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 invertibly 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.
Claims10
A medical device, comprising:
- a first frameless membrane not supported by a frame having a first membrane sealing surface;
- and
- a second frameless membrane not supported by a frame having a second membrane sealing surface, the first frameless membrane and the second frameless membrane implantable in a body lumen and deformable between a first position under antegrade fluid flow and a second position under retrograde fluid flow, where in the second position the first membrane sealing surface and the second membrane sealing surface meet to resist fluid flow, and where the first membrane sealing surface and the second membrane sealing surface are formed of a material different from and more flexible than other portions of the first frameless membrane and the second frameless membrane.
