An intrauterine device for actively occluding the orifices of the fallopian tubes using the shape of the uterine cavity as a guide to proper positioning of the intrauterine device, the intrauterine device comprising: a resilient body shaped as an elongated member having a first end and second end; a first orifice plug secured at the first end of the elongated member and a second orifice plug secured at the second end of the elongated member; the first end of the elongated member is composed of a first leg and the second end of the elongated member is composed of a second leg, and wherein the first leg includes a first end and second end, and the second leg includes a first end and second end, and the first ends (38, 42) of the respective first and second legs (34, 36) are respectively connected by a connection, while the second ends (40, 44) of the first and second legs (34, 36) are respectively free and are provided with the respective first and second orifice plugs (20, 22), the first leg and the second leg are angularly oriented relative to each other such that the elongated member is substantially V-shaped when the first leg and the second leg are allowed to move away from each other based upon the outward bias inherent in the connection and the resilience of the first leg and the second leg causing an outward bow in the first leg and the second leg when they are unrestrained, the first leg and the second leg forming a maximum angle of approximately 150 degrees relative to each other when entirely unrestrained; wherein the first and second orifice plugs (20, 22) are shaped and dimensioned to seat at the orifices of the fallopian tubes or within the fallopian tubes as the elongated member spreads outwardly with the first end and second end moving apart until the first and second orifice plugs (20, 22) of the intrauterine device distally reach respective walls of the uterine cavity, ride up the walls of the uterine cavity and seat at the orifices of the fallopian tubes or within the fallopian tubes. a resilient body shaped as an elongated member having a first end and second end; a first orifice plug secured at the first end of the elongated member and a second orifice plug secured at the second end of the elongated member; the first end of the elongated member is composed of a first leg and the second end of the elongated member is composed of a second leg, and wherein the first leg includes a first end and second end, and the second leg includes a first end and second end, and the first ends (38, 42) of the respective first and second legs (34, 36) are respectively connected by a connection, while the second ends (40, 44) of the first and second legs (34, 36) are respectively free and are provided with the respective first and second orifice plugs (20, 22), the first leg and the second leg are angularly oriented relative to each other such that the elongated member is substantially V-shaped when the first leg and the second leg are allowed to move away from each other based upon the outward bias inherent in the connection and the resilience of the first leg and the second leg causing an outward bow in the first leg and the second leg when they are unrestrained, the first leg and the second leg forming a maximum angle of approximately 150 degrees relative to each other when entirely unrestrained; wherein the first and second orifice plugs (20, 22) are shaped and dimensioned to seat at the orifices of the fallopian tubes or within the fallopian tubes as the elongated member spreads outwardly with the first end and second end moving apart until the first and second orifice plugs (20, 22) of the intrauterine device distally reach respective walls of the uterine cavity, ride up the walls of the uterine cavity and seat at the orifices of the fallopian tubes or within the fallopian tubes.
