Patent ID: 8727231

Claim:
A method for fabricating a sealed microfluidic conduit assembly, the method comprising: forming a joint through which a first conduit fluidly communicates with a second conduit by bringing a first axial end section of the first conduit into contact with a second axial end section of the second conduit, wherein a layer of malleable material coaxially surrounds the first axial end section, a jacket coaxially surrounds the layer of malleable material, the first axial end section and the second axial end section, and the layer of malleable material has a lower hardness than the first conduit, the second conduit and the jacket; and compressing the layer of malleable material against the joint to fluidly seal the joint, by applying a radial force to an outer surface of the jacket at an axial distance from the joint, wherein the layer of malleable material forms a fluidic seal.
