Abstract

A system comprising a wrapping device that forms a ring of tensioned material by wrapping a material around an outer circumference of a tube encasement, and a cutting device that cuts through an entire cross-section of the ring of tensioned material, the tube encasement and a tube encased by the tube encasement, wherein the ring of tensioned material applies a first radial force onto the tube encasement and induces a second radial force from the tube encasement onto the tube.

First claim

The invention claimed is:

1. A hose comprising:
a tube;
a tube encasement encasing an outer circumference of said tube; and
a ring of tensioned material around an outer circumference of said tube encasement, wherein
said ring of tensioned material applies a first radial force onto said tube encasement and induces a second radial force from said tube encasement onto said tube, and
said hose comprises a cut surface that extends through an entire cross-section of said tube, said tube encasement and said ring of tensioned material.

2. The tube section of claim 1 , wherein said tensioned material is a shrinkable material.

3. The hose of claim 1 , wherein:
a product of said second radial force and a coefficient of friction between an inner circumference of said tube encasement and an outer circumference of said tube at a location of said second radial force is greater than 5 newton.

4. A hose comprising:
a tube;
a tube encasement encasing an outer circumference of said tube; and
a ring of bonded material at an outer circumference of said tube encasement,
wherein
said ring of bonded material forms a bond between said tube encasement and a tube encased by said tube encasement, and
said hose comprises a cut surface that extends through an entire cross-section of said tube, said tube encasement and said ring of bonded material.

5. The hose of claim 4 , wherein:
said ring of bonded material comprises a portion of said tube encasement that has been melted.

6. The hose of claim 4 , wherein:
said of bonded material comprises a bonding material that differs from and bonds a material of said tube encasement.

7. The hose of claim 1 , comprising:
a connector having an insert portion positioned in a lumen of said tube; and
an end piece that forms a bond between said end piece, said tube encasement, said tube and said insert portion.

8. The hose of claim 1 , wherein:
said tube has a tube wall selected from the group consisting of a corrugated tube wall, a tube wall having a spiral groove, and a smooth tube wall.

9. The hose of claim 1 , wherein:
said tube encasement comprises at least one of a braid of polyamide material and a braid of metal material.

10. The hose of claim 1 , wherein:
said tube is displaceable relative to said tube encasement over at least 80% of a length from a first end of said tube to a second end of said tube.

11. The hose of claim 1 , wherein:
said outer circumference of said tube encasement has a diameter of less than 15 mm.

12. A hose comprising:
a tube;
a tube encasement encasing an outer circumference of said tube; and
a ring of tensioned around an outer circumference of said tube encasement, wherein
said ring of tensioned material applies a first radial force onto said tube encasement and induces a second radial force from said tube encasement onto said tube,
said hose comprises a cut surface that extends through an entire cross-section of said tube, said tube encasement and said ring of tensioned material, and
said second radial force prevents longitudinal displacement of said tube encasement relative to said tube in a region of said ring of tensioned material.

13. The hose of claim 12 , wherein:
said tube is displaceable relative to said tube encasement over at least 80% of a length from a first end of said tube to a second end of said tube.

14. A hose comprising:
a tube;
a tube encasement encasing an outer circumference of said tube; and
a ring of bonded material at an outer circumference of said tube encasement, wherein
said ring of bonded material forms a bond between said tube encasement and a tube encased by said tube encasement, and
said hose comprises a cut surface that extends through an entire cross-section of said tube, said tube encasement and said ring of bonded material, and
said ring of bonded material prevents longitudinal displacement of said tube encasement relative to said tube in a region of said ring of bonded material.

15. The hose of claim 14 , wherein:
said tube is displaceable relative to said tube encasement over at least 80% of a length from a first end of said tube to a second end of said tube.

16. A hose comprising:
a tube;
a tube encasement encasing an outer circumference of said tube; and
a ring of bonded material at an outer circumference of said tube encasement, wherein
said ring of bonded material forms a bond between said tube encasement and a tube encased by said tube encasement,
said hose comprises a cut surface that extends through an entire cross-section of said tube, said tube encasement and said ring of bonded material, and
said ring of bonded material comprises a portion of said tube encasement that has been incited.
