A contact activated incision device comprises a housing defining a cavity and a longitudinal axis extends between a proximal end and a distal end of the housing. A slider is slidable with respect to the housing along the longitudinal axis and at least partially positioned outside of the housing. A roller is mounted on the housing and rotatable about an axis perpendicular to the longitudinal axis. A blade assembly is mounted on the roller and has a blade wherein the blade is movable from a retracted position to an extended position and to a final position at the retracted position the blade is positioned in the cavity at the extended position the blade extends at least partially beyond the proximal end of the housing and at the final position the blade is positioned in the cavity.
