Abstract

The embodiment of the invention discloses a delivery device, which comprises an outer delivery tube, a push rod, an inner tube, a functional handle and a plurality of connecting tubes, wherein one end of each connecting tube is connected with the push rod; the tube cavities of the connecting tubes are communicated with a metal wire passage in the push rod; the other ends of the connecting tubes are provided with connecting grooves; and the connecting grooves are communicated with the tube cavities of the connecting tubes. The connecting grooves are used for connecting the connecting port of a heart valve and the connecting tubes, and metal wires pass through the connecting port and are kept in the tube cavities of the connecting tubes, so that the metal wires are connected with the heart valve. The heart valve is fixed through the metal wires and the connecting grooves; when the heart valve is released, the metal wires must be extracted from the connecting grooves to finish release of the heart valve; therefore, before the heart valve is totally separated from the delivery device, the delivery device can be connected with the heart valve and can reclaim and reset the heart valve. The invention also discloses a heart valve delivery system.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a heart valve delivery system and a delivery device thereof. Background technique [0002] The valves of the heart are made of thin but extremely tough sheets of tissue that open and close as the heart contracts and relaxes. A normal human heart beats about 100,000 times a day, and its valves open and close about 100,000 times a day. Therefore, the valves of the heart must remain flexible and tense throughout a person's life, and can withstand the pressure of the heart chamber and the washing of blood for a long time. [0003] Valvular heart disease is one of the most common heart diseases in my country, mainly due to valvular damage caused by rheumatic fever; in recent years, with the development of aging population, valvular degeneration (including calcification and mucus degeneration, etc.) Damage is also increasing in our country; in addition, congenital val...
