Claim:
1. An anchor tower, comprising: an inner sleeve having a first outer surface, a first lateral surface that is different than the first outer surface, a first proximal end and a first distal end, an outer thread disposed on the first proximal end, and the first outer surface defining a groove on the first distal end having a proximal portion and a distal portion, the first outer surface defining a first lateral opening in communication with the groove and open to the first lateral surface, the first lateral opening being a flared opening in the proximal portion, the groove having a closed distal end in the distal portion, the groove comprising a tortuous path; an outer sleeve disposed over the inner sleeve and having an inner surface, a second proximal end and a second distal end, the second proximal end defining a chamber and the inner surface defining an inwardly-extending projection; an actuator disposed within the chamber and defining an inner thread mated with the outer thread, the actuator rotatable within the chamber about a lengthwise axis of said anchor tower; wherein the inner sleeve moves axially along the lengthwise axis in response to rotational movement of the actuator such that the inwardly-extending projection moves within the groove; and wherein the flared opening provides play in the interaction with the inwardly-extending projection as the inwardly-extending projection enters the groove.
