A device comprises an outer tube defining a longitudinal axis and comprising an aperture near a distal end thereof； a cutting element disposed within the outer tube and configured for rotation and movement across the aperture along the longitudinal axis, the cutting element comprising an engagement feature at a distal end thereof； and a distal tip comprising a tapered distal end and a proximal end that comprises a mating feature. The cutting element may be configured to rotate and cut tissue as it moves along the longitudinal axis across the aperture until the engagement feature at least partially engages the mating feature of the proximal end of the distal tip and entrains the distal tip in oscillation along the longitudinal axis and/or rotation.
