Abstract: A native leaflet treatment system and method for treating native heart valve leaflets before heart valve repair or replacement procedure. The treatment system includes a delivery apparatus configured to enter the heart, and a native leaflet treatment device stored in the delivery apparatus in a compressed state. The treatment device includes a clamping structure, which is configured to retain at least a portion of the native leaflets in the deployed state. The treatment device is delivered into the heart using the delivery apparatus, and released near the native heart valve, where the treatment device expands and the clamping structure captures and holds the native leaflet, such that the native leaflets will no longer block blood flow. This improves the dynamics of the blood flow which facilitates subsequent surgical procedures (minimally-invasive surgery or open surgery) for heart valve repair or replacement.
