<p>Apparatus for treatment of a body passage includes an expandable implant (100), including first and second expandable sections (110) and a central section (120) between the expandable sections. A balloon (115) is contained within the expandable implant. An inflation tube (118) is coupled to inflate the balloon via at least first and second inflation ports (130, 135), which are respectively disposed within the first and second expandable sections of the implant, such that pressurization of the balloon via the inflation tube causes the first and second expandable sections of the implant to expand to a greater diameter than the central section.</p> |
