ABSTRACT:
Embodiments of the invention provide for a unidirectional flow valve. For example, embodiments of the invention include a method of providing a unidirectional flow valve to a vein that include folding a first portion of a vein over an adjacent second portion of a vein and engaging at least two opposing areas of the second portion of the vein to adjacent areas of the first portion of the vein. The at least two opposing walls of the second portion of the vein define the unidirectional flow valve. At least one support device may be inserted into the folded valve region of the vein to maintain the folded configuration of the valve.
