Abstract
Abstract Method and apparatus implementing and using techniques for controlling flow in a body lumen, including use of an implantable medical device. The device includes a membrane implantable in a body lumen and invertably deformable between a first position and a second position. The membrane is invertible in response to the direction of fluid flow through the lumen and can be deformable by fluid flow in the body lumen.
