Abstract

Meniscal repair devices, systems, and methods are provided.

First claim

What is claimed is:

1. A surgical method, comprising:
advancing a cannula through tissue of a patient such that a proximal portion of the cannula is located outside of the patient and a distal portion of the cannula is located within the patient, the cannula including concentric inner and outer tubes that have distal ends fixed together;
with the distal portion of the cannula located within the patient, causing the distal portion to bend at an angle relative to a target tissue within the patient by moving the outer tube relative to the inner tube, wherein causing the distal portion to bend at the angle includes rotating an actuator that has threads thereon that are threadably engaged with threads on the outer tube, thereby causing longitudinal translation of the outer tube relative to the inner tube; and
after causing the distal portion to bend, advancing a surgical device through the cannula;
wherein the inner and outer tubes each extend distally from a handle of the cannula; and
with the outer tube longitudinally translatinu relative to the inner tube the outer tube is also longitudinally translatint relative to the handle and the inner tube is held in a fixed osition relative to the handle by a proximal coupling element fixed to the inner tube and seated in a depression formed in an interior of the handle.

2. The method of claim 1 , wherein the cannula is advanced through the tissue with the distal portion at a zero angle, and the angle to which the cannula is bent is a non-zero angle.

3. The method of claim 1 , wherein the cannula is bent from one non-zero angle to another non-zero angle.

4. The method of claim 1 , wherein the cannula is bent from a non-zero angle to a zero angle.

5. The method of claim 1 , wherein the surgical device includes a needle coupled to at least one pledget and at least one suture attached to the at least one pledget, the needle being configured to guide the at least one pledget and the at least one suture through a tissue.

6. The method of claim 1 , wherein the target tissue is a meniscus.

7. The method of claim 1 , wherein the tissue is at one of a knee, a hip, and a shoulder of the patient.

8. A surgical method, comprising:
advancing a cannula through tissue of a patient such that a proximal portion of the cannula is located outside of the patient and a distal portion of the cannula is located within the patient; and
advancing a surgical device through the cannula;
wherein the cannula includes a locking mechanism configured to lock the cannula in position relative to the surgical device advanced therethrough, and the cannula is automatically locked in position relative to the surgical device advanced therethrough;
the cannula also includes a second locking mechanism configured to lock the cannula in position relative to the tissue through which the cannula has been advanced; and
the method further comprises actuating an actuator to cause the cannula to be locked in position relative to the tissue.

9. A surgical method, comprising:
advancing a cannula through tissue of a patient such that a proximal portion of the cannula is located outside of the patient and a distal portion of the cannula is located within the patient, wherein the cannula includes concentric inner and outer tubes that have distal ends fixed together, the outer tube being configured to longitudinally translate, along a longitudinal axis of the outer tube, relative to the inner tube and thereby cause a distal portion of the cannula to articulate;
advancing a surgical device through the cannula; and
rotating an actuator that is threadably engaged with the outer tube, thereby causing longitudinal translation of the outer tube relative to the inner tube;
wherein the cannula includes at least one of a first locking mechanism configured to lock the cannula in position relative to the tissue through which the cannula has been advanced, and a second locking mechanism configured to lock the cannula in position relative to the surgical device advanced therethrough; and
wherein the rotation of the actuator also causes rotation of the outer tube relative to the inner tube.

10. The method of claim 8 , wherein the surgical device includes a needle coupled to at least one pledget and at least one suture attached to the at least one pledget, the needle being configured to guide the at least one pledget and the at least one suture through a tissue.

11. The method of claim 1 , wherein the cannula includes at least one of a first locking mechanism configured to lock the cannula in position relative to the tissue through which the cannula has been advanced, and a second locking mechanism configured to lock the cannula in position relative to the surgical device advanced therethrough.

12. The method of claim 9 , wherein the surgical device includes a needle coupled to at least one pledget and at least one suture attached to the at least one pledget, the needle being configured to guide the at least one pledget and the at least one suture through a tissue.

13. The method of claim 9 , wherein the cannula includes the second locking mechanism, and the cannula is automatically locked in position relative to the surgical device advanced therethrough.

14. The method of claim 9 , wherein the cannula includes the second locking mechanism, and the method further comprises actuating an actuator to cause the cannula to be locked in position relative to the surgical device advanced therethrough.

15. The method of claim 9 , wherein the cannula includes the first locking mechanism.

16. The method of claim 8 , wherein the cannula includes concentric inner and outer tubes that have distal ends fixed together, the outer tube being configured to longitudinally translate, along a longitudinal axis of the outer tube, relative to the inner tube and thereby cause a distal portion of the cannula to articulate; and
the method further comprises rotating an actuator that is threadably engaged with the outer tube, thereby causing longitudinal translation of the outer tube relative to the inner tube.
