1. A suture securing apparatus comprising:
- an apparatus body having an upper surface, a lower surface, a first internal surface, a second internal surface, an outer surface, and at least one aperture,the aperture having a longitudinal axis extending from the upper surface to the lower surface, a latitudinal axis extending from the first internal surface to the second internal surface, and defining an aperture surface, wherein a first longitudinal direction and a second longitudinal direction thereof each extends along the longitudinal axis in opposite directions, and a first latitudinal direction and a second latitudinal direction thereof each extends along latitudinal axis in opposite directions, the aperture including an integral locking means for engaging, and disengaging from, a suture threaded therethrough,the locking means formed so as to facilitate the movement of a suture in the first longitudinal direction and the first latitudinal direction along the aperture and to oppose the movement of the suture in the second longitudinal direction along the aperture until pressure is applied to the suture in the second latitudinal direction, thereby disengaging the locking means and permitting the movement of the suture in the second longitudinal direction along the aperture.

13. A suture securing apparatus comprising:
-
(a) an apparatus body having a upper surface, a lower surface, an outer surface, and at least one aperture, the aperture having a longitudinal axis extending from the upper surface to the lower surface and defining an aperture surface, wherein a first longitudinal direction and a second longitudinal direction thereof each extends along the longitudinal axis in opposite directions, the aperture consisting of an upper portion, a middle portion, and a lower portion, the upper portion bounded by the upper surface of the apparatus body and the middle portion, the middle portion bounded by the upper portion and the lower portion, and the lower portion bounded by the middle portion and the lower surface of the apparatus body, wherein the middle portion has a first surface and second surface opposing each other and is wider than either of the upper portion and the lower portion and forms a cavity therein; and (b) a movable cam member disposed in the middle portion of the aperture, the cam member having an engagement end and a rotation end, the rotation end being wider than the width of the upper portion of the aperture thereof and the width of the lower portion of the aperture thereof and disposed near the second surface, and the engagement end disposed near the first surface; wherein the cam member moves to an unengaged position to facilitate the movement of a suture threaded through the aperture in the first longitudinal direction along the aperture and moves to an engaged position to engage the suture threaded through the aperture in the second longitudinal direction by compressing the suture between the engagement end of the cam member and the first surface of the middle aperture to oppose the movement of the suture in the second longitudinal direction along the aperture. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 26, 28, 29, 30, 31)

32. A suture securing apparatus comprising:
-
an apparatus body having a upper surface, a lower surface, an outer surface, a first aperture, and a second aperture, the first longitudinal direction of each aperture each being directed to the upper surface of the apparatus body, wherein each ridge formed on the first aperture surface and second aperture surface is so formed as to facilitate the movement of a suture in the first longitudinal direction and oppose the movement of the suture in the second longitudinal direction, each ridge is formed at an angle of about 45°
to the longitudinal axis of the respective aperture, and the portion of each ridge extending farthest from the aperture surface is rounded, andwherein the first and second apertures are mirror images of each other, as defined by a mirror plane equidistant from them.

33. A suture securing apparatus comprising:
-
an apparatus body having a upper surface, a lower surface, an outer surface, and the apparatus body including a first aperture with a first movable cam member therein and a second aperture with a second movable cam member therein, the first longitudinal direction of each aperture each being directed to the upper surface of the apparatus body, wherein the first movable cam member and second movable cam member each moves to an unengaged position to facilitate the movement of a suture threaded through the respective aperture in the first longitudinal direction along the aperture and moves to an engaged position to engage the suture threaded through the respective aperture in the second longitudinal direction by compressing the suture between the engagement end of the respective movable cam member and the first surface of the middle aperture thereof to oppose the movement of the suture in a second longitudinal direction along the respective aperture; and wherein the first and second apertures and first and second cam members are mirror images of each other, as defined by a mirror plane equidistant from them.
