4. The biopsy device of claim 1 , wherein at least one movable blade of the plurality of movable blades is initiated to pivot by a pushing action from the manipulation end.

5. The biopsy device of claim 1 , wherein the set depth or the depth selected is effected by a deployment of depth stops from the flexible sheath adjacent to the distal chamber initiated from the manipulation end.

6. The biopsy device of claim 1 , wherein the manipulation end includes a proximal chamber in fluid communication with the distal chamber, the proximal chamber configured to receive the plurality of specimens in an order and an orientation acquired upon exposure of a suction conveyed through the flexible sheath.

7. The biopsy device of claim 1 , wherein the plurality of specimens are removed from the distal chamber by a flushing fluid conveyed from the manipulation end with preservation of specimen order and orientation.

8. A biopsy system operable through an endoscope by a user comprising:

a flexible sheath having a terminus with a distal chamber configured with a forward facing cutting edge comprising a plurality of movable blades, the plurality of movable blades including two counter rotating blades positioned perpendicular or beveled relative to a long axis of the distal chamber, each counter rotating blade of the two counter rotating blades configured to pivot from a separate corresponding axis;

a manipulation end controllable by the user to plunge the forward facing cutting edge at a set depth or a depth selected by the user and to engage a cutting action by the plurality of movable blades at the set depth or the depth selected to acquire a plurality of specimens storable in the distal chamber; and

a proximal chamber in fluid communication with the distal chamber, the proximal chamber configured to receive the plurality of specimens in an order and an orientation acquired upon exposure of a suction conveyed through the flexible sheath.

9. The biopsy system of claim 8 , wherein the forward facing cutting edge includes a wire spanning across middle of the forward facing cutting edge and a plate beneath the wire, wherein the plurality of specimens are cut along the long axis to form a plurality of specimen half pairs, the specimen half pair kept separated by the plate.

11. The biopsy system of claim 8 , wherein at least one movable blade of the plurality of movable blades is initiated to pivot by a pushing action from the manipulation end.

12. The biopsy system of claim 8 , wherein the set depth or the depth selected is effected by a deployment of depth stops from the flexible sheath adjacent to the distal chamber initiated from the manipulation end.

13. The biopsy system of claim 8 , wherein the plurality of specimens are removed from the distal chamber by a flushing fluid conveyed from the manipulation end with preservation of specimen order and orientation.

14. A biopsy device operable through an endoscope by a user comprising:

a flexible sheath having a terminus with a distal chamber configured with a forward facing cutting edge comprising a plurality of movable blades, the plurality of movable blades including two counter rotating blades positioned beveled relative to a long axis of the distal chamber, each counter rotating blade of the two counter rotating blades configured to pivot from a separate corresponding axis; and

a manipulation end controllable by the user to plunge the forward facing cutting edge at a set depth or a depth selected by the user and to engage a cutting action by the plurality of movable blades at the set depth or the depth selected to acquire a plurality of specimens storable in the distal chamber.

15. The biopsy device of claim 14 , wherein the forward facing cutting edge includes a wire spanning across middle of the forward facing cutting edge and a plate beneath the wire, wherein the plurality of specimens are cut along the long axis to form a plurality of specimen half pairs, the specimen half pair kept separated by the plate.

16. The biopsy device of claim 14 , wherein at least one movable blade of the plurality of movable blades is initiated to pivot by a pulling action from the manipulation end.

17. The biopsy device of claim 14 , wherein at least one movable blade of the plurality of movable blades is initiated to pivot by a pushing action from the manipulation end.
