Abstract
A delivery system for use with a prosthetic heart valve having a stent frame to which a valve structure is attached includes a shaft assembly including a distal portion and an intermediate portion, and an inner lumen extending through the shaft assembly. The delivery system includes a sheath assembly defining an outer lumen sized to slidably receive the shaft assembly. At least one flush port is formed in the intermediate portion. The at least one flush port is in fluid communication with the inner lumen and the outer lumen. The delivery system is configured to transition from a loaded state in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve.
