AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
Claims 1-18 are cancelled.
1. A hose comprising:
(a) a flexible elongated outer tube having a first end and a second end, an interior of said outer tube being substantially hollow;
(b) a flexible elongated inner tube formed of an elastic material and having a first end and a second end, an interior of said inner tube being substantially hollow;
(c) a first coupler secured to said first end of said inner and said outer tubes;
(d) a second coupler secured to said second end of said inner and said outer tubes; and
(e) said first coupler adapted to couple said hose to a source of pressurized fluid, said second coupler adapted to couple said hose to a fluid flow restrictor, whereby said fluid flow restrictor is adapted to create an increase in fluid pressure between said first coupler and said second coupler within said hose to expand said elongated inner tube longitudinally along a length of said inner tube and laterally across a width of said inner tube thereby substantially increasing a length of said hose to an expanded condition and wherein said hose is adapted to contract to a substantially decreased or relaxed length when there is a decrease in fluid pressure between said first coupler and said second coupler;
wherein the flexible elongated inner tube provides a biasing force sufficient to retract the hose from the expanded condition to the relaxed length when fluid pressure between said first coupler and said second coupler is equal to or less than ambient pressure.
