Abstract
An energy assisted tissue piercing device that enables a tissue piercing wire to puncture heart tissue percutaneouly. The energy assisted tissue piercing device includes an outer delivery catheter, an inner tissue piercing wire, and an energy source. The inner tissue piercing wire is disposed longitudinally through the lumen of the outer delivery catheter during delivery. The inner needle has a flexible portion that allows the wire to bend when it is free from the constraint of the outer delivery catheter. The inner tissue piercing wire is conductive and connected to an energy source and the piercing of the heart tissue is done with the aid of the energy from the energy source.
