Endovascular stents capable of being cut from a flat piece of material are described. The endovascular stents may be bioabsorbable, multilayered and may have structural configurations allowing them to maintain low profiles in vivo. Methods of manufacturing endovascular stents and methods of using endovascular stents are also described.

Endovascular stents

A self-centering umbrella-type septal closure device which includes a proximal and distal occluder each having a plurality of arms supporting the occlusion shells. Each of the proximal and distal support arms have at least three coils any one or more of which is secured by a centering mechanism so as to control the positioning of the closure device so that it is centered about a defect.

A system for introducing a stent into a patient at a site of stenosis is disclosed. The system comprises a balloon catheter having a stent surrounding the balloon portion of the catheter. At least one stent-retaining means is located adjacent to at least one end of the balloon to retain the stent in position on the catheter until the balloon is inflated. Upon inflation of the balloon, the stent is expanded and the retention means releases the stent. The balloon is then deflated and the catheter is removed from the patient, leaving the expanded stent in place.
