Embodiment Construction
[0052] The following description is only used to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments in the following description are only examples, and those skilled in the art can think of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the present invention.
[0053] The invention provides an embolization coil, specifically an embolization coil for embolizing blood vessels and hemangioma, and is a medical device for minimally invasive treatment. The embolic coil includes a single or multiple first wires 10, or the embolic coil includes at least one first wire 10 and one second wire 10A.
[0054] The surface of the first wire 10 first needs to be polished or sandblasted to reduce the surface finish of the f...

The invention provides an embolic spring ring and a manufacturing method thereof, wherein the embolic spring ring is manufactured by twisting a single or a plurality of first wires into a spiral shapeand forming a plurality of spiral grooves and a plurality of spiral bulges and then coiling the spiral grooves and the spiral bulges into a spring shape, or is manufactured by twisting and winding atleast one first wire into the spiral shape in the same direction by taking another straight second wire as a center, forming a plurality of spiral grooves and a plurality of spiral bulges, and coiling the spiral grooves and the spiral bulges into the spring shape. The first wire is firstly ground or sandblasted, and a cross section of the first wire is modified into a plurality of unconventionalcircular shapes such as flat shapes, ellipses, rectangles, polygons or special shapes in a rolling or cold drawing mode, so that a plurality of bulges or grooves are formed on the surface of the firstwire, and a friction force between the embolic spring ring and an aneurysm or a blood vessel is increased, thereby effectively preventing moving and running phenomenon of the embolic spring ring andreducing a specific gravity and the cost of the wire of the embolic spring ring.
Description
Technical field [0001] The present invention relates to an embolization coil and a manufacturing method thereof, in particular to an embolization coil that can prevent displacement in hemangioma or blood vessels. The embolization coil can be effectively used for minimally invasive treatment of hemangioma and other vascular diseases treatment. Background technique [0002] Hemangioma refers to a kind of tumor-like protrusion and arteriovenous malformation of the arteriovenous wall caused by the abnormal expansion of the arteriovenous lumen. The more common intracranial aneurysm. With the rapid development of embolization coil products, embolization of aneurysms is now a popular treatment method. The principle is to use embolization coils at the front or back of the arteriovenous vessels that have problems to block the blood vessels and block the blood. Flow in the blood vessels. The conventional process of embolizing aneurysms is to puncture the femoral artery, insert the guidin...
