<p>An implant (10) includes an expandable, flexible membrane (18) mounted over an expandable stent (10), which is releasably affixed to the balloon portion (14) of a catheter (16). The balloon (14) is inflated, thereby enlarging both the stent (12) and the membrane (18). Thereafter, the balloon (14) is deflated and the catheter (16) removed, leaving the stent (12) and membrane (18) in place. The implant (100) may also include an outer stent (106), surrounding a secured membrane (104).</p> |
