Abstract
An implantable valve having a valve element or leaflet and a base that is attachable to a vessel wall using a connector such as a screw, pin or a staple. The valve can be implanted using a catheter to position the valve in a desired location and drive the connector into the vessel wall. The valve can be used as a venous valve to control blood flow within the veins, arteries, heart or the aorta of a patient.

25. A valve comprising:
-
a base;
a connector that attaches the base to a lumen surface region; and
a tubular wall attached to the base, the tubular wall having a distal end with a distal opening and a proximal end with a proximal opening such that fluid flow from the distal end to the proximal end forces the tubular wall into an open position and fluid flow from the proximal end to the distal end forces the tubular wall into a closed position. - View Dependent Claims (26, 27, 29, 30, 31, 32, 33, 34, 35, 36, 37)
