Abstract

Endoscopic devices and methods used for fastening multiple tissue layers, such as, for example, an endoscopic fundoplication procedure, are disclosed. The device may include, for example, an elongated tubular member having a proximal end for extending outside of the body and a distal end for positioning proximate the multiple tissue layers, a grasper configured for positioning proximate the distal end of the tubular member and for grasping at least one of the multiple tissue layers, a device coupled to the distal end of the tubular member for folding the multiple tissue layers together, a tissue fastener configured to be inserted into the tissue layers to hold the tissue layers together, and a fastener head for inserting the tissue fastener into the tissue layers.

First claim

What is claimed is:

1. A system for fastening tissue, the system comprising:
a tubular member having a proximal end and a distal end, wherein the distal end is coupled to a first arm configured to pivot with respect to the tubular member to receive tissue;
a grasper configured for positioning proximate the distal end of the tubular member for grasping tissue; and
a fastener configured for insertion into the tissue, the fastener having a connecting member, a proximal fastening member, and a distal fastening member, wherein the connecting member connects the proximal fastening member to the distal fastening member, and wherein the fastener is adjustable between at least two implantation configurations, the at least two implantation configurations including: a) the connecting member having a first length between the proximal and distal members, and b) the connecting member having a second length between the proximal and distal members, wherein the second length is different than the first length,
wherein the tissue fastener is configured for delivery to the tissue through a lumen of the tubular member.

2. The system of claim 1 , wherein the distal end of the tubular member includes a second arm, and wherein tissue is received between the first arm and the second arm.

3. The system of claim 1 , wherein one of the proximal or distal fastening members is attached to a portion of the connecting member, and the other of the proximal or distal fastening members is movably coupled to the connecting member proximate the portion of the connecting member.

4. The system of claim 3 , wherein the fastener includes at least one element configured to prevent movement of the other of the proximal fastening member or the distal fastening member along the connecting member.

5. The system of claim 4 , wherein the at least one element includes a knot adjacent to the proximal fastening member or the distal fastening member.

6. The system of claim 4 , wherein the at least one element is configured to prevent movement of the proximal fastening member or the distal fastening member in only one direction.

7. The system of claim 1 , wherein the grasper is translatable relative to the distal end of the tubular member.

8. The system of claim 1 , wherein the grasper includes jaws.

9. The system of claim 1 , further comprising a needle, wherein at least a portion of the fastener is coupled to the needle.

10. A system for fastening tissue, the system comprising:
a tubular member having a proximal end and a distal end, wherein the distal end includes a first arm and a second arm, the first arm configured to pivot with respect to the second arm to receive tissue therebetween, wherein, when the first arm is in an open position relative to the second arm, a proximal-most end of the first arm is rotatably coupled to a distal end of the second arm;
a grasper configured for translation relative to the distal end of the tubular member for grasping tissue; and
a fastener configured for insertion into the tissue, the fastener having a connecting member, a proximal fastening member, and a distal fastening member, wherein the connecting member connects the proximal fastening member to the distal fastening member, and wherein the fastener is adjustable between at least two implantation configurations, the at least two implantation configurations including: a) the connecting member having a first length between the proximal and distal members, and b) the connecting member having a second length between the proximal and distal members, wherein the second length is different than the first length.

11. The system of claim 10 , further comprising a needle, wherein the first arm or the second arm includes a slot for receiving the needle.

12. The system of claim 11 , wherein at least a portion of the fastener is disposed within the needle.

13. The system of claim 10 , wherein the fastener is adjustable by moving at least one of the proximal fastening member or the distal fastening member with respect to the other of the proximal fastening member or the distal fastening member.

14. The system of claim 13 , wherein the proximal fastening member has a same shape as a shape of the distal fastening member.

15. The system of claim 10 , wherein the fastener comprises an elastic material.
