1. A method of therapeutic intervention for treatment of a patient in need of such treatment, said method comprising:
- introducing to a physiological locus of said patient a balloon formed from two vacuum thermoformed half-sections of a multilayer film comprising;
(A) a layer of sealing film, having main top and bottom surfaces; and
(B) at least one layer of thermoplastic polymer film, disposed along least one of the main top and bottom surfaces of the sealing film;
wherein the sealing film has a composition and thickness imparting gas barrier character to the multilayer film and wherein the at least one layer of thermoplastic polymer film alone lacks such gas barrier character;
wherein the half-sections are processed in a vacuum thermoforming die, and the vacuum thermoformed half-sections are bonded together along peripheral portions thereof to form a peripheral seam; and
wherein the balloon comprises an inflation element adapted to permit the inflation of the balloon at said physiological locus with a fluid; and
inflating the balloon, yielding a balloon that is non-pillowed and generally spherical or flattened spherical in shape.

Abstract
A method of treating a patient comprises: introducing to a physiological locus of said patient a balloon formed from two vacuum thermoformed half-sections of a multilayer film a layer of sealing film and at least one layer of thermoplastic polymer film, wherein the vacuum thermoformed half-sections are bonded together; and the balloon includes an inflation element (such as a self-healing valve and/or an effervescent material) adapted to permit inflation of the balloon at the physiological locus with a fluid.

17. A method of therapeutic intervention for treatment of a patient in need of such treatment, said method comprising:
-
introducing to a physiological locus of said patient a balloon formed from two vacuum thermoformed half-sections of a multilayer film comprising;
(A) a layer of sealing film comprising any of polyvinylidene chloride and an ethyl vinyl alcohol polymer, having main top and bottom surfaces;
laminated between (B) a first layer and a second layer of a thermoplastic polymer film;
wherein the sealing film has a composition and thickness imparting gas barrier character to the multilayer film and wherein either of the first layer and second layer of thermoplastic polymer film alone lacks such gas barrier character;
wherein the half-sections are processed in a vacuum thermoforming die, and the vacuum thermoformed half-sections are bonded together along peripheral portions thereof to form a peripheral seam; and
wherein the balloon comprises an inflation element adapted to permit inflation of the balloon at said physiological locus with a fluid; andinflating the balloon, yielding a balloon that is non-pillowed and generally spherical or flattened spherical in shape. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
