Abstract

A non-surgical gastric bander device and process is described. The non-surgical gastric bander device includes a staple device, an elongated articulated shaft, an operations handle and a cable connecting the operations handle to the staple device. The staple device includes a housing having an interior housing channel for receiving a slidable tube. The slidable tube includes at least one suction port, a constriction band surrounding the exterior surface of the slidable tube and a plurality of staples removably positioned adjacent the exterior surface of the slidable tube and held in place by the constriction band. The gastric bander device further includes an elongated, articulated shaft connecting the staple device to an operations handle.

2. The staple device of claim 1 wherein the first end of the housing comprises a staple ring.

3. The staple device of claim 2 wherein the staple ring comprises outwardly extending staple grooves.

4. The staple device of claim 1 wherein the slidable tube includes a plurality of staple grooves, each staple groove adapted to removably receive a staple.

5. The staple device of claim 4 wherein each staple groove includes a plurality of suction ports.

6. The staple device of claim 1 wherein each staple of the plurality of staples has an elongated shaft having a first and second end, wherein each end extends from the shaft at an approximately 90 degree angle, wherein further the shaft has a thinner area at a point on the shaft to facilitate flexure and bending of the staple.

7. The staple device of claim 1 wherein the guide edge of the anvil comprises a beveled edge between the first upper surface and the second lower surface of the anvil, wherein the beveled edge includes outwardly extending staple grooves, wherein the anvil further includes a notch.

8. The staple device of claim 1 further comprising a cable rotatably connected to the second lower surface of the anvil, wherein the cable further includes a compression spring for rotating the anvil.

9. The staple device of claim 8 further comprising means to extend and constrict the cable.

10. The staple device of claim 9 wherein the means to extend and constrict the cable is an operations handle comprising a mechanism for extending and constricting the cable.

11. An articulated shaft having a proximal and a distal end comprising a plurality of adjacent links, wherein each link is pivotally attached to an adjacent link in a manner to allow limited pivoting movement of the shaft in both an X and a Y axis,

a. wherein each link comprises an outer surface, an inner surface forming an interior passageway, an upper first surface comprising an arched protrusion including a pair of outwardly extending lips, and a lower second surface comprising an arched notch comprising a pair of inwardly depending edges wherein the pair of outwardly extending lips of the upper first surface are formed to receive the pair of inwardly depending edges of the next adjacent link in a snap fit fashion to connect each adjacent link in a manner allowing limited pivoting movement of the connected adjacent links in both an X and a Y axis, and

b. wherein the articulated shaft further comprises a cable having a proximal and a distal end, wherein the proximal end of the cable is connected to a stopper mechanism at the proximal end of the articulated shaft and the distal end is connected to a means for extending or constricting the cable, wherein the constriction of the cable prevents pivotal movement of adjacent links with respect to each other and the extension of the cable allows pivotal movement of adjacent links.

12. The articulated shaft of claim 11 wherein the upper first surface is beveled to assist in the pivotal movement of each adjacent link.

13. The articulated shaft of claim 11 wherein the lower second surface is beveled to assist in the pivotal movement of each adjacent link.

14. The articulated shaft of claim 11 wherein the upper first surface and the lower second surface are both beveled to assist in the pivotal movement of each adjacent link.

15. The articulated shaft of claim 11 wherein the upper first surface is defined by a roughened or knurled surface to assist in prevention of pivotal movement of adjacent links when the cable is constricted.

16. The articulated shaft of claim 11 wherein the lower second surface is defined by a roughened or knurled surface to assist in prevention of pivotal movement of adjacent links when the cable is constricted.

17. The articulated shaft of claim 11 wherein the upper first surface and the lower second surface are defined by a roughened or knurled surface to assist in prevention of pivotal movement of adjacent links when the cable is constricted.

18. A non-surgical gastric bander comprising:

a. a staple device including

i. a housing having a first end and a second end and an interior housing channel, wherein the first end of the housing comprises a staple ring comprising outwardly extending staple grooves;

ii. a slidable tube for slidable reception within the interior housing channel and having a first end, a second end, an exterior surface and an interior surface forming an open tube channel within the slidable tube, wherein the slidable tube includes a plurality of staple grooves, each staple groove adapted to removably receive a staple;

iii. at least one suction port comprising an opening from the exterior surface of the slidable tube to the tube channel;

iv. a constriction band surrounding the exterior surface of the slidable tube;

v. a plurality of staples removably positioned adjacent the exterior surface of the slidable tube and held in place by the constriction band; and

vi. an anvil removably positioned on the first end of the slidable tube, the anvil including a first upper surface and a second lower surface, wherein the second lower surface has a shape substantially similar to the first end of the slidable tube, the anvil further including a guide edge for the plurality of staples;

b. an elongated, articulated shaft having a proximal end and a distal end, wherein the proximal end is connected to the first end of the housing, the articulated shaft being surrounded by an air impervious membrane;
