Abstract

An assembly that delivers tissue fasteners for deployment in tissue comprises a stylet that guides a fastener into tissue. The stylet has a proximal end. The assembly further includes a bolt attached to the proximal end of the stylet, a receiver that slidingly receives the bolt permitting linear movement of the bolt and stylet along a path. The assembly may further comprise a pusher that intersects the path of the stylet and pushes the fastener along the stylet towards and into the tissue.

Claims

1. An assembly comprising:

a stylet that guides a fastener into tissue, the stylet having a proximal end;

a bolt attached to the proximal end of the stylet;

a receiver that slidingly receives the bolt permitting linear movement of the bolt and stylet along a path into the tissue.

2. The assembly of claim 1 further comprising a pusher that intersects the path of the stylet and pushes the fastener along the stylet.

3. The assembly of claim 2, wherein the pusher is carried on the stylet distal to where the pusher intersects the path of the stylet.

4. The assembly of claim 2, wherein the bolt includes a lumen that slidingly receives the pusher.

5. The assembly of claim 2, wherein the pusher intersects the path at an intersection and wherein the assembly further includes a loading station that permits a fastener to be loaded onto the stylet, the loading station being distal to the intersection.

6. The assembly of claim 2, wherein the pusher is tubular and includes an opening permitting the pusher to be received on the stylet.

7. The assembly of claim 1, further comprising a loading station that permits a fastener to be loaded onto the stylet and having a given length dimension and a fastener loader, the fastener loader having a width dimension less than the given length dimension for loading a fastener onto the stylet within the loading station.

8. The assembly of claim 7, wherein the fastener loader is arranged to carry a plurality of the fasteners.

9. The assembly of claim 1, wherein the bolt includes a projecting handle and wherein the receiver includes a track that receives the handle and restricts movement of the bolt.

10. The assembly of claim 9, wherein the track includes at least one transverse slot that receive the bolt handle and locks the bolt in a predetermined longitudinal position.

12. The assembly of claim 10, wherein the first and second subassemblies are arranged side-by-side on the common housing.

11. An assembly comprising:

a first subassembly including a first stylet that guides a first fastener into tissue and having a proximal end, a first bolt attached to the proximal end of the first stylet, a first receiver that slidingly receives the first bolt permitting linear movement of the first bolt and stylet along a first path into the tissue; and

a second subassembly including a second stylet that guides a second fastener into the tissue and having a proximal end, a second bolt attached to the proximal end of the second stylet, a second receiver that slidingly receives the second bolt permitting linear movement of the second bolt and stylet along a second path into the tissue,

the first and second subassemblies being carried by a common housing.

13. The assembly of claim 11 wherein the first subassembly comprises a first pusher that intersects the first path of the first stylet and pushes the first fastener along the first stylet and wherein the second subassembly comprises a second pusher that intersects the second path of the second stylet and pushes the second fastener along the second path.

14. The assembly of claim 13, wherein the first and second pushers are carried on the first and second stylets distal to where the first and second pushers intersect the first and second paths of the first and second stylets, respectively.

15. The assembly of claim 13, wherein the first and second bolts include first and second lumens that slidingly receive the first and second pushers, respectively.

16. The assembly of claim 13, wherein the first and second pushers intersect the first and second paths at first and second intersections, respectively, and wherein the assembly further includes first and second loading stations that permit the first and second fasteners to be loaded onto the first and second stylets, the first and second loading stations being distal to the first and second intersections.

17. The assembly of claim 16, wherein each of the loading stations has a given length dimension and wherein the assembly further comprises a fastener loader, the fastener loader having a width dimension less than the given length dimension for loading a fastener onto the first and second stylets within the first and second loading stations

18. The assembly of claim 17, wherein the fastener loader is arranged to carry a plurality of the fasteners.

19. The assembly of claim 13, wherein the first and second pushers are tubular and wherein each of the first and second pushers includes an opening permitting the first pusher to be received on the first stylet and the second pusher to be received on the second stylet.

20. The assembly of claim 11, wherein the first and second bolts each includes a projecting handle and wherein the first and second receivers each includes a track that receives the handle and restricts movement of its respective bolt.

21. The assembly of claim 20, wherein each track includes at least one transverse slot that receive its respective bolt handle and locks its respective bolt in a predetermined longitudinal position.
