Abstract

The invention provides a recyclable heart stent. The recyclable heart stent comprises a transmission assembly, an elastic mesh bag and a heating device, the transmission assembly comprises a catheterand a gasbag, the gasbag is fixedly arranged at one end of the catheter, the gasbag is sleeved with the elastic mesh bag, and the elastic mesh bag is made of a plurality of elastic tubes connected toeach other; the elastic tubes are filled with liquid metals, the heating device is used to heat the liquid metals in the elastic tubes, and in the recyclable heart stent, the elastic mesh bag confinesthe liquid metal to form a stent body; at the time of implantation, the structure of the elastic mesh bag is changed by inflating the gasbag, and the liquid metals are solidified so that the stent body maintains a specific shape structure; and at the time of recycling, the liquid metals are melt, the structure of the stent body is reduced by the inflating and the deflating of the gasbag and the elasticity of the elastic mesh bag, and then the stent body is brought out of the human bodies through the catheter. In addition, the liquid metals have the advantages of good bio-compatibility, anti-thrombus and anti-corrosion, and the liquid metals have no damage to the blood vessel wall so that the stimulation of blood vessels to cause the inflammatory reaction is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a recoverable heart stent. Background technique [0002] Heart stent, also known as coronary artery stent, is a commonly used high-value consumable medical device that needs long-term intervention in the heart and has physiological and mechanical functions consistent with the beating heart. The role of heart surgery and future stabilization of the disease has a vital purpose. [0003] At present, cardiac stents have gone through the development process of metal stents, coated stents, and dissolvable stents. At present, the development of the third-generation stents is not yet mature, and the market is still dominated by the second-generation coated stents. The main materials are stainless steel, nickel-titanium alloy or cobalt-chromium alloy. [0004] For patients with myocardial infarction, stent implantation is an immediate treatment. However, the current heart stent...
