Abstract

An intrauterine device for applying pressure to the walls of the uterine cavity includes a resilient body having an elongated member which includes a first end and a second end which are resiliently biased away from each other. The first end of the elongated member includes a first leg having a first end and a second end. The second end of the elongated member includes a second leg having a first end and a second end. A connection member is positioned between the first end of the first leg and the first end of the second leg. A first plug member is secured at the second end of the first leg and a second plug member is secured at the first end of the second leg. The first and second plug members are shaped and dimensioned for bearing against the walls of the uterine cavity as the elongated member spreads outwardly with the first end and the second end moving apart. A method for preventing conception within the uterine cavity is also disclosed.

First claim

The invention claimed is:

1. An intrauterine device for applying pressure to walls of a uterine cavity and an associated delivery apparatus, comprising:
a delivery apparatus composed of a small caliber longitudinal container;
the intrauterine device, comprising:
a resilient body including an elongated member composed of a shape memory material, the elongated member having a first end and a second end which are resiliently biased away from each other to generate a constant load when spanning a distance of 18 mm to 54 mm upon deployment within the uterine cavity, the first end of the elongated member including a first leg having a first end and a second end, and the second end of the elongated member including a second leg having a first end and a second end, wherein a connection member is positioned between the first end of the first leg and the first end of the second leg; and
a first plug member secured at the second end of the first leg and a second plug member secured at the second end of the second leg, the first and second plug members being shaped and dimensioned for bearing against the walls of the uterine cavity as the elongated member spreads outwardly;
wherein the intrauterine device is fully housed within the delivery apparatus prior to deployment with the first and second plug members staggered one in front of the other within the delivery apparatus.
