A single delivery needle configuration accommodates multiple soft tissue fixation devices at once. The configuration eliminates the need to reload a fixation delivery device when multiple fixation devices are required. Further, this configuration can include different variations of fixation devices. In embodiments, these fixation devices are typically manufactured from standard braided polyester suture that is cut into segments with predetermined lengths. This design allows the braided suture segments to be preloaded with a suture threaded through the preloaded braided suture segments with a slip knot placed on the proximal end of a first braided suture segments (e.g., distal fixation device). The tailing suture from the slip knot passes through the second, third, fourth braided suture segments, or any required quantity of braided suture segments that have been preloaded into the delivery device. The suture passes completely through a delivery device.

A system for attaching a first tissue to a second tissue that includes an instrument and an implant.

This invention discloses an anchor and anchor system for repairing soft tissue. The anchor includes an anchor body, a suture, and a flexible portion. One end of the suture is connected to the flexible portion, while the other end is free outside the anchor body. The flexible portion is fixed to the distal end of the anchor body under tension by the suture and has a permeable structure. The anchor can be used as a suture-attached anchor: after the anchor is placed in the target object, the free end of the suture passes through the soft tissue and is knotted, fixing the soft tissue to the surface of the target object. The suture free outside the target object after knotting is the soft tissue suture. Alternatively, the anchor can be used as a knotless anchor: the soft tissue suture passes through the permeable structure, placing the anchor in the target object and fixing the soft tissue suture within it. The flexible portion replaces existing terminals. Due to its inherent characteristics, after the anchor is implanted into the bone, the flexible portion is further compressed within the bone marrow tract, occupying almost no space and avoiding increasing the depth of the bone marrow tract.
