Abstract
An anchor assembly having a helical anchor extending through an anchor bore defined in the anchor housing. In some embodiments, at least one helical turn of the helical anchor extends beyond a portion of the anchor bore. In some embodiments, at least one helical turn of the helical anchor extends beyond a side wall of the anchor housing. In some embodiments, the helical turns of the helical anchors of anchor assemblies mounted adjacent one another on an implantable device nest within one another when the implantable device is in an unexpanded configuration. In some embodiments, the distalmost helical turn of the helical anchor has an outer diameter greater than more proximal helical turns of the helical anchor. In some embodiments, the outer diameters of the at least some of the helical turns of the helical anchor taper from a distal end to a proximal end of the helical anchor.
