Intrauterine fallopian tube occlusion device
An intrauterine device for occluding orifices of fallopian tubes includes a resilient body having an elongated member with a first end and a second end. The elongated member further includes a first leg ending with the first end of the elongated member, a second leg ending with the second end of the elongated member and a connection member positioned therebetween. A first orifice plug is secured at the first end of the elongated member and a second orifice plug is secured at the second end of the elongated member. The first and second orifice plugs 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.
1. An intrauterine device for positioning at or within orifices of fallopian tubes, the intrauterine device comprising:
a resilient body including an elongated member having a first end and a second end, the elongated member further including a first leg ending with the first end of the elongated member, a second leg ending with the second end of the elongated member and a connection member positioned therebetween;
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 and second orifice plugs being shaped and dimensioned to seat within the fallopian tubes as the elongated member spreads outwardly with the first end and second end moving apart;
wherein the resilient body extends to spread the first orifice plug and the second orifice plug, when deployed within respective orifices of the fallopian tubes, from 18 mm to 54 mm, and applies a substantially constant load of between 15 and 30 grams.
2. An intrauterine device for positioning at or within orifices of fallopian tubes, the intrauterine device comprising:
a resilient body including an elongated member having a first end and a second end, the elongated member further including a first leg ending with the first end of the elongated member, a second leg ending with the second end of the elongated member and a connection member positioned therebetween;
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 and second orifice plugs being shaped and dimensioned to seat within the fallopian tubes as the elongated member spreads outwardly with the first end and second end moving apart;
wherein a substantially constant load of between 15 and 30 grams is applied by the resilient body.
3. An intrauterine device for positioning at or within orifices of fallopian tubes, the intrauterine device comprising:
a resilient body including an elongated member having a first end and a second end, the elongated member further including a first leg ending with the first end of the elongated member, a second leg ending with the second end of the elongated member and a connection member positioned therebetween;
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 and second orifice plugs being shaped and dimensioned to seat within the fallopian tubes as the elongated member spreads outwardly with the first end and second end moving apart;
wherein upon release of the intrauterine device within the uterine cavity (a) the first and second orifice plugs first move outwardly due to stored outward bias in the elongated member, (b) the first and second orifice plugs then move upwardly within the uterine cavity, (c) the first and second orifice plugs then move into contact with respective opposed walls of the uterine cavity and (d) the first and second orifice plugs apply pressure to respective opposed walls of the uterine cavity at substantially constant load of between 15 and 30 grams and ride up the opposed walls of the uterine cavity directing the first and second orifice plugs to respective orifices of fallopian tubes until the first and second orifice plugs seat within the fallopian tubes.
4. The intrauterine device according to claim 3 , wherein the resilient body extends to spread the first orifice plug and the second orifice plug, when deployed within respective orifices of the fallopian tubes, from 18 mm to 54 mm.
5. The intrauterine device according to claim 3 , wherein a substantially constant load is applied by the resilient body when the first orifice plug and the second orifice plug are spaced within the range of 18 mm to 54 mm.
