Systems, Devices, and Methods for Securing Tissue using a Suture Having One or More Protrusions

摘要

Systems, devices, and methods are provided for securing soft tissue to bone. One exemplary embodiment of a surgical repair construct includes an anchor, a filament having a snare formed on one end and a collapsible loop on another end, and a suture having a plurality of stationary protrusions formed therein. The suture is configured to be coupled to detached tissue and have its ends passed through an opening in the snare. The snare can be collapsed around the suture such that at least one of the suture protrusions is proximal of the collapsed snare. The anchor can be disposed in bone and the filament coupled thereto. Accordingly, collapsing the snare around the suture couples the tissue to bone, and applying tension to a tensioning limb of the filament can collapse the collapsible loop to incrementally tighten and secure the tissue to bone. Other exemplary systems, devices, and methods for use with soft tissue repair are also provided.

主权项

1. A surgical repair construct, comprising:
an anchor capable of being fixated in bone and having a filament engagement feature; a filament capable of being passed through soft tissue to be repaired and having a collapsible snare formed on one end thereof and a collapsible loop at a second end thereof and coupled to the filament engagement feature, the collapsible loop including a sliding knot with a tensioning limb extending therefrom and effective to collapse the collapsible loop independent of the snare; and a suture having a plurality of stationary protrusions formed thereon in a spaced-apart arrangement, the suture being capable of being passed through soft tissue to be repaired, wherein an opening of the snare is configured to receive the suture, the snare being slidable with respect to the suture and collapsible around the suture, and wherein the collapsible loop is capable of being tightened incrementally to secure the soft tissue to the bone.
