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.

Abstract: A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.
