Abstract
Embodiments hereof relate to centering devices for use with a valve delivery system and methods of delivering a valve prosthesis within a vasculature. A valve centering catheter is configured for use with a valve delivery system. The valve centering catheter includes a circumferential centering device at a distal portion thereof, and the circumferential centering device defines a central opening there-through when in an expanded configuration. The circumferential centering device is annular or has a C-shaped cross-section. The valve delivery system is tracked through the vasculature until the valve prosthesis is positioned through the central opening of the expanded circumferential centering device. The valve centering catheter may alternatively include a longitudinal centering device which acts as a marker for depth control during delivery of a valve delivery system, which may include an integral circumferential centering device.
