An endoluminal occluding device consisting of a conical-shaped structure which is attached to a threaded central tubular element is capable of occluding a body lumen immediately after placement. When deployed within a body lumen, such as a fallopian tube, the conical-shaped structure extends radially outward from the central tubular element, thereby acutely occluding the body lumen, and, in the case of the fallopian tubes, preventing conception. As the acute occlusion device is being implanted into a body lumen, it is rotated, as the screw threads, which embed into the body lumen wall, advance the device within the body lumen to the desired located. Once implanted and deployed into a body lumen, the acute occlusion device provides immediate occlusion of the body lumen. A proximal anchor prevents the endoluminal device from migrating into the body lumen once it has been deployed.
