In one embodiment, a continuous suture passer device may include a first jaw, a second jaw, a tissue penetrator which may penetrate through tissue positioned between the first and second jaws, and a suture shuttle which may be releasably secured to the tissue penetrator and adapted to carry a suture. Further, the device may include an actuator which may manipulate at least one of the first or second jaws and the tissue penetrator, and the second jaw may have a suture shuttle retainer seat on which the suture shuttle may be releasably secured. The tissue penetrator may be movable towards the second jaw such that the suture shuttle carried by the tissue penetrator may be transferred to the shuttle retainer seat on the second jaw. Additionally, the first and second jaws may be substantially parallel to one another at any position to which the at least one jaw is manipulated. Additionally, the tissue penetrator may travel along an arcuate path from a first position, recessed within the first jaw, to a second position where the tissue penetrator extends through the tissue to be positioned in communication with the second jaw. Further, the at least one jaw may be manipulated such that it travels along a path that is substantially the same arcuate path traveled by the tissue penetrator. A method for passing a suture through tissue includes manipulation to transfer a suture shuttle adapted to carry a suture between a tissue penetrator and a second jaw.

Suture passers for suturing tissue in a continuous manner by passing a suture attached to a suture shuttle through. A suture passer may include a first jaw, a second jaw, and a tissue penetrator that is retractable and extendable from the first jaw. The tissue penetrator may have a suture shuttle engagement region, and the second jaw may include a shuttle dock. The suture shuttle may be transferred between the first and second jaws as the tissue penetrator is extended from the first jaw and engages the second jaw.

Methods of repairing knee meniscus tears are described which use suture passer devices and suture shuttles. These methods may be used with continuous suture passing, so that the suture passer device may remain on or in the tissue while passing a suture shuttle, and therefore a suture, back and forth from one side of the tissue to the other. These methods may be used minimally invasively for repairing meniscus tissue while avoiding further damage to the meniscus.

Described herein are methods and devices for use in repair of a patient's anterior cruciate ligament (ACL). These methods (and devices for performing them) allow the repair, rather than merely replacement, of the ACL. For example, described herein are anchoring devices that may be inserted into a bone and may anchor a scaffolding/support (e.g., graft) material within the bone so that the torn or damaged end of the ACL may be secured to the scaffolding/support material within the femoral notch. These anchoring devices and method of using them are particularly well suited for use with the continuous suture passers described herein, since these suture passers may allow access to previously inaccessible regions of the knee (or other body regions).
