Claim 15:
16. A medical device assembly comprising:
a sheath, the sheath comprising:
an elongated sheath shaft, the sheath shaft having a first bend region, a central lumen and a distal end,
a first steering wire, the steering wire having a first position and a second position, wherein at the first position the first bend region is substantially linear, and wherein at the second position the distal end of the sheath is substantially perpendicular to a longitudinal axis of the sheath,

a catheter inside the sheath, the catheter comprising:
a catheter shaft,

a shaped blade, the shaped blade comprising:
a blade cutting edge that is oriented at a substantially right angle to the longitudinal axis of the sheath when the sheath is oriented substantially perpendicular to the inter atrial septum, and is adapted to cut a 3 mm or larger durable aperture in the interatrial septum,

a tissue articulator, the tissue articulator having a first setting and a second setting, the tissue articulator being adapted to hold the interatrial septum against the shaped blade for cutting while in the second setting,
an actuator connected to the tissue articulator, the actuator having a first position and a second position, wherein when the actuator is in the second position the tissue articulator holds the interatrial septum against the shaped blade.
