OSTOMY BAG MOUNTING STRUCTURE
First Claim
1. A mounting structure for installation at a corporeal port opening, said mounting structure including 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, and with a gas flow passage associated with the tubing, 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.

- 1. A mounting structure for installation at a corporeal port opening, said mounting structure including 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, and with a gas flow passage associated with the tubing, for selective inflation of the balloon.
- 11. A method of making a mounting structure for installation at a corporeal port, said method comprising vacuum thermoforming each of two sheets of thermoplastic material to form a balloon half-section on each of said two sheets, welding said two sheets to one another to form a tube communicating with a balloon constituted by said balloon half-sections, wherein the tube has distal and proximal portions extending from said balloon, and everting the tube to insert one of the distal and proximal portions through the other one of said portions so as to protrude therefrom, with the balloon circumscribing a reentrant portion of the inserted one of the distal and proximal portions, so that such portions are arranged as coaxial tube segments in relation to one another.
