Abstract
A biopsy device suitable for collection of a tissue sample from a biopsy site in a body lumen is provided. The biopsy device comprises a combination of an introducer assembly, a cutter assembly, and an endoscope assembly that coact with one another. The introducer assembly includes a hollow sheath having a distal end portion defining an aperture suitable for receiving a tissue mass therein. The cutter assembly includes a cutter tube having a distal end portion with a cutting edge. The cutter tube is sized to fit axially within the introducer sheath. The endoscope assembly includes a bundle of optical fibers sized to fit axially within the cutter tube. In use, the fiber optic bundle of the endoscope is nested within the cutter tube, which in turn is nested within the introducer sheath to form a co-axial structure.
