1. A fluid delivery system comprising:

  • a fluid source containing a fluid; and

    a conduit to conduct said fluid from said fluid source to a desired location on a body of a patient and including;

    a tubular member including first and second conduit walls having parallel longitudinally extending, transversely spaced edges joined together in fluid-sealing relation; and

    a seam line defined in said tubular member to form first and second lumens within said tubular member that are attached to each other along a side edge of said lumens, each lumen having interior and exterior surfaces and longitudinally spaced first and second open terminal ends but is otherwise fluid sealed along its length, and said seam line extending within said tubular member between said attached first and second lumens from said first open terminal end of said attached lumens to said second open terminal end of said attached lumens;

    wherein said interior surfaces, in the absence of applied pressure therebetween, are normally disposed substantially flush against one another, each of said first and second lumens being responsive to pressure applied between interior surfaces such that said interior surfaces expand away from one another;

    wherein said first lumen is configured to conduct said fluid from said fluid source to said desired location and said first open terminal end of said first lumen serves as an inlet and is configured to attach to said fluid source to receive fluid therefrom and said second open terminal end of said first lumen serves as an outlet and is configured to deliver said fluid to said desired location.
