Abstract
A guidewire that is specifically designed for performing an intracardiac transseptal puncture procedure is described. A piercing head for the guidewire has a conically-shaped section that tapers to a cutting section comprised of three tapered facets extending to a pointed tip. The three facets form three cutting edges that each provide for smooth cutting of body tissue, for example, cutting of the septum wall. The cut tissue does not tend to close or relax as readily as if the tissue had been punctured with a conically-shaped piercing tip, for example, one that has a structure similar to a pencil tip, This helps with subsequently moving a catheter and similar medical device through the pierced body tissue. Consequently, the faceted piercing head leaves an opening having a diameter that is substantially similar to the maximum outer diameter of piercing head.
