Abstract
According to one aspect of the disclosure, a method of advancing a delivery catheter to a heart of a patient includes advancing a guidewire through the vasculature of the patient until the guidewire reaches a target treatment site in or adjacent to the heart. A dilator may be positioned within the delivery catheter so that a distal tip of the dilator extends beyond a distal end of the delivery catheter. The dilator may be advanced through the vasculature of the patient directly over the guidewire while simultaneously advancing the delivery catheter through the vasculature until the distal tip of the dilator reaches the target treatment site. While maintaining the distal tip of the dilator substantially stationary relative to the target treatment site, the delivery catheter may be advanced over the dilator until the distal end of the delivery catheter is positioned at the target treatment site.
