Background

As shown in fig. 1, most of the commonly used cardiovascular implants in the market are formed by laser cutting and then heat treatment molding using metal tubes, or formed by weaving and then heat treatment molding using metal wires as shown in fig. 2 to 4. However, many cardiovascular implants are connected with a delivery device through threads, so a threaded structure 1 'is usually additionally connected to the connecting end 21' for a tubular cardiovascular implant, and the thread-woven cardiovascular implant needs to be provided with the threaded structure 1 'at the connecting end 21' and also needs to close and close the woven threads into a closed-loop structure. The above structure has the following problems:

first, since the wire-braided cardiovascular implant 3 'and the tube-like cardiovascular implant 2' require the threaded structure 1 'to be connected at the connection end 21', the height of the convex portion is inevitably increased, thereby increasing the risk of micro-thrombosis.

Secondly, the braided wires of the wire-braided cardiovascular implant 3' are all penetrated into the tubular structure, so that the braided wires generate a local staggered stacking phenomenon, further stress on each part of the implant is uneven, the implant is extremely easy to be put into a sheath in an operation, and when the implant is released from the sheath, the implant is extremely easy to deviate and twist, so that normal release and recovery are influenced, and even the life of a patient is damaged.

Thirdly, no matter the silk weaving type cardiovascular implant 3 'or the tubular cardiovascular implant 2', a structure of additionally and independently increasing threads is needed, particularly, the silk weaving type cardiovascular implant 3 'also needs a welding closing structure 31', more welding spots are needed, so that falling risks are increased, in addition, the content of foreign matters in a body and the whole surface area are increased, and further, the risk of corrosion is increased.
