Abstract
A low profile inflation valve includes a first tube having a lumen and at least one region of decreased inner diameter, and a structure, which may be a tube, movably located inside the lumen. The region of decreased inner diameter of the first tube forms a seal with a portion of the structure. A method of making a low profile inflation valve using a first tube and second tube comprises the steps of creating an aperture in at least one side of the second tube; placing the second tube inside the first tube, the first tube being made of thermoplastic material; applying heat to a localized area of the first tube; and compressing the first tube to form a region of reduced internal diameter, the reduced diameter forming a seal with the outside diameter of the second tube.
