Abstract

An endoluminal sleeve device for internally lining a section of the GI tract, comprises a sleeve configured for deployment inside a duodenum, the sleeve having walls of a flexible material defining a sleeve lumen, a proximal end defining a proximal lumen opening, and a distal end defining a distal lumen opening, an anchoring component having a slender transport configuration and a bulky deployed configuration, wherein the anchoring component is locatable at a distance from the proximal sleeve end and connected thereto by an elongated tether.

First claim

The invention claimed is:

1. An endoluminal sleeve device for internally lining a section of the GI tract, comprising:
a sleeve configured for deployment inside a duodenum, the sleeve having walls of a flexible material defining a sleeve lumen, a proximal end defining a proximal lumen opening, and a distal end defining a distal lumen opening; and
a ring attached to the proximal end of the sleeve, sized to remain within the stomach and having a circumferential outer surface;
wherein the circumferential outer surface of the ring is oriented perpendicular to the orientation of the proximal lumen opening of the sleeve.

2. The endoluminal sleeve device of claim 1 , wherein the proximal end of the sleeve is connected to the ring with a tether.

3. The endoluminal sleeve device of claim 2 , further comprising at least one elastic spread ring supported by the proximal sleeve end in a deformed wavy shape with undulations in a sleeve longitudinal direction, wherein the spread ring elastically biases the proximal sleeve end in a radially spread configuration while preserving a continuously convex outer contour.

4. The endoluminal sleeve device of claim 1 , wherein a proximal edge of the proximal sleeve end forms a funneled shaped sealing lip.

5. The endoluminal sleeve device of claim 1 , further comprising an elastic spring interposed between the ring and the proximal sleeve end.

6. The endoluminal sleeve device according to claim 5 , wherein said spring is formed by an elastic section.

7. The endoluminal sleeve device according to claim 5 , in which the spring comprises an elastic coil connected to the proximal sleeve end and tapered in a proximal direction towards the ring.

8. The endoluminal sleeve device of claim 2 , wherein a length of the tether between the ring and the proximal sleeve end is adjustable.

9. An endoluminal sleeve device for internally lining a section of the GI tract, comprising:
a sleeve configured for deployment inside a duodenum, the sleeve comprising a proximal end and a distal end: and
a ring attached to the proximal end of the sleeve, the sleeve extending radially outward from the ring.

10. The device of claim 9 , wherein the ring is substantially planar, and the sleeve extends radially outward from the ring and substantially in the same plane as the ring.

11. The device of claim 10 , wherein the ring comprises a slender transport configuration and a bulky deployed configuration.

12. The device of claim 11 , further comprising at least one elastic spread ring biasing the proximal end of the sleeve in a radially spread configuration.

13. The device of claim 12 , wherein the elastic spread ring comprises a spring with longitudinal undulations supported by the proximal end of the sleeve.

14. Endoluminal sleeve device anchoring system, comprising an endoluminal sleeve device according to claim 1 and an applier with a flexible shaft and an applier head arranged at a distal end of the flexible shaft, the applier head comprising:
a proximal coupler mount adapted to carry the ring,
a distal coupler mount operable to translate with respect to the proximal coupler mount and adapted to carry a ring-shaped proximal mounting structure of sleeve,
at least one pushing tube adapted to receive a tether and operable to translate with respect to both the proximal and distal coupling mounts through tether holes formed in the ring and towards a coupling seat formed in the sleeve mounting structure,
the tether being provided with a distal coupling tip adapted to connect with the coupling seats in the sleeve mounting structure.
