Abstract
An embolic coil conveying device and a preparation method thereof are disclosed. The embolic coil conveying device includes a pusher and an embolic coil. A distal end of the pusher and a proximal end of the embolic coil are connected to serve as a detachment section. A stretch-resistant thread is disposed in the embolic coil. The stretch-resistant thread is fixed at the proximal end of the embolic coil. A conductive wire is disposed in the pusher. The stretch-resistant thread is connected to the conductive wire. Compared with the prior art, the present invention has the advantages that the stretch-resistant thread is fixed at the proximal end of the embolic coil, so that the stretch-resistant thread is connected to the conductive wire, thereby reducing the length of the detachment section, making the detachment section more flexible, and avoiding kick-out of a microcatheter due to release of the embolic coil.
