Anchor delivery System
View Patent ↗A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes a delivery device configured to deploy and implant anchor devices for such purposes.
1. A system for treatment of body tissue, comprising:
a delivery device comprising an elongate distal end and a proximal handle;
a needle assembly configured to deploy a needle through a window in the elongate distal end, wherein the needle delivers a first anchor assembly and a connector;
a cutter assembly configured to move along the long axis of the elongate distal end to cut the connector, the cutter assembly operatively connected to a cutter block within the proximal handle; and
a pusher assembly configured to move along the long axis of the elongate distal end to push a second anchor assembly onto the connector, the pusher assembly operatively connected to a pusher block within the proximal handle;
wherein the cutter block and pusher block cooperate to push the second anchor assembly onto the connector prior to cutting the connector.
2. The system of claim 1 wherein the window is on a side of the elongate distal end.
3. The system of claim 1 further comprising a cover configured to exclude tissue from entering the window and permit deployment of the needle.
4. The system of claim 1 wherein the cutter assembly comprises a cutter window.
5. The system of claim 4 wherein the needle is deployed through the cutter window.
6. The system of claim 1 wherein the cutter assembly is configured to cut the connector when the cutter assembly is moved proximally.
7. The system of claim 1 wherein the cutter assembly is configured to cut the connector when the cutter assembly is moved distally.
8. The system of claim 1 wherein the cutter assembly comprises at least one guide to guide the connector into position to be cut.
9. The system of claim 1 , wherein the cutter assembly includes a structure for aligning the connector with the second anchor assembly.
10. The system of claim 1 wherein the cutter assembly comprises a spacing structure for providing spacing to cut the connector.
11. The system of claim 1 wherein the cutter assembly comprises an offset blade for providing spacing to cut the connector.
12. The system of claim 1 wherein the cutter assembly is configured to cut the connector while the connector is positioned within the window.
13. The system of claim 1 wherein the elongate distal end comprises at least one guide for aligning the second anchor assembly.
14. The system of claim 1 wherein the pusher assembly comprises at least one guide for aligning the second anchor assembly.
15. The system of claim 1 wherein the cutter assembly comprises at least one guide for aligning the second anchor assembly.
16. The system of claim 1 wherein the cutter block and the pusher block are connected by a spring.
17. The system of claim 1 wherein the cutter block is prevented from actuating the cutter assembly by a pawl operatively connected to the pusher block.
18. The system of claim 17 wherein the pawl is disengaged from preventing the actuation of the cutter assembly when the pusher block actuates the pusher assembly.
19. The system of claim 1 further comprising at least one window in the proximal handle wherein the window provides access to a manual override.
20. The system of claim 1 wherein the needle assembly, the cutter assembly, and the pusher assembly are configure to be lockable by a locking mechanism within the proximal handle.
