A coupling system includes an applicator tool and an attachment ring mounted on the applicator tool. Clips are contained within the applicator tool and are deployed through the attachment ring in order to anchor the attachment ring to biological tissue. When deployed, tips of the clips follow a curved trajectory through an annular cuff of the attachment ring and through the underlying tissue. The tips loop back out of the tissue and to a location where they are later trapped or clamped by the attachment ring. While the tips are trapped or clamped, the applicator tool cinches the clips by pulling rear segments of the clips. Thereafter, the applicator tool disconnects from the attachment ring which remains anchored to the tissue and serves as a coupling for a cannula. The cannula can have movable lock members that secure it to the attachment ring.

Systems for tissue repair are described where an elongate tissue repair device may be introduced into a single incision to access the damaged tissue. A suture delivery assembly may be sized for insertion through a single incision and positioned into proximity with a damaged or ruptured tissue region. A first portion of the damaged tissue region may be positioned within or along a channel defined along the suture delivery assembly and one or more lengths of suture may be secured to the first portion via the device. A second portion of the damaged tissue region may be similarly positioned within or along the channel and one or more additional lengths of suture may be secured to the second portion via the device. The first and second portions may then be approximated and secured to one another via the sutures to facilitate healing of the damaged tissue region.
