MULTI-LAYER FILM WELDED ARTICULATED BALLOON
First Claim
1. A method for the fabrication of an articulated medical balloon device comprising the steps of(a) providing at least two film layers having opposed edges;
- (b) sealing said opposed edges to form a compartment adapted to receive fluid to expand said film layers relative to each other;
(c) providing an opening in said fluid compartment that is adapted to receive a lumen; and
(d) forming a subcompartment between the sealed edges of said compartment of a predetermined shape and dimension by sealing at least one of said layers to another, intermediate said opposed edges.

Abstract
A method of fabrication of a medical balloon, and a balloon device useful for various medical balloon procedures, such as gastrointestinal, vascular, reproductive system, urinary system and pulmonary applications. At least two layers of a thermoplastic film are sealed at their peripheral edges and heat sealed at one or more locations inside an area enclosed by the sealed edges at predetermined locations, in one implementation of the balloon device. Such configuration enables the balloon to articulate to a desired shape upon inflation, with the desired shape being selected to accommodate a specific medical application.
