Abstract

An endoscopic biopsy device having an outer sheath that is transparent, at least along a portion thereof, to allow visualization of at least a portion of the inside of the device. A distal portion of the outer sheath may be relatively more opaque or relatively less reflective to avoid glare that may otherwise result due to the sheath reflecting light from the endoscopic light source.
