    Abstract: A releasable mechanism such as a cap is adapted for use with an access sheath having an elongate tube and a handle structure disposed at a proximal end of the tube. The releasable mechanism is sized and configured to fit the handle structure, which is shaped like the bell of a horn, to further facilitate use with surgical instrumentation. The releasable mechanism may operate as a separate cap that snaps onto the handle structure to provide access pathways to the sheath. The releasable mechanism may also be disposed at a proximal end of a surgical instrument to be introduced into the access sheath such that it may be interlocked with the sheath. In a method of manufacturing a kink-resistant sheath, a wire is initially coated with a plastic material, the coated wire is then wrapped around a mandrel forming a plurality of windings, and the wound coated wire is heated until the plastic material melts and bonds the windings to form a wire-reinforced sheath. The plastic material is preferably polyurethane but may be a thermoplastic, a thermoset or any plastic material having hard and/or soft durometer. The wound coated wire may be heated by capturing the windings within a shrink tube or compressing the windings in a mold and heating the windings until the sheath is formed. In another aspect of the invention, a mandrel is used as part of an extrusion process. In another aspect of the invention, another coating or outside layer could be formed over the spring reinforcement by dipping in a solvent based solution. In yet another embodiment of the invention, a braid such as a polyester braid may be used instead of or in addition to the coil spring to form a kink-resistant sheath.

    Abstract: A flexible, polymer, composite tube (1) adapted for transport of fluids such as hydrocarbons, e.g. oil and/or gas, and flexible enough to be coiled with a curvature radius as short as approximately 20 times its outer diameter. The flexible riser (1) comprises the following structural elements: an inner liner (2) of thermoplastic material, an intermediate reinforced, polymer, multi layer component (3), and an outer thermoplastic liner (4). The inner liner (2) is continuously bonded to the intermediate, multi layer component (3), which again is continuously bonded to the outer liner (4). A method for manufacturing the flexible tube (1) by welding or gluing is also described.
