Method and apparatus for meniscal repair
View Patent ↗An apparatus for suturing tissue includes first and second needles. A first structure associated with the first needle is adapted and configured to pass a leading portion of the suture from a near side of a tissue to a far side of the tissue. A second structure cooperates with the second needle to capture and secure the suture. Proximal movement of the apparatus after the suture is captured moves the suture from the far side of the tissue to the near side of the tissue.
1. A method for suturing tissue, comprising:
providing a suturing apparatus including:
a housing;
a first needle mounted to the housing;
a second needle mounted to the housing, the second needle including a slot extending through an outer surface of the second needle and positioned proximal to a distal end of the second needle;
a first structure associated with the first needle;
a second structure associated with the second needle;
providing a length of suture including a leading portion, a trailing portion, a pre-formed uncinched knot formed in the trailing portion of the suture;
actuating the first structure associated with the first needle such that the first structure is advanced to pass the leading portion of the suture to the slot of the second needle; and
actuating the second structure associated with the second needle such that when the second structure is advanced the second structure retains the leading portion of the suture within the slot and the first structure is withdrawn.
2. The method of claim 1 , wherein at least one of the first and second needles is movably mounted to the housing.
3. The method of claim 1 , wherein the first structure comprises a suture holder extendable out of the first needle.
4. The method of claim 1 , wherein the first structure comprises an ejector wire.
5. The method of claim 4 , further comprising: translating the ejector wire through the slot associated with the second needle to pass the leading portion of the suture through the slot of the second needle.
6. The method of claim of claim 1 , wherein the second structure comprises an obturator.
7. The method of claim 6 , further comprising: translating the obturator through the second needle to capture the leading portion of the suture within the slot of the second needle.
8. The method of claim 1 , further comprising: passing the leading portion of the suture from a near side of a tissue to a far side of the tissue.
9. The method of claim 1 , further comprising: retracting the leading portion of the suture from a far side of a tissue to a near side of the tissue.
10. The method of claim 1 , further comprising: cinching the knot to secure the suture to a tissue.
11. The method of claim 1 , wherein the second structure holds the leading portion of the suture against an inner wall of the second needle.
