Abstract

Claims (12)

1. A system for treatment of body tissue, comprising:

an anchor assembly, the anchor assembly including a first component attached to a connector and a second anchor component; and

a delivery device, the delivery device including a handle, an elongate portion extending in a proximal to distal direction from the handle, the elongate portion including a leading end, a needle tube, and a scope lumen terminating within the leading end of the elongate portion, a needle assembly extending through the needle tube and configured to be advanced from the leading end, and the connector extending through the needle assembly;

wherein a terminal end portion of the needle assembly has a start position distal to and within view of the scope lumen and within the leading end of the elongate portion and the needle tube has a distal end that is distal to and within view of the scope lumen.

2. The system of claim 1 , wherein the leading end is configured with a guide to constrain the needle assembly to exit the leading end in a generally perpendicular direction with respect to the elongate portion.

3. The system of claim 1 , wherein the needle assembly has a start position in a path of the second anchor component.

4. The system of claim 1 , wherein the needle has a beveled tip on another side of the needle assembly from that of an inside radius as it is ejected from the delivery device.

5. The system of claim 1 , wherein the scope lumen is laterally offset from the needle tube.

6. The system of claim 5 , wherein one or more of the scope lumen and needle assembly are configured to be laterally translated.

7. The system of claim 1 , further comprising an endoscope configured to be translated axially within the scope lumen.

8. The system of claim 1 , further comprising a cover, wherein the cover is positioned between the needle tube and scope lumen.

9. The system of claim 1 , wherein a viewing space is provided distal to scope lumen within the elongate portion.
