Intravascular inflatable stent
First Claim
1. An inflatable stent comprising tightly, helically wound polymeric tubing forming tubing turns and having a proximal tubing end and a distal tubing end, forming a hollow column having an outer column diameter and an inner lumen extending along a stent axis from a proximal stent end to a distal stent end and having a lumen diameter, the distal tubing end being sealed and the proximal tubing end being adapted to accept an inflating fluid and having at least one flexible polymeric sizing strip laid against and adherent to the polymeric tubing from the region with the proximal stent end to the region of the distal stent end and where said at least one flexible polymeric sizing strip has a softening point below the softening point of the polymeric tubing.

Abstract
This invention is an intraluminal stent or graft suited for the noninvasive treatment of aneurysms, diseased blood vessels, and other bodily lumen. The stent is made up of polymeric tubing which is helically and tightly wound to produce a column having an open lumen from one end to the other. At the stent'"'"'s distal end, the tubing is sealed. At the stent'"'"'s proximal end, the stent is adapted to allow the introduction of fluid suitable for inflating the stent at the chosen vascular site. The stent coils adhere to each other or to one or more sizing strips which may be straight or helical in configuration, or the stent may be constructed to use both methodologies.
