Abstract

The invention relates to a medical apparatus including a device used in the treatment of weight loss, obesity and potentially other associated health problems, e.g., type II diabetes. The device is used to impede absorption of nutrients within the gastrointestinal tract, i.e., bypassing a portion of the gastrointestinal tract. The medical apparatus enables implantation of the device using minimally invasive techniques, such a transesophageal approach under visualization. The device may be implanted via a working channel of a medical scope, e.g., an endoscope or in combination with a medical scope.

Claims

1. A medical apparatus, comprising:

a sleeve;

non-circular anchoring component attached to at least a portion of said sleeve; and

a delivery tube having a lumen and said sleeve being substantially fully inverted and contained within the lumen of said delivery tube.

2. The medical apparatus of claim 1, wherein the delivery tube is configured to fit inside a working channel of an endoscope.

3. The medical apparatus of claim 2, wherein said working channel of said endoscope has a diameter of about 10 mm or less.

4. The medical apparatus of claim 1, further comprising a connector removably coupled to a proximal end of said delivery tube.

5. The medical apparatus of claim 1, further comprising a sheath removably coupled to a distal end of said delivery tube.

6. The medical apparatus of claim 1, wherein said anchoring component comprises a nickel titanium alloy.

7. The medical apparatus of claim 1, wherein said anchoring component comprises a biodigestible material.

8. The medical apparatus of claim 1, wherein said anchoring component comprises a radiopaque material.

9. The medical apparatus of claim 1, wherein said anchoring component has a tapered helical pattern.

10. The medical apparatus of claim 1, wherein said anchoring component includes at least one of a passive anchoring element and an active anchoring element.

11. The medical apparatus of claim 1, wherein said anchoring component is at least partially covered with a thermoplastic material.

12. The medical apparatus of claim 1, wherein the anchoring component is arranged on an outer surface of said sleeve.

13. The medical apparatus of claim 1, wherein the anchoring component comprises a bioabsorbable material.

14. The medical apparatus of claim 1, wherein said delivery tube comprises a thermoplastic material.

15. The medical apparatus of claim 13, wherein said thermoplastic material comprises nylon.

16. The medical apparatus of claim 13, wherein said nylon comprises polyether block amide.

17. The medical apparatus of claim 1, wherein said sleeve comprises a fluoropolymer.

18. The medical apparatus of claim 17, wherein said fluoropolymer comprises polytetrafluoroethylene.

19. The medical apparatus of claim 18, wherein said polytetrafluoroethylene comprises expanded polytetrafluoroethylene.

20. The medical apparatus of claim 1, wherein said sleeve comprises fluorinated ethylene propylene.

21. The medical apparatus of claim 1, wherein said sleeve has a tapered configuration.

22. The medical apparatus of claim 1, further comprising a balloon capable of expanding said anchor.

23. The medical apparatus of claim 1, wherein said sleeve comprises markings indicating length graduations.

24. The medical apparatus of claim 1, wherein said sleeve comprises a radiopaque material.

25. The medical apparatus of claim 1, wherein said sleeve is in a compacted configuration within the lumen of said delivery tube.
