A device and method for reversibly occluding a body duct, (41) such as the vas deferens, to prevent fluid flow therethrough. The device comprises two spaced flexible plugs (12, 14) connected to each other by a flexible connecting member, (16) such as a suture or other filament. The plugs are of size so as to be snugly received by the lumen (44) of the body duct at implantation without exerting excessive pressure therein. The device is preferably implanted in the duct by insertion of each plug through a respective puncture hole (46) in the wall (42) of the duct, with a portion of the connecting member being retained externally of the duct to prevent migration of the plugs.
