METHOD AND APPARATUS FOR TREATING VEIN GRAFT LESIONS

A system for ablating material in vein grafts includes an ablation burr that is rotated by a driveshaft. The ablation burr preferably includes one or more channels, blades or other mechanisms that direct ablated material and liquid proximally and/or outwardly against a vessel wall. Aspiration is use...

Beschreibung
Zusammenfassung:	A system for ablating material in vein grafts includes an ablation burr that is rotated by a driveshaft. The ablation burr preferably includes one or more channels, blades or other mechanisms that direct ablated material and liquid proximally and/or outwardly against a vessel wall. Aspiration is used to remove ablated material and liquid from the treatment area. Finally, methods for treating vein grafts and original native arteries are disclosed. L'invention concerne un système d'ablation de matière dans des greffons veineux comprenant une fraise d'ablation dont la rotation est entraînée par un arbre. La fraise d'ablation comprend de préférence une ou plusieurs voies, lames ou autres mécanismes dirigeant la matière et le liquide ablatés vers l'extrémité proximale et/ou vers l'extérieur contre une paroi vasculaire. On utilise l'aspiration afin d'éliminer de la zone de traitement la matière et le liquide ablatés. L'invention concerne enfin des méthodes de traitement de greffons veineux et d'artères natives.
