1. A suture retention means for use in approximating an object to an anatomical structure by at least one length of suture extending outwardly from said anatomical structure and through said object, said suture retention means comprising:
- a substantially frusto-conical body having a longitudinal axis, a top surface, a bottom surface, a side surface and a longitudinally-centered cavity extending into said top surface;
said top and bottom surfaces each (a) being substantially planar, (b) being oriented in spaced, parallel relation to one another, and (c) defining a substantially circular periphery centered about said longitudinal axis, said periphery of said bottom surface being smaller than said periphery of said top surface;
said side surface extending in a substantially frusto-conical monomer between said periphery of said top surface and said periphery of said bottom surface;
said longitudinally-centered cavity including a base surface, a sidewall surface and an open end; and
said body further defining at least one opening extending from said bottom surface to said base surface, each said opening being sized so as to allow at least one free end of at least one length of suture to be threaded therethrough from said bottom surface into said longitudinally-centered cavity, and so as to prevent a knot formed by said at least one free end of suture from passing therethrough.

Abstract
A suture retaining device in the form of a frusto-conical button having parallel upper and lower planar surfaces which are connected together by a conical surface. The button is provided with a recessed chamber for substantially completely accommodating one or more suture knots. At least one hole is formed in the button leading from the recessed chamber to the lower planar surface, and at least one hole is formed in said button leading from the recessed chamber to the conical surface.

5. A suture retention means for use in approximating an object to an anatomical structure by at least one length of suture extending outwardly from said anatomical structure and through said object, said suture retention means comprising:
-
a substantially frusto-conical body having a longitudinal axis, a top surface, a bottom surface, a side surface and a longitudinally-centered cavity extending into said top surface; said top and bottom surfaces each (a) being substantially planar, (b) being oriented in spaced, parallel relation to one another, and (c) defining a substantially circular periphery centered about said longitudinal axis, said periphery of said bottom surface being smaller than said periphery of said top surface; said side surface extending between said periphery of said top surface and said periphery of said bottom surface; said longitudinally-centered cavity including a base surface, a sidewall surface and an open end; and said body further defining at least one opening extending from said side surface to said sidewall surface, each said opening being sized so as to allow at least one free end of at least one length of suture to be threaded therethrough from said side surface into said longitudinally-centered cavity, and so as to prevent a knot formed by said at least one free end of suture from passing therethrough. - View Dependent Claims (6)

7. A method for approximating an object to an anatomical structure by at least one length of suture extending outwardly from a surface of said anatomical structure, wherein said object has a first surface and a second surface, said method comprising the steps of:
-
(a) providing suture retention means comprising; a substantially frusto-conical body having a longitudinal axis, a top surface, a bottom surface, a side surface and a longitudinally-centered cavity extending into said top surface; said top and bottom surfaces each (a) being substantially planar, (b) being oriented in spaced, parallel relation to one another, and (c) defining a substantially circular periphery centered about said longitudinal axis, said periphery of said bottom surface being smaller than said periphery of said top surface; said side surface extending between said periphery of said top surface and said periphery of said bottom surface; said longitudinally-centered cavity including a base surface, a sidewall surface and an open end; and said body further defining at least one opening extending from said bottom surface to said base surface, each said opening being sized so as to allow at least one free end of at least one length of suture to be threaded therethrough from said bottom surface into said longitudinally-centered cavity, and so as to prevent a knot formed by said at least one free end of suture from passing therethrough; (b) forming an opening in said object extending from said first surface to said second surface; (c) countersinking said opening in said object adjacent said first surface so as to form an inclined surface, with the countersunk region being sized so as to substantially completely accommodate said body when said side surface of said body is in engagement with said inclined surface; (d) locating said object and said anatomical structure in a predetermined position relative to one another, and passing said at least one free end of said at least one length of suture through at least a portion of said opening in said object so as to extend outwardly from said countersunk region; (e) locating said body in said countersunk region of said opening, with said at least one free end of said at least one length of suture extending through said at least one opening in said body, and tensioning said at least one length of suture; and (f) forming a knot in said at least one free end of said at least one length of suture such that said at least one length of suture is maintained under tension when said knot abuts the portion of said base of said cavity adjacent the opening with which said at least one free end of said at least one length of suture is associated. - View Dependent Claims (8, 9, 19, 20, 21, 22, 23, 24, 25, 26)

10. A method for approximating an object to an anatomical structure by at least one length of suture extending outwardly from a surface of said anatomical structure, wherein said object has a first surface and a second surface, said method comprising the steps of:
-
(a) providing suture retention means comprising; a substantially frusto-conical body having a longitudinal axis, a top surface, a bottom surface, a side surface and a longitudinally-centered cavity extending into said top surface; said top and bottom surfaces each (a) being substantially planar, (b) being oriented in spaced, parallel relation to one another, and (c) defining a substantially circular periphery centered about said longitudinal axis, said periphery of said bottom surface being smaller than said periphery of said top surface; said side surface extending between said periphery of said top surface and said periphery of said bottom surface; said longitudinally-centered cavity including a base surface, a sidewall surface and an open end; and said body further defining at least one opening extending from said side surface to said sidewall surface, each said opening being sized so as to allow at least one free end of at least one length of suture to be threaded therethrough from said side surface into said longitudinally-centered cavity, and so as to prevent a knot formed by said at least one free end of suture from passing therethrough. (b) forming an opening in said object extending inwardly from said first surface; (c) countersinking said opening in said object adjacent said first surface so as to form an inclined surface, with the countersunk region being sized so as to substantially completely accommodate said body when said side surface of said body is in engagement with said inclined surface; (d) forming a second opening in said object extending from said second surface to said inclined surface of said countersunk region; (e) locating said object and said anatomical structure in a predetermined position relative to one another, and passing said at least one free end of said at least one length of suture through at least a portion of said second opening in said object so as to extend outwardly from said countersunk region; (f) locating said body in said countersunk region of said opening, with said at least one free end of said at least one length of suture extending through said at least one opening in said body, and tensioning said at least one length of suture; and (g) forming a knot in said at least one free end of said at least one length of suture such that said at least one length of suture is maintained under tension when said knot abuts the sidewall surface of said longitudinally-centered cavity adjacent the opening with which said at least one free end of said at least one length of suture is associated.
