Multi-layer film welded articulated balloon
DC CAFCFirst Claim
1. A medical balloon device, comprising a multiplicity of layers of thermoplastic film including layers sealed at peripheral edges thereof to form an inflatable interior volume enclosed by the sealed edges, and layers sealed at one or more locations in the interior volume to enable the device to articulate to a predetermined shape upon inflation of the interior volume with an inflation fluid, to accommodate a predetermined medical application, wherein the inflatable interior volume is adapted to receive an inflation fluid.

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.
