Methods and apparatus for delivering prostheses to body lumens, such as stents and grafts to blood vessels, utilize a delivery device (10) which carries one or more linearized elements (40). The linearized elements (40) assume non- linear configurations, particularly helical configurations, when advanced and released from the delivery device (10). By selectively controlling the length and/or number of elements (40) delivered from the delivery device (10), extended and disseminated disease within the body lumens may be effectively treated.

Procédés et dispositifs servant à poser des prothèses dans des lumières corporelles, telles que des extenseurs et des greffes de vaisseaux sanguins, ce qui consiste à mettre en application un dispositif de mise en place portant un ou plusieurs éléments rectilignes. Ces éléments rectilignes prennent des configurations non linéaires, en particulier, des configurations hélicoïdales, quand on les place vers l'avant et qu'on les libère du dispositif de mise en place. Le contrôle sélectif de la longueur et/ou du nombre d'éléments mis en place par le dispositif permet de traiter efficacement des troubles étendus et disséminés à l'intérieur des lumières corporelles.
