22. A connector delivery system, comprising:
-
a retractor;
a tube integral with a plurality of puller spikes of said connector, said tube coupled to said retractor for retraction thereby, said spikes defining at least one thickened areas on at least one spike; and
a base ring for preventing said at least one thickened areas from retracting, thereby causing said spikes to tear when said retractor retracts said tube a sufficient amount. - View Dependent Claims (23, 24)
