A venous valve is disclosed for implantation in and selectively restricting the outflow of blood from a penile vein to aid a user in achieving and/or maintaining an erection. The venous valve includes a self-expanding stent framework defining a blood flow lumen there through. The self-expanding stent framework is constructed to recoil from a radially compressed configuration in which the blood flow lumen is narrowed to restrict blood flow through the venous valve to a radially expanded configuration in which the blood flow lumen is fully open to permit unrestricted blood flow through the venous valve. A recoil delay component is attached to the self-expanding stent framework for slowing the recoil of the self-expanding stent framework to thereby provide an extended time period during which the blood flow lumen is narrowed and blood flow through the venous valve is restricted.
