1. (WO1999013801) BODY FLUID FLOW CONTROL DEVICE
Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

What is claimed is:
1. A body fluid flow control device comprising
a resilient seal of substantially annular configuration;
a frame extending within at least a portion of the resilient seal and including a passageway extending longitudinally through the frame and at least one longitudinally extending element having an insertion state and an anchoring state, the anchoring state being with the at least one longitudinally extending element outwardly of the insertion state, thereby expanding the portion of the resilient seal within which the frame extends, the passageway being inwardly of the at least one longitudinally extending element;
a valve body having bulk resilience and a passage therethrough resiliently biased closed by the bulk resilience and cornmunicating with the passageway;
a valve support about the valve body and attached to the valve body and to the resilient seal, the passage being in communication with the passageway extending longitudinally through the frame.
s 2. The body fluid flow control device of claim 1, the resilient seal further including a skirt extending at least partially over the at least one longitudinally extending element to form a peripheral seal.
3. The body fluid flow control device of claim 1 , the resilient seal further including a skirt extending within the at least one longitudinally extending element and o having a cuff over one end of each of the at least one longitudinally extending element to form a peripheral seal.
4. The body fluid flow control device of claim 1 , the resilient seal further including a skirt extending fully over the frame.
5. The body fluid flow control device of claim 1 , the passage having a 5 predetermined fluid opening pressure.
6. The body fluid flow control device of claim 5, the fluid opening pressure being about 0.2 psi to 3.0 psi for urinary incontinence.
7. The body fluid flow control device of claim 5, the fluid opening pressure being about 0.005 psi to 1.0 psi for intervascular placement.
0 8. The body fluid flow control device of claim 1, the passage being a single slit.
9. The body fluid flow control device of claim 8, the valve body having two substantially flat sides parallel to the slit which is located therebetween to effect a one-way valve.
10. The body fluid flow control device of claim 9, the resilient seal, the valve body and the valve support being one piece.
11. The body fluid flow control device of claim 9, the valve body extending into the passageway extending longitudinally through the frame.
12. The body fluid flow control device of claim 1, the resilient seal, the valve body and the valve support being one piece.
13. The body fluid flow control device of claim 1 , the valve support having a portion extending from the valve portion, the valve body being substantially a disk.
14. The body fluid flow control device of claim 1, the valve body being a disk, the at least one longitudinally extending element forming an expanded metal cylinder.
15. The body fluid flow control device of claim 1 further comprising
an elongate expander, the at least one longitudinally extending element defining a 5 concavity receiving at least a portion of the elongate expander.
16. The body fluid flow control device of claim 15, the elongate expander including a balloon at a distal end thereof with a passage extending substantially the length of the elongate expander.
17. The body fluid flow control device of claim 15, the elongate expander o including an outer sheath into which the resilient seal and the frame are positionable in the insertion state and a ram extending within the sheath to engage the frame in the passageway extending longitudinally through the frame.
18. The body fluid flow control device of claim 1, the at least one longitudinally extending element being heat recoverable with a transition temperature 5 range below a reasonable range of human body temperatures.
19. The body fluid flow control device of claim 1, the at least one longitudinally extending element being spring biased toward the anchoring state and being held in the insertion state by a release wire separable from the frame.
20. The body fluid flow control device of claim 1 further comprising 0 a flap attached to the valve body adjacent the passage and extending over the passage to restrict flow to one direction through the passage.
