Patent ID: 8167859

Claim:
A mounting structure formed of a thermoplastic polymeric thin-film material for installation at a corporeal port opening, said mounting structure including a thermoplastic polymeric thin-film balloon and tube assembly comprising at least one balloon communicating with distal and proximal tube segments, said balloon and tube assembly including twin sheets of said thermoplastic polymeric thin-film material that are leak-tightly welded at edge seams to one another and include in each sheet at least one balloon half-section, wherein each balloon half-section communicates with distal and proximal tube segment half-sections, wherein said balloon and tube assembly comprises at least one balloon through which one of the distal and proximal tube segments communicating with the balloon extends, through an interior volume of the balloon and through the other of said distal and proximal tube segments, so that the balloon is internally supported only by the one of the distal and proximal tube segments extending through its interior volume in said assembly, and wherein ribs on said tube segments are oriented longitudinally thereon, said mounting structure further including a gas flow passage, for selective inflation of the balloon.
