Original Abstract Submitted
Anatomical wall crossing systems, devices and related methods are disclosed in this patent document. A transseptal system, for example, can include a guidewire, a dilator, and a deflectable sheath configured to safely deliver a puncture needle through a septal wall associated with the fossa ovalis and into a central region of the left atrium of a heart. The dilator can include a dilator nose having a first outer diameter and a dilator beveled segment, extending proximal of the dilator nose, tapering from a second, greater outer diameter to the first outer diameter. The length and interplay of the puncture needle and the dilator nose can be configured such that the puncture needle is inhibited from bending and impinging upon the left side of the atrial septum of the heart during use. A body of the guidewire can include at least one loop segment to provide stable support in the left atrium for delivery of a diagnostic or therapeutic device along its more proximal portions. The deflectable sheath can position and align the dilator nose relative to the fossa ovalis.
