Abstract: A method of forming a plurality of hollow fibers includes the step of providing an elongated flexible substantially continuous fiber and coating an outer surface of the fiber with a hollow fiber material. The hollow fiber material is cured or hardened. A gap is created between the outer surface of the support fiber and the inner surface of the coating layer defined thereon. The coated support fiber is cut into a plurality of fiber segments each having exposed ends. The support fiber segments are removed from the coating layer so as to provide a plurality of hollow fibers.

Abstract: The present invention provides inventive hollow fibers having defined gas permability characteristics. Hollow fibers of the present invention are characterized by a PMPCO2 greater than 30,000 Barrer*MPa. Curable compositions and silicone elastomers produced by curing the curable compositions are provided by the present invention. Compositions and methods for making the hollow fibers and devices incorporating them are provided by the present invention.

Abstract: A method of forming hollow fiber bundles includes the step of providing a mat having a plurality of hollow fibers forming a weft and a plurality of soluble fibers forming a warp. Each hollow fiber extends between a first side and an opposed second side of the mat. The mat is bundled so as to form a bundle with the first side of the mat defining a first end of the bundle and the second side of the mat defining a second end of the bundle. At least a portion of the bundle is potted so as to substantially fix a position of the hollow fibers relative to each other. The soluble fibers are at least partially dissolved so as to remove the soluble fibers from the bundle.

Abstract: A thin walled microtube is formed by providing a continuous elongated member having an outer surface. The member is at least partially formed of a water soluble material. A coating material is provided. The coating material may be a silicone compound that is curable such that the coating material cures into a substantial non-porous silicone. The outer surface of the elongated member is coated with a coating material so as to form a substantially uniform and continuous layer of coating material on the outer surface. The layer of coating material is cured so as to form a substantial uniform and continuous layer of substantially non-porous silicone on the outer surface. The elongated member is at least partially dissolved using water and purged from the silicone layer, such that an elongated tube of substantially non-porous silicone is formed.
