Vascular stent system and application method thereof

Abstract

The invention provides a vascular stent system and an application method thereof. The vascular stent system comprises a radial expansion balloon, a balloon expansion dilating catheter and a radial expansion stent; the position between the radial expansion balloon and the radial expansion stent is enclosed with a guide wire reserved channel, a guide wire reserved channel protection tube and a protection tube filler are arranged in the guide wire reserved channel, the inner wall of the guide wire reserved channel is attached to the guide wire reserved channel protection tube, and the guide wire reserved channel protection tube is filled with the protection tube filler. The application method of the vascular stent system includes: taking out the protection tube filler from the guide wire reserved channel protection tube; piercing additional guide wires out of the guide wire reserved channel protection tube and a center wire out of the balloon expansion dilating catheter; taking out the guide wire reserved channel protection tube; moving the radial expansion balloon and the radial expansion stent to corresponding vascular disease sites along the center guide wire and the additional guide wires for treatment of vascular diseases. The vascular stent system and the application method thereof have the advantages of high long service life and high security and can be applied to narrow blood vessels and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a vascular stent system and a method for using it. Background technique [0002] At present, cardiovascular disease has become one of the major diseases that threaten human health and life, and vascular stents have been widely used as an important treatment for cardiovascular diseases. During the treatment process, vascular stents are implanted into the blood vessels of the human body to achieve the purpose of treating and preventing vascular diseases such as vascular stenosis, blockage, aneurysm and dissection. [0003] Existing vascular stent systems usually include a radially stretchable balloon, a balloon expansion catheter pierced through the center of the balloon, and a radially stretchable stent wrapped on the outer surface of the radially stretchable balloon. During the treatment of vascular lesions, the central guide wire passes through the balloon expansion catheter, and...
