Abstract

An anchor assembly can include at least one anchor member, such as a pair of anchor members that are configured to be implanted in a target anatomical location in a first configuration, and can subsequently be actuated to an expanded configuration that secures the anchor members in the target anatomy. The anchor assembly can further include a connector member that attaches the pair of anchor members together across a gap so as to approximate the anatomical defect.

First claim

We claim:

1 . An anchor assembly configured to be anchored to an anatomical location, the anchor assembly comprising:
an anchor including an anchor body that defines an expandable portion, the expandable portion defining a direction of elongation, the anchor body defining a plurality of openings that extend through the expandable portion and are spaced substantially along the direction of elongation; and the anchor further including an actuation member that extends through at least two of the openings, the actuation member configured to receive an actuation force and, in response to the actuation force, actuate the expandable portion from a first configuration, wherein the expandable portion defines a first maximum thickness along a second direction that is angularly offset from the direction of elongation, to an expanded configuration, wherein the expandable portion defines a second maximum thickness along the second direction that is greater than the first maximum thickness.
