Patent ID: 7963928

Claim:
A multiple stage core biopsy assembly to automatically obtain a tissue specimen during a first stage and deliver a material in the biopsy track during a second stage, said assembly comprising: a. an outer casing, said outer casing having a hollow body, and a handle, b. a power supply, said power supply being connected to a circuit board, c. circuit board, said circuit board supporting electronic circuits, electrical components, and a microchip having a program, said circuit board being powered by said power supply, d. a single trigger mechanism, said single trigger mechanism initiating said program, e. a multiple stage delivery mechanism, said multiple stage delivery mechanism having motors activating and controlling movable mechanical components, said motors being activated by said program, and being supported within said body of said outer casing, f. a removable core biopsy unit to cut and retain tissue in said first stage, said core biopsy unit, being dimensioned to be retained and movable with said multiple stage delivery mechanism, g. a removable material delivery unit, adjacent to and actuating independent of said core biopsy unit, to deliver said material into said biopsy track in said second stage, said removable material delivery unit being dimensioned to be retained within and positioned to be moved by said multiple stage delivery mechanism, wherein said mechanical components within said multiple stage delivery mechanism move said core biopsy unit during said first stage to take said biopsy and said material delivery unit to deliver said material to said biopsy track during said second stage, said core biopsy unit and said material delivery unit forming a biopsy/delivery sub-assembly.
