What is it indicated for?
All four sets of constriction rings, the Rejoyn Constriction Ring Kit, B-100, B-25, and B-10, are used to maintain penile rigidity in men with erectile dysfunction by restricting penile venous outflow after the patient has obtained an erection (either with the aid of a vacuum pump, or naturally). The constriction band is placed around the base of the erect penis to restrict the flow of venous blood leaving the penis.
