Claim 0:
1. A transseptal puncture system for use in a heart having a septum, the transseptal puncture system comprising:
a needle member that includes a distal end and a proximal end, wherein the needle member defines a first lumen therethrough and defines a needle axis, wherein the needle member includes a cylindrical needle wall that includes inner and outer surfaces and a distal end, wherein the first lumen is defined by the inner surface of the needle wall, wherein the distal end of the needle wall includes an inner edge surface, an outer edge surface and a circular shaped transverse leading edge surface, wherein the inner edge surface is non-parallel with the outer edge surface, wherein the inner edge surface is curved and extends between the circular shaped transverse leading edge surface and the inner surface, wherein the outer edge surface is curved and extends between the circular shaped transverse leading edge surface and the outer surface, wherein a leading edge plane is defined by the circular shaped transverse leading edge surface, and wherein the leading edge plane extends perpendicular to the needle axis,
a dilator that includes a distal end and a proximal end, wherein the dilator defines a second lumen therethrough, wherein the needle member is movable within the second lumen, and wherein the distal end of the needle member is configured to puncture the septum,
a sheath that includes a distal end and a proximal end, wherein the sheath defines a third lumen therethrough, wherein the dilator is movable within the third lumen,
a needle control device that is configured to move the needle member a predetermined distance from a stowed position to a deployed position, and
a guidewire that includes a distal end and a proximal end and is movable within the first lumen.
