1. An endoluminal punch for punching a hole in the fossa ovalis, said punch comprising:
an outer tube characterized by a proximal end, a distal end, and a flexible region at the distal end, said flexible region characterized by a proximal end and a distal end; and
a cutting stylet slidably disposed within the outer tube said cutting stylet comprising a cutting stylet tube with a cutting stylet lumen communicating with a cutting stylet window on a side of the cutting stylet tube, proximate the distal end of the cutting stylet tube, said cutting stylet further comprising a cutting stylet wire comprising a proximal wire segment slidably disposed within the cutting stylet lumen, a cutting wire segment disposed on the distal end of the proximal wire segment, and a distal wire segment disposed on the distal end of the cutting wire segment, said distal wire segment longitudinally fixed to the cutting stylet tube, whereby distal translation of the proximal wire segment relative to the cutting stylet tube causes radially outward bending of the cutting wire segment through the window.
