement to the retrieval actuator and through the apparatus conduit;
g) a first actuating portion second line extending from the first actuating portion to the first actuator and through the apparatus conduit;
wherein the first actuator comprises a first manipulator coupled to the first actuating portion first line and the first actuating portion second line, wherein rotation of the first manipulator in a first first-manipulator direction pulls the first actuating portion first line to rotate the first actuating portion about the first pivot a first rotational direction;
wherein rotation of the first manipulator in a second first-manipulator direction, opposite the first first-manipulator direction, pulls the first actuating portion second line to rotate the first actuating portion about the first pivot a second rotational direction, opposite the first rotational direction;
wherein the first manipulator is a first dial.
