1. A tissue repair device comprising:
a handle having a proximal end, and a distal end;
a hub operatively coupled to the handle;
a needle assembly disposed at least partially within a channel extending through the hub and the handle;
a depth tube including a cannulation configured to receive at least a portion of the needle assembly therein; and
a limiter member comprising a housing disposed within the hub and a shaft extending from a distal end of the hub, the shaft configured to engage the cannulation of the depth tube, the limiter member defining a cannulation extending along a longitudinal axis for passage of an actuator into the needle assembly, the limiter member having a flexible portion positioned above the longitudinal axis and engageable by a user for allowing axial movement of the depth tube relative to the needle assembly;
wherein the housing of the limiter member comprises a flexure positioned below the longitudinal axis and configured to engage a recess in the hub to limit distal movement of the limiter member relative to the hub, the flexure coupled to an inner surface of the cannulation of the limiter member and extending proximally from the cannulation of the limiter member.
