Abstract

A mounting structure for installation at a corporeal port opening. The mounting structure includes mounting structure for installation at a corporeal port opening, such mounting structure including a blowmolded article comprising enlarged cylindrical sections interconnected by tube segments, adapted to engage the corporeal port opening at a tube segment intermediate the enlarged cylindrical sections and with the enlarged cylindrical sections being in abutting contact with internal and external corporeal surfaces surrounding said port opening. 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 enlarged sections 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.

Claims

1. A mounting structure for installation at a corporeal port opening, said mounting structure including a blowmolded article comprising enlarged cylindrical sections interconnected by tube segments, adapted to engage the corporeal port opening at a tube segment intermediate said enlarged cylindrical sections and with the enlarged cylindrical sections being in abutting contact with internal and external corporeal surfaces surrounding said port opening.

2. The mounting structure of claim 1, formed of a thermoplastic polymeric thin-film material.

3. The mounting structure of claim 2, wherein said thermoplastic polymeric thin-film material comprises a polymer selected from the group consisting of polyethylene, polytetrafluoroethylene, polypropylene, polyurethane, polyvinylchloride, polyamide, polyether amide elastomer, styrenic elastomer, styrene isoprene butadiene (SIB)/styrene ethylene butadiene (SEB), and copolymers of monomers of the foregoing.

4. The mounting structure of claim 2, wherein said thermoplastic polymeric thin-film material comprises a thermoplastic elastomer (TPE) material.

5. The mounting structure of claim 2, wherein said thermoplastic polymeric thin-film material comprises a laminate.

6. The mounting structure of claim 5, wherein said a laminate comprises a barrier film, tie layer, and exterior layer.

7. The mounting structure of claim 1, as coupled with an ostomy bag.

8. The mounting structure of claim 2, wherein said thermoplastic polymeric thin-film material has a thickness of less than 25 mils.

9. The mounting structure of claim 1, including between an adjacent pair of enlarged sections a coaxial tubing portion including ribs or luminal passages therebetween.

10. The mounting structure of claim 1, including an integral flange.

11. The mounting structure of claim 9, wherein said coaxial tubing portion includes ribs or luminal passages that are adapted to be inflated in use.

12. The mounting structure of claim 11, wherein said ribs or luminal passages are inflated with an inflation medium.

13. The mounting structure of claim 12, wherein said inflation medium comprises air or water.

14. The mounting structure of claim 1, comprising a single enlarged section, and a coaxial tubing portion, and a flange.

15. The mounting structure of claim 1, comprising two enlarged sections, with a coaxial tubing portion therebetween.

16. The mounting structure of claim 15, wherein said coaxial tubing portion is reinforced by ribs or lumens.

17. The mounting structure of claim 15, further comprising a flange.

18. The mounting structure of claim 1, formed by extrusion blow molding.

19. The mounting structure of claim 1, formed by tube blow molding.

20. The mounting structure of claim 1, wherein the tube segments comprise coaxial tubes.

21. The mounting structure of claim 20, wherein the coaxial tubes have longitudinally extending ribs or lumens therebetween.
