International Classification:

B65H 81/00

US Classification:

156175, 156169, 156173, 1563082, 1563096

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.

US Classification:

4273855, 4273881, 4273935, 4273936

Abstract:

The present invention relates to anaerobically curable compositions, methods of preparation and methods of use that provide enhanced physical properties when cured in contact with untreated inactive surfaces. The compositions which include isobornyl acrylate, isobornyl methacrylate or combinations thereof in combination with a multi(meth)acrylate and a free-radical initiator, may be used without the addition of a transition metal catalyst.

International Classification:

B65H 81/00
B32B 37/00

US Classification:

156149, 156171

Abstract:

A method of manufacturing a kink resistant sheath includes the steps of coating a wire with a plastic material to form an inner tube, placing a braid over the inner tube, applying a spring reinforcement over the braid and applying a second layer of plastic material over the assembly to form an outer tube of a braided reinforced sheath. The plastic material is preferably polyurethane but may be a thermoplastic, thermoset or any plastic material having hard and/or soft durometer.
