Aortic septal fenestration device

Abstract

An aortic fenestration device having an outer sheath; a suction head being operably coupled to a distal end of the outer sheath and having a suction aperture; a fenestration element disposed within the outer sheath and extendable through the suction head to a position beyond the suction aperture to fenestrate tissue; a guidewire slidably disposed relative to the fenestration element and extendable to a position beyond the suction aperture and a distal end of the fenestration element; and a suction source operably coupled to the outer sheath and configured to exert suction pressure at the suction aperture of the suction head to selectively couple the suction head to the tissue via suction pressure as the tissue is fenestrated. The fenestration element can comprise a needle-wire and needle-wire catheter or a hollow needle.
