Abstract
The present invention relates to an intraluminal thin film medical device particularly well suited for occlusion of an aneurysm, vessel side branch or dissection of a body lumen or duct, such as an artery or vein. The medical device has a thin film tube capable of being longitudinally stretched by the application of mechanical energy to achieve a smaller circumferential profile, and self-expand to the pre-stretched length and diameter upon release of the mechanical energy. To assist the thin film during expansion a plurality of slots are incised in the tube wall. The slots open and assist the thin film tube to longitudinally stretch, and substantially close when the thin film tube self-expands to the pre-stretched length and diameter.
Claims21
A medical device for occluding a body vessel comprising:
- a thin film tube capable of being longitudinally stretched by the application of mechanical energy to achieve a smaller circumferential profile, and self-expand to the pre-stretched length and diameter upon release of the mechanical energy;
- and
- a plurality of slots incised in the tube wall such the slots open and assist the thin film tube to longitudinally stretch, and substantially close when the thin film tube self-expands to the pre-stretched length and diameter.
A medical device for occluding a body vessel comprising:
- a thin film tube capable of being longitudinally stretched by the application of mechanical energy to achieve a smaller circumferential profile, and self-expand to the pre-stretched length and diameter upon release of the mechanical energy;
- and
- a plurality of apertures incised in the tube wall such the apertures to assist the thin film tube to longitudinally stretch.
A medical device for occluding a body vessel comprising:
- a thin film tube capable of being longitudinally stretched by the application of mechanical energy to achieve a smaller circumferential profile, and self-expand to the pre-stretched length and diameter upon release of the mechanical energy;
- and
- a stent attached to the interior surface of the thin metallic film.
