Problems solved by technology

[0003] Due to the different parts of the vascular lesions in patients, especially the size, length, curvature and diameter of the lesions, it is impossible to use imported and domestically-made stents with uniform standards and models, thus losing the opportunity to implant stents. treat

Embodiment Construction

[0029] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0030] 1. Embodiment

[0031] Patient: ×××; Gender: Male, Age: 67 years old;

[0032] Clinical symptoms: retrosternal or precordial pain, palpitations, shortness of breath, sometimes dyspnea.

[0033] MRI (MR1) examination conclusion: single right coronary artery malformation, stenosis at the malformation, 3 / 5 atherosclerosis, thrombosis.

[0034] Treatment method: Inner stents are placed in the deformed and stenotic lesion to support the stenotic and occluded blood vessels, reduce the elastic retraction and reshaping of the blood vessels, and achieve the purpose of maintaining smooth blood flow in the official cavity.

[0035] Due to the deformity of the lesion segment, the patient could not use a commonly used stent, and the clinician suggested customizing a specific stent. According to the imaging data of the patient's nuclear magnetic resonance (MR1), a specific stent (length 15mm...

Abstract

The invention discloses a special-shaped bracket with holes implanted in the heart, brain and peripheral blood vessels and a manufacturing method thereof, and relates to medical devices implanted in the human body. The shape of the stent is a network structure with the same shape as the patient's blood vessels. The manufacturing method of the bracket mainly includes: designing the geometric figure of the bracket according to the data; designing and processing the special mold for the bracket; and making the special-shaped bracket with holes according to the special mold for the bracket. The stent has a simple structure, is convenient to manufacture, is safe and reliable, can ensure a stable geometric shape, has good physical and mechanical properties, and has good biocompatibility; the implantation completes the treatment at one time, shortens the operation time, relieves the pain of the patient and restores physical fitness as soon as possible. Reduce medical expenses; overcome the problem of patients needing two or more surgeries; applicable to various special-shaped heart, brain, arteries, veins, peripheral arteries, and veins.

Description

technical field [0001] The invention relates to a medical device implanted in a human body, in particular to a special-shaped stent with holes implanted in the heart, brain and peripheral blood vessels and a manufacturing method thereof. Background technique [0002] With the process of industrialization and population aging in our country, the incidence of vascular diseases is getting higher and higher. Stenotic and thrombotic lesions such as heart, brain and peripheral blood vessels seriously threaten human life and health. In order to prevent and treat vascular diseases, since the 1980s, It has been working tirelessly for generations. In 1983, my country achieved the first successful endovascular treatment—the patient with inferior vena cava septum was cured. Since the early 1990s, Chinese R&D personnel have conducted a series of research on vascular stents and vascular stent grafts. In 1992, the first case of using a domestic bare stent was successfully implanted in the...
