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.
Claims39
A medical device, comprising:
- a membrane implantable in a body lumen and invertably deformable between a first position and a second position,
- wherein the membrane is invertible in response to the direction of fluid flow through the lumen.
A medical system, comprising:
- a plurality of membranes, each membrane implantable in a body lumen and invertably deformable between a first position and a second position,
- wherein the membrane is invertible in response to the direction of fluid flow through the lumen.
A method, comprising:
- positioning at least one membrane in a body lumen, each membrane invertably deformable between a first position and a second position,
- wherein the at least one membrane is invertible in response to the direction of fluid flow through the lumen relative to the membrane in the first position.
A method of controlling flow in a body lumen, the method comprising:
- invertably deforming a membrane between a first position and a second position,
- wherein the membrane is invertible in response to the direction of fluid flow through the lumen.
