Abstract
Anchor towers useful in the alteration of a position of an item connected to an anchor are described. An anchor tower includes an inner sleeve and an outer sleeve disposed over and operably connected to the inner sleeve such that movement of the outer sleeve results in movement of the inner sleeve. A groove is disposed on the inner sleeve and an inwardly-extending projection is disposed on the outer sleeve. Relative movement between the inner and outer sleeves results in movement of the projection within the groove. This movement can produce desired movement of a portion of the inner sleeve, such as a distal arm, based on a structural configuration of the groove.
