Ostomy bag mounting structure
First Claim
1. 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.

Abstract
A mounting structure for installation at a corporeal port opening. The mounting structure includes a reentrant tube on an exterior surface of which is disposed at least one balloon, with a proximal everted portion of the tubing extending from the distal portion of the tubing, with a gas flow passage associated with the tubing, for selective inflation of the balloon. A vacuum thermoforming process for making such mounting structure is described. The mounting structure is useful employed for anchoring of a therapeutic device such as an ostomy bag at a corresponding port of the body, with the balloon(s) of the device providing effective anchoring of the mounting structure and permitting the mounting structure to be comfortably worn by a patient during therapeutic intervention.
