Abstract: A method for occluding a blood vessel has steps for encasing a semi-rigid, circular plastic ring, open at one point, in silicon material, forming a bladder along an inside diameter of the silicon material, placing a mixture of sodium and potassium salts and polyacrylamide granules in the bladder, closing and sealing the bladder, forming a pair of opposed stirrups on an outside diameter of the silicon material, spreading the encased plastic ring by the stirrups accomplishing an opening through the ring of an extent enabling the ring to be placed over a blood vessel, placing the encased plastic ring over the blood vessel, releasing the stirrup, allowing the ring and bladder to close around the blood vessel, such that the bladder, constrained by the ring from expanding outward, absorbing moisture by osmosis over time, expands inward, and over a time t fully occludes the blood vessel.

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.

Abstract: An apparatus for treating the brain, comprises a first fluid delivery device including a distal end sized and shaped for placement at a first target site between a dura mater and a pia mater of the brain, the first fluid delivery device including a first fluid lumen extending to a first outlet port in the distal end to deliver fluids to a first target location and a first microelectrode mounted within the distal end of the first fluid delivery device for movement between an insertion position in which a first distal tip of the first microelectrode is received within the first fluid delivery device and a deployed position in which the first microelectrode extends out of the first fluid delivery device with the first distal tip thereof penetrating the pia mater to a first electrode target position in the cerebral cortex.
