Claim 7:
8. A system comprising:
a cylindrical 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 with a top surface that is substantially circular and planar, wherein the top surface surrounds a central bore, wherein the circular body includes an instrument interface at a proximal end of the circular body, the instrument interface being positioned at the proximal end along an outer circumference of the circular body; and
a plurality of spikes extending from a distal side of the circular body, wherein an exterior surface of at least one spike of the plurality of spikes is at the outer circumference of the circular body,

wherein the annular anchor is removably coupleable to the anchor interface of the delivery device via the instrument interface, wherein the instrument interface includes one of: a downward-facing chamfered lip positioned on a lower side of the circular body and extending inwardly from a proximal end that is proximate to the top surface of the circular body to a distal end positioned underneath the top surface, 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.
