A device for delivering a plug () in a vessel of a human or animal body, includes an inserter provided with a guiding channel () and elements for urging the plug into the channel (), characterized in that the channel () is adapted for radially compressing the plug during the displacement thereof towards the distal end of the channel (). The compression of the plug () is carried out only a few seconds before its placement while respecting the integrity thereof. The elasticity characteristics of the plug () are thus fully preserved. The present device can be used in open surgery or endoscopy, mainly in vascular surgery.

Method for delivering an occlusion plug

A blood vessel such as a varicose vein is removed using a semi-rigid rod attached to a flexible thread. The thread is passed through the vein using the rod, which can then be removed. An end of the vein is affixed at a point between the ends of the thread, for example the midpoint. By pulling on the thread, the end of the vein is drawn back into the lumen of the vein, and the vein is progressively turned inside out. A stop can be fixed to the thread slightly beyond the point at which the vein is affixed to the thread, and prevents slipping along the thread. The thread can be at least twice as long as the vein, and alternately pulled in opposite directions.
