Patent ID: 7621276

Claim:
An occlusion device for actively occluding fallopian tubes using the shape of a uterine cavity as a guide to proper positioning of the occlusion device, the occlusion device comprising: a resilient body composed of a shape memory alloy, the 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, and 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; and the first leg and the second leg are angularly oriented relative to each other such that the first leg and the second leg are allowed to move away from each other based upon the outward bias inherent in the resilient body 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; wherein the first and second orifice plugs are shaped and dimensioned to seat at the orifices of the fallopian tubes or within the fallopian tubes when the elongated member spreads outwardly with the first end and second end moving apart until the first and second orifice plugs of the occlusion device distally reach respective walls of the uterine cavity, ride upon the walls of the uterine cavity and seat at the orifices of the fallopian tubes or within the fallopian tubes; and wherein the first and second orifice plugs are selectively separated from the resilient body.
