Stent aneurysm treatment system and method |
摘要 |
<p>A vascular stent for opening blood vessel occlusions and for providing support to damaged areas of blood vessel sites includes a proximal end defining a first lumen opening. The helical stent is constructed from a resilient material and has a body portion extending from the proximal end to define a lumen. A distal end defines a second lumen opening a predetermined axial distance from the first lumen opening. The stent is maintained in a stretched linear state when in a catheter for delivery to a vascular site, and resiliently expands into a relaxed helical shape when released from the catheter. Various embodiments of the present invention are disclosed, including a stent made of a wire having a flattened cross-section, a helical wire stent having a flat ribbon to span between adjacent loops of wire, multiple intertwined stents in the same blood vessel. A preferred embodiment of the present invention involves treating an aneurysm formed at a vessel branching by arranging multiple helical wire stents in each vessel.
