Abstract
The proposed device for the occlusion of brain vessels comprises an occlusive bulb of an elastic material. Its thicker head portion accommodates a metal plug, while the tail portion contains a valve made of the material of the bulb itself, through which the tip of a catheter is introduced. The pear-shaped valve points inside the bulb, and its neck bears a spring element. When the bulb is drawn along an occluded vessel, with better maneuverability, the bulb's cavity is more reliably sealed after the catheter has been detached therefrom.
