Abstract

A tissue connecting device is provided. The device comprise an elongate delivery device having a lumen, a proximal end, and a distal end. The distal end is configured to engage tissue and advance said device into tissue. At least one anchor deliverable through a lumen of the elongate delivery device. The distal end of the device may be designed to engage tissue upon rotation of the device about its longitudinal axis.

Claims

1. A tissue connecting device, the device comprising:

an elongate delivery device having a lumen, a proximal end, and a distal end;

wherein said distal end is configured to engage tissue and advance said device into tissue;

at least one anchor deliverable through a lumen of said elongate delivery device.

2. The device of claim 1 wherein said delivery device pierces tissue through rotation of the delivery device about a longitudinal axis.

3. The device of claim 1 further an elongate member deliverable to the target site via a guide catheter, said elongate member assuming a first substantially linear configuration while engaged with said guide catheter and a second substantially circular configuration defining a first support ring and a second support ring when removed from the guide catheter.

4. The device of claim 2 wherein said elongate member is slidable delivered along at least one suture coupled to said anchor.

5. The device of claim 1 wherein a helical configuration is laser cut at the distal end of the delivery device.

6. The device of claim 1 wherein threads are formed on the distal end of the delivery device and adapted to engage tissue.

7. The device of claim 1 wherein said at least one anchor has threads and are adapted to engage tissue.

8. The device of claim 1 wherein said at least one anchor has a helical configuration.

9. The device of claim 1 wherein said at least one anchor has a suture coupled to a distal end of the anchor.

10. The device of claim 1 further comprising a plurality of anchors wherein each anchor is coupled together by a suture.

11. The device of claim 1 further comprising a plurality of anchors wherein each anchor is coupled together by a suture.

12. The device of claim 1 wherein said anchor has a shape selected from one of the following:

screw, a helix, a helix with variable radii, a bar, a hollow elongate portion or coiled shape.

13. The device of claim 1 wherein said anchor includes an eyelet for an anchor.

14. The device of claim 1 wherein said anchor includes means for attaching into tissue.

15. A system for tissue connection comprising:

an elongate delivery device having a lumen, a proximal end, and a distal end;

wherein said distal end is configured to engage tissue and advance said device into tissue through rotation of the delivery device about a longitudinal axis;

means for anchoring tissue deliverable through said delivery device;

an elongate member deliverable to the target site via a guide catheter, said elongate member assuming a first substantially linear configuration while engaged with said guide catheter and a second substantially circular configuration defining a first support ring and a second support ring when removed from the guide catheter.

16. A system for tissue connection comprising:

a plurality of tissue anchors coupled to a single suture, wherein said suture is slidably coupled to each anchor, wherein the anchors are configured so that tissue coupled to each of said anchors will be draw together when the suture is tightened.
