Methods and devices for providing a minimally-invasive placement of a mechanical structure for reducing the volume of a hollow body organ. Anchors may be secured within the hollow body organ and then cinched together using a tensioning member to form a stricture within the hollow body organ. In another embodiment a tensioning member may be threaded along the hollow body organ and then cinched to reduce the volume. The strictures may be placed anywhere within the hollow body organ, and more than one stricture may be formed within the hollow body organ.

A capillary has a face surface 13 formed at the tip end thereof so that the face surface 13 inclines toward the center thereof so as to have a tapered shape, and has a through hole 11 formed therethrough so as to permit wire to be placed therethrough so that the through hole 11 has an opening 12 at the center of the face surface 13. The inclination angle θ of the face surface 13 relative to the plane perpendicular to the axis of the capillary and including the opening 12 of the through hole 11 is in the range from 4° to 15°, and the height h of the face surface 13 along the axis of the capillary is equal to or greater than the thickness of the wire 2.

In a process for producing a biocompatible stent, a tubular substrate of the stent adapted for diametric expansion has a layer of a noble metal oxide formed over at least the outer surface of greater diameter of the substrate, the substrate being composed of a metal or an alloy thereof that is non-noble or less-noble than the layer's noble metal. An interface region adapted to prevent corrosion and to provide a firm bond between the surface of the substrate and the noble metal oxide layer is established, at least in part, by forming the noble metal oxide layer with a progressively varying concentration of noble metal-to-oxide with depth of the layer such that a surface of pure noble metal and negligible oxide of the layer is in closest proximity to the surface of the substrate. In one embodiment of the process, the interface region is established by forming the surface of pure noble metal and negligible oxide thereof in direct contact with the metal or alloy of the substrate surface. In another, the interface region is established by first creating an oxide of the substrate metal or alloy thereof at the substrate surface, and then forming the noble metal oxide layer as above, but in contact with the substrate metal or alloy oxide. Alternatively, the noble metal oxide layer has no progressively varying concentration but simply overlies an oxide of the substrate metal or alloy.

A thermoplastic elastomer composition which, when used for the inner tube and / or outer cover of a hose, can improve the hose flexibility at an ordinary temperature and low temperature, oil resistance, and cold resistance and can reduce the production costs since it does not require a vulcanization step and a hose having said properties using this elastomer composition for its inner tube and / or outer cover and a process and apparatus for the production thereof.
