1. An anchoring system comprising:

  • an implant comprising a hub and a plurality of struts extending circumferentially around the hub, wherein the implant comprises a proximal end and a distal end, wherein the hub is located proximally, wherein at least one strut of the plurality of struts extends from the hub to the distal end of the implant, wherein the implant comprises a wider proximal end than distal end; and

    a helical tissue anchor comprising a proximal end and a sharpened distal tip, the proximal end of the helical tissue anchor located proximal to the annular hub, the hub dimensioned to receive the helical tissue anchor therethrough, wherein a portion of the helical tissue anchor is configured to be passed through a distal end of the hub and toward the distal end of the implant to drive the sharpened distal tip of the helical tissue anchor into tissue;

    wherein the helical tissue anchor comprises a first engagement structure, the first engagement structure for releasable engagement of a torque shaft;

    wherein the torque shaft comprises a second engagement structure for engaging the helical tissue anchor;

    wherein the torque shaft is configured to rotate the helical tissue anchor relative to the hub and into tissue, wherein the helical tissue anchor is configured to secure the implant to tissue.
