1. An external suture securement apparatus, comprising:
- a base paddle having a wing portion and defining a slot extending at least partially through the base paddle, wherein the base paddle defines a suture aperture extending therethrough and being adapted to receive a suture, wherein the suture aperture is in communication with and extends transversely through the slot; and
a rotating paddle having a wing portion and an extension arm rotatably received in the slot along a connection axis, wherein the extension arm defines a suture aperture extending therethrough and being adapted to receive a suture, wherein the extension arm is configured to rotate in the slot to frictionally crimp a suture extending through the suture apertures, wherein the extension arm includes a detent mechanism configured to maintain positioning of the extension arm in the slot and prevent disengagement of the rotating paddle from the base paddle;
wherein at least one of the base paddle and the rotating paddle includes a locking mechanism configured to lock the rotational position of the rotating paddle with respect to the base paddle;
wherein, in an uncrimped configuration, the suture apertures in the base paddle and the rotating paddle are in axial alignment such that the suture is freely moveable within the apertures, and wherein the wing portions of the base paddle and the rotating paddle extend from the connection axis positioned adjacent each other in a substantially planar arrangement,wherein, in a crimped configuration, the suture apertures in the base paddle and the rotating paddle are not in axial alignment to frictionally crimp a suture within the slot such that the suture is substantially prevented from moving with the apertures, and wherein the wing portions of the base paddle and the rotating paddle are positioned in a non-planar arrangement and configured to be locked in position via the locking mechanism.

Abstract
Described are devices, methods and systems for securing sutures external to the body. In certain aspects, a suture securement device includes a base paddle defining a slot and a suture aperture in communication with the slot, and a rotating paddle having an extension arm with a suture aperture. In such embodiments, the extension arm can rotate within the slot to frictionally crimp a suture, such that the suture is substantially prevented from moving with the apertures.
