A biopsy device comprises a coring and transport assembly and a distal beak assembly. The distal beak assembly may be coupled to or near a distal end of the coring and transport assembly and may comprise at least one movable cutting element. The distal beak assembly may be configured to rotate about an axis, and assume at least a first open configuration operative to enable the at least one cutting element to core through tissue and a second closed configuration operative to enable the at least one cutting element to move through the tissue and to sever a cored specimen from the tissue. |
