Patent abstract
Methods of providing suction may include providing suction patterns having varying intensity levels, such as a “crescendo suction” pattern. Cycles of crescendo suction patterns may comprise variable intensities of negative suction in a crescendo pattern (such as a small intensity negative suction pressure, a medium intensity negative suction pressure, and a large intensity negative suction pressure). The suction patterns may include pauses or temporary stops to the negative suction pressure.
