Claim 6:
7. A system comprising:
an elongate delivery device comprising a distal end, a proximal end, and a lumen extending from the distal end to the proximal end, the distal end including an anchor interface;
an annular anchor comprising:
a circular body surrounding a central bore and including an instrument interface along an edge of an outer circumference, wherein the instrument interface includes a downward-facing chamfered lip positioned on a lower side of the circular body along at least a portion of the outer circumference, wherein the downward-facing chamfered lip is positioned along at least a portion of the edge of the outer circumference and extends inwardly from a proximal end that is proximate to a top surface of the circular body to a distal end positioned underneath a top surface; and
a plurality of spikes extending from a distal side of the circular body,
wherein the downward-facing chamfered lip is a sloped transition surface between the edge of the outer circumference and an edge of a substantially planar surface through which the central bore passes,
wherein the annular anchor is removably coupleable to the anchor interface of the delivery device via the instrument interface, and wherein the anchor interface includes a plurality of biasable arms and at least one side portion positioned between adjacent biasable arms of the plurality of biasable arms, each biasable arm including a distal end adapted to engage the downward-facing chamfered lip; and

an implant deliverable through the delivery device and implantable through the annular anchor.
