1. A method for providing a polymeric coating on a surface of a body lumen which comprises the steps of:

  • a) providing a device which comprises;

    i) an elongated shaft including at least one occlusion element for occluding the body lumen and an injection lumen for injecting a fluent prepolymer material into a space defined at least at one end by the occlusion element; and

    ii) an optical emitter positioned in the space defined at least at one end by the occlusion element;

    b) positioning said at least one occlusion element at a desired location in the body lumen;

    c) positioning the optical emitter at a treatment site;

    d) actuating said at least one occlusion element to define a treatment space;

    e) injecting a fluent prepolymer into the treatment space;

    f) directing light through the optical emitter into the prepolymer to photopolymerize at least a portion of the prepolymer;

    g) deactuating said at least one occlusion element; and

    ,h) withdrawing the device from the body lumen, thereby leaving a layer of polymeric material on at least a surface of the body lumen.
