Implant comprising an expandable section

An implant, adapted to post-operatively and non-invasively be adjustable by a remote control or a push bottom under the skin adapted to activate an implanted control unit of the powered implant, comprising at least one expandable section;

• wherein said implant is adapted to be adjustable between a first at least partly collapsed state, in which said expandable section is at least partly collapsed, and a second expanded state, in which said expandable section is expanded,
• wherein an outer surface of said expandable section at least partly comprises a surface structure having elevated areas alternating with lowered areas,
• wherein said expandable section is adapted to have, in said first collapsed state,
• a first distance between adjacent elevated areas sufficiently extended to prevent growth of fibrotic tissue from directly interconnecting adjacent elevated areas to an extent that compromises the adjustability between a first collapsed and a second expanded state of said implant said first distance being greater than about 1.0 mm, and wherein the implant further comprising
• connecting areas between adjacent elevated and lowered areas, further adapted to have, in said first collapsed state,
• a second distance between adjacent connecting areas sufficiently extended to prevent growth of fibrotic tissue from directly interconnecting adjacent connecting areas to an extent that compromises the adjustability between a first collapsed and a second expanded state of said implant said second distance being greater than about 1.0 mm,
• wherein said implant, further comprising;
• at least one sealed hollow space of the expandable section adapted to receive a fluid,
• a reservoir adapted to hold said fluid,
• a powered pump, adapted to move fluid from said reservoir to said hollow sealed space to create pressure in said chamber, and
• wherein the outer surface of the expandable section is adapted to be filled with a pressurized fluid, comprises said elevated areas alternating with lowered areas.
