Abstract

Devices and methods for performing a transseptal puncture procedure using a device which includes either an untapered or tapered blunt end cannula disposed in an introducer carrying a sharp guidewire disposed longitudinally through the lumen of the blunt cannula, and a blunt end dilator wherein the guidewire is flexible and has an atraumatic shape at its tip. The cannula gives the more flexible introducer a defined shape and steerabilty allowing an ordinarily skilled physician to easily access a selected location on the septal wall of the heart for transseptal puncture and introducer placement thereacross without employing an exposed sharp end needle during the procedure.
