ABSTRACT:
The device, intended for insertion by means of a tube, comprises a supporting part having two branches attached to the front end in such a way that they spring apart when the device is pushed out of the tube into the uterus. At the end of each branch is a spherical occluding member, and at the rearward end of the supporting part is an eye through which a thread is looped. In order to achieve gentle sealing solely of the mouths of the Fallopian tubes, as well as to reduce production costs, the occluding members are of soft material and are flexibly connected to the associated branches, while the supporting part and the branches are made in one piece of a resilient but comparatively stiff material.
