ABSTRACT:
A stent is formed from a hollow resilient tube shaped into a helical expanded configuration to form a substantially cylindrical prosthesis that is releasably attached to an actuation shaft for delivery to a treatment site. The stent is deliverable in a substantially linear configuration and deployed with internal fluid pressure, which is delivered through the actuation shaft, to return to the helical expanded configuration. Specifically, injection of a deployment fluid into the resilient tube that forms the stent causes the stent to revert or spring back from the substantially linear delivery configuration to the original helical configuration, and in some applications to dilate a vessel. A ring is attached to a distal end of the stent to couple the stent system to a guidewire for delivery through the vasculature.
