Abstract
An occlusion apparatus has a plastic ring with an opening at one point, encased in silicone, with a central opening of a first inside diameter, a silicone bladder in the circular, central opening, providing a hollow, semi-circular silicone ring, a mixture of sodium and potassium salts and polyacrylamide granules at a specific ration of materials enclosed in the silicone bladder, and two stirrups, one affixed on one side and the other opposite the first. The stirrups and the opening provide for spreading the apparatus by the stirrups to place the apparatus over a blood vessel, releasing the apparatus enclosing the blood vessel in the second inside diameter of the bladder, and wherein water passing through walls of the silicone bladder forms a hygroscopic gel that expands over time with further absorption of water, closing the second inside diameter of the silicone bladder, slowly occluding the blood vessel.
