The carcass arrangement provides skeletal strength to the hose assembly against radial forces. The carcass arrangement has a plurality of interconnecting strips forming convoluted joints between the strips. The convoluted joints have an inner lip and an outer lip at opposite ends of the strips; and the carcass further comprises a plurality of channels formed along an entire length of first and second sides of the strips, the channels creating at least one fluid passage in each of the convoluted joint forming the carcass for the passage of fluids between the inner and outer diameters. ## Claims ### Claim 1 A method of manufacturing a hose assembly comprising the steps of: passing a single metal strip through a die to form a plurality of channels on the metal strip; winding said strip on a mandrel to create a plurality of convolutions, each convolution of the plurality of convolutions having first and second ends; fastening adjacent convolutions together at an interlocked joint to form a continuous carcass, wherein a first end of a convolution of the plurality of convolutions interlocks with a second end of an adjacent convolution to form an interlocked joint; surrounding said continuous carcass with a sealing sheath; surrounding said sealing sheath with at least one braided layer; and surrounding said at least one braided layer with an external sheath. ### Claim 2 (depends on 1) The method of manufacturing a hose assembly of claim 1, wherein the die is a forming die that embosses the plurality of channels on said metal strip. ### Claim 3 (depends on 2) The method of claim 2, wherein said plurality of channels are transverse to the first and second ends of said strip. ### Claim 4 (depends on 2) The method of claim 2, wherein said plurality of channels are perpendicular to the first and second ends of said strip. ### Claim 5 (depends on 2) The method of manufacturing a hose assembly of claim 2, wherein embossing the plurality of channels on said metal strip comprises defining a plurality of adjacent ridges and valleys on first and second sides of said metal strip. ### Claim 6 (depends on 5) The method of manufacturing a hose assembly of claim 5, wherein the defining a plurality of adjacent ridges and valleys on first and second sides of said metal strip comprises defining the plurality of adjacent ridges and valleys continuously from the first end to the second end of said convolutions. ### Claim 7 (depends on 2) The method of manufacturing a hose assembly of claim 2, wherein the passing step further comprises defining a plurality of adjacent ridges and valleys along an entire length of said metal strip. ### Claim 8 (depends on 2) The method of manufacturing a hose assembly of claim 2, the fastening adjacent convolutions together comprising creating at least one fluid passage in each of said interlocked joint utilizing the channels. ### Claim 9 (depends on 1) The method of manufacturing a hose assembly of claim 1, wherein the die is a punching die that forms a plurality of spaced notches on said metal strip. ### Claim 10 (depends on 9) The method of manufacturing a hose assembly of claim 9, wherein said spaced notches are at least one of arcuately shaped, elliptical shaped, and rectangular shaped. ### Claim 11 (depends on 1) The method of manufacturing a hose assembly of claim 1, wherein in the step of passing said strip through the die a substantially S-shaped ribbon is formed having inner and outer body portions and inner and outer lips that extend from the inner and outer body portions, respectively, and wherein in the step of winding said strip on the mandrel the inner lip is interfitted with the outer lip. ### Claim 12 (depends on 1) The method of manufacturing a hose assembly of claim 1, the winding said strip on a mandrel to create a plurality of convolutions step further comprises forming an inner lip and an outer lip at the first and second ends of said convolutions. ### Claim 13 (depends on 12) The method of manufacturing a hose assembly of claim 12, wherein creating a plurality of convolutions comprises forming substantially S-shaped convolutions having an inner body portion and an outer body portion, said inner and outer lips extending from said inner and outer body portions, respectively. ### Claim 14 A method of manufacturing a hose assembly comprising the steps of: passing a single metal strip through a die to form a plurality of channels extending from a first end to a second end of the strip; winding said strip on a mandrel to create a plurality of convolutions, each convolution of the plurality of convolutions having first and second ends, wherein the plurality of channels extend from the first end to the second end; fastening adjacent convolutions together at an interlocked joint to form a continuous carcass having an inner and outer diameter about a central axis, wherein a first end of a convolution of the plurality of convolutions interlocks with a second end of an adjacent convolution; surrounding said continuous carcass with a sealing sheath; surrounding said sealing sheath with at least one braided layer; and surrounding said at least one braided layer with an external sheath. ### Claim 15 (depends on 14) The method of manufacturing a hose assembly of claim 14, wherein in the step of passing said strip through the die a substantially S-shaped ribbon is formed having inner and outer body portions and inner and outer lips that extend from the inner and outer body portions, respectively, and wherein in the step of winding said strip on the mandrel the inner lip is interfitted with the outer lip, wherein the interfitted inner and outer lips create at least one fluid passage between the inner and outer diameters in each of said interfitted inner and outer lips utilizing the channels. ### Claim 16 (depends on 14) The method of manufacturing a hose assembly of claim 14, wherein forming the plurality of channels on said metal strip comprises defining a plurality of adjacent ridges and valleys on first and second sides of said metal strip that extend continuously from the first end to the second end of said convolutions. ### Claim 17 (depends on 14) The method of manufacturing a hose assembly of claim 14, wherein forming the plurality of channels on said metal strip comprises defining a plurality of adjacent ridges and valleys along an entire length of said metal strip. ### Claim 18 (depends on 14) The method of claim 14, wherein said plurality of channels are traverse to the first and second ends of said strip. ### Claim 19 A method of manufacturing a hose assembly comprising the steps of: embossing a metal strip with a plurality of channels comprising adjacent ridges and valleys, the plurality of channels extending continuously from a first end to a second end of the strip; passing a single metal strip through a die to form a substantially S-shaped ribbon having inner and outer body portions and inner and outer lips that extend from the inner and outer body portions, respectively, the lips defining the first and the second end; winding said strip on a mandrel to create a plurality of convolutions, each convolution of the plurality of convolutions having the first and second ends, wherein the plurality of channels extend from the first end to the second end, wherein during the winding the inner lip is interfitted with the outer lip, wherein the interfitted inner and outer lips create at least one fluid passage between the inner and outer diameters in each of said interfitted inner and outer lips utilizing the channels, the interfitting forms a continuous carcass having an inner and outer diameter about a central axis, wherein the first end of a convolution of the plurality of convolutions interlocks with a second end of an adjacent convolution;
