Abstract
The invention is directed to an improvement in stent delivery systems and method for releasably securing a stent onto an expandable member of a catheter. A deformable material is applied between the outer surface of the expandable member and the stent mounted thereon. The deformable material is affixed to an expandable member, similar to a dilatation balloon and is sufficiently compliant to be deformed by compressive engagement with the stent. The deformable material beneath the stent is compressed, projecting a portion of the material adjacent struts of the stent into a physical stop that impedes lateral movement of the stent relative to the balloon during delivery to the target site. The deformable material may be an adhesive or a curable compound in a cured or uncured state. The deformable material may be brought into releasably secure contact with the stent by shifting the stent toward the balloon, the balloon toward the stent, or both. Shifting the stent toward the balloon may include crimping the stent.
