Embodiment Construction

[0032] The following description is provided to enable those skilled in the art to utilize the present invention and to suggest the best mode contemplated by the inventors to carry out the invention. However, since the general principles have been specifically defined in the present invention, and a negatively charged vascular stent and its manufacturing method are provided, various corresponding modifications remain obvious to those skilled in the art.

[0033] A central objective of the present invention is to reduce the risk of recurrent thrombosis. The vascular stent of the present invention is characterized by high biocompatibility, including hemocompatibility and temporally stable anticoagulant and anticoagulant properties, and can be implanted into coronary arteries or other arteries to restore their patency. The cylindrical small lattice frame formed by the blood vessel stent is composed of at least one wire-shaped component, which is coated with a coating having an el...

Abstract

An insertable into a human body article is coated with a coating of electret structure. The coating has an integral surface which blankets an entire surface of the article.

Description

technical field [0001] The present invention relates to a medical device for reducing the risk of thrombosis, and more particularly to a stent carrying a stable negative charge. Background technique [0002] A stent is an artificial "tube" that is inserted into a natural channel / duct in the body to prevent, or counteract, local flow constriction caused by disease. After balloon angioplasty, multiple stents are inserted into narrowed coronary arteries to help keep them open. Afterwards, the stent allows blood and oxygen to flow normally to the heart. Multiple stents placed in narrowed carotid arteries (multiple blood vessels in the front of the neck that supply blood to the brain) have been shown to be useful in treating patients at high risk of stroke. WO / 1996 / 041589 discloses a device for implantation in a blood vessel or hollow lumen in the human or animal body, such as a self-expanding stent, a venous filter, an embolization device or a support device, which It include...
