Apparatuses, systems and methods for perforating and aspirating inner ear

An apparatus for penetrating an anatomic membrane, comprising:

• a tubular member including a proximal portion, a distal portion, and inner and outer surfaces defining a circumference around the tubular member,
• a plurality of apices extending from a distal end of said tubular member and arranged around the circumference,
• a plurality of valleys arranged around the circumference, wherein each valley adjoins neighboring apices, wherein the plurality of apices and the plurality of valleys define a plurality of serrated blades around the circumference and the plurality of apices and valleys define a circumferential crown shape,
• wherein each of the valleys are configured to include an inside bevel disposed on the inner surface of said tubular member in which the face of the inside bevel is directed toward a central axis of the tubular member, and
• the tubular member being configured to:
• translate between a first position and a different second position upon entering a membrane, and
• extract a portion of the membrane by engaging at least one apex of the plurality of apices with the membrane.
