Transcatheter prosthetic heart valve delivery system with flush report

A system for performing a therapeutic procedure on a defective heart valve of a patient, the system comprising:

• a delivery system including:
• a shaft assembly including a distal portion, an intermediate portion, and an inner lumen extending through the shaft assembly;
• a sheath assembly defining an outer lumen sized to slidably receive the shaft assembly;
• and
• at least one flush port formed in the intermediate portion, the at least one flush port extending through multiple shafts and in fluid communication with the inner lumen and the outer lumen;
• a prosthetic heart valve having a stent frame and a valve structure attached to the stent frame and forming at least two valve leaflets, the prosthetic heart valve being self-expandable from a compressed arrangement to a natural arrangement;
• and
• wherein the delivery system is configured to slidably receive the prosthetic heart valve over the distal portion within the sheath assembly and is configured to be operable 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in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve to permit the prosthetic heart valve to self-expand to the natural arrangement and release from the delivery system.
