Abstract

A suture locking device including an adapter for insertion into a body. The adapter has a proximal end, an open distal end and a lip within the distal end projecting towards an interior of the open distal end. The device further includes a knot tying element releasably attached to the distal end of the adapter. The knot tying element has a distal and a proximal end. The proximal end of the knot tying element has a recess thereon. The proximal end of the knot tying element is inserted within the open distal end of the adapter such that the lip and the recess mate with each other to form a releasable lock.

Claims

1. A suture locking device comprising:

a. an adapter for insertion into a body, said adapter having a proximal end, an open distal end and a lip within said distal end projecting towards an interior of said open distal end;

b. a knot tying element releasably attached to said distal end of said adapter, said knot tying element having a distal and a proximal end, said proximal end of said knot tying element having a recess thereon, said proximal end of said knot tying element being inserted within said open distal end of said adapter such that said lip and said recess mate with each other to form a releasable lock.

2. The suture locking device of claim 1 wherein said knot tying element further comprises a locking element having a bore with a suture running therethrough, said locking element having an outer surface with a plurality of indentations disposed thereon.

3. The suture locking device of claim 1 wherein said distal end of said adapter has a first hole on a first side of said adapter and a second hole on a second side of said adapter wherein suture goes through said two holes and wherein said holes have centers which are at different locations along a longitudinal axis of said adapter.

4. The suture locking device of claim 1 further comprising a catheter having a distal end attached to said proximal end of said adapter.

5. The suture locking device of claim 4 further comprising a drive cable extending along and within said catheter, drive cable having a distal end attached to said proximal end of said adapter.

6. The suture locking device of claim 1 wherein said adapter is coupled to an endoscope.

7. The suture locking device of claim 6 wherein said adapter is inserted into the working channel of an endoscope.

8. The suture locking device of claim 1 wherein said adapter is substantially cylindrical.

9. The suture locking device of claim 8 wherein said adapter has an outer diameter less than 2.8 mm.

10. The suture locking device of claim 1 wherein said knot tying element further comprises a locking element having a bore with a suture running therethrough, said locking element having an outer surface with a plurality of indentations disposed thereon and wherein said locking element comprises polyetheretherketone.

11. A suture locking device comprising:

a. an adapter for insertion into a body, said adapter having a proximal end, an open distal end and a lip within said distal end projecting towards an interior of said open distal end;

b. a knot tying element releasably attached to said distal end of said adapter, said knot tying element having a distal and a proximal end, said proximal end of said knot tying element having a recess thereon, said proximal end of said knot tying element being inserted within said open distal end of said adapter such that said lip and said recess mate with each other to form a releasable lock; and

c. a catheter having a distal end attached to said proximal end of said adapter, and a drive cable extending along and within said catheter, drive cable having a distal end attached to said proximal end of said adapter.

12. The suture locking device of claim 11 wherein said knot tying element further comprises a locking element having a bore with a suture running therethrough, said locking element having an outer surface with a plurality of indentations disposed thereon.

13. The suture locking device of claim 11 wherein said distal end of said adapter has a first hole on a first side of said adapter and a second hole on a second side of said adapter wherein suture goes through said two holes and wherein said holes have centers which are at different locations along a longitudinal axis of said adapter.

14. The suture locking device of claim 11 wherein said adapter is coupled to an endoscope.

15. The suture locking device of claim 11 wherein said adapter is substantially cylindrical.

16. The suture locking device of claim 11 wherein said knot tying element further comprises a locking element having a bore with a suture running therethrough, said locking element having an outer surface with a plurality of indentations disposed thereon and wherein said locking element comprises polyetheretherketone.
