1. A tissue retention system comprising:
- a suture anchor comprising;
an elongated body having an exterior sidewall, a proximal end and an opposing distal end displaced from the proximal end along a longitudinal axis, wherein a first suture port and a separate second suture port extend through at least a portion of the body and the first suture port is independently fully encircled and uninterrupted by a first interior surface along a portion of its length and the second suture port is independently fully encircled and uninterrupted by a second interior surface along a portion of its length;
a channel near the proximal end of the elongated body, wherein the channel is formed within the exterior sidewall of the elongated body; and
a helical thread wound about and outwardly projecting from the elongated body;
wherein the channel is proximally recessed from the helical thread such that a suture may pass through a path defined by the first suture port, the channel, and the second suture port without intersecting the helical thread;
wherein at least a first portion of the first suture port extends substantially parallel to the longitudinal axis;
wherein the first suture port is spaced apart from the longitudinal axis so as to not intersect the longitudinal axis;
wherein the elongated body is formed as a single, unitary piece.

Abstract
A suture anchor includes an elongated shaft having an exterior sidewall extending between a proximal end and an opposing distal end. A helical first thread is wound about and outwardly projects from the exterior sidewall of the shaft so as to extend between the proximal end and the distal end of the shaft. A first suture port transversely extends through at least a portion of the first thread at the proximal end of the shaft. The suture port is configured to receive a suture line.

8. A tissue retention system comprising:
a suture anchor comprising; an elongated body having an exterior sidewall, a proximal end and an opposing distal end displaced from the proximal end along a longitudinal axis; a first suture port and a separate second suture port near the proximal end, wherein the first suture port is independently fully encircled and uninterrupted by a first interior surface along a portion of its length and the second suture port is independently fully encircled and uninterrupted by a second interior surface along a portion of its length, wherein each of the first and second suture ports extends through an exterior sidewall of the elongated body distal to the location; a channel near the proximal end of the elongated body, wherein the channel is formed within the exterior sidewall of the elongated body; and a helical thread wound about and outwardly projecting from the elongated body; wherein the channel is proximally recessed from the helical thread such that a suture may pass through a path defined by the first suture port, the channel, and the second suture port without intersecting the helical thread; wherein the first and second suture ports are positioned on either side of the longitudinal axis to independently retain first and second suture portions; wherein the elongated body is formed as a single, unitary piece. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A tissue retention system comprising:
a suture anchor comprising; an elongated body having an exterior sidewall, a proximal end and an opposing distal end displaced from the proximal end along a longitudinal axis, wherein a bore extends along the longitudinal axis through a portion of a longitudinal length of the body, wherein a first suture port extends through at least a portion of the body to receive a suture, wherein the first suture port is positioned such that the first suture port is not in communication with the bore; a channel near the proximal end of the elongated body, wherein the channel is formed within the exterior sidewall of the elongated body; and a helical thread wound about and outwardly projecting from the elongated body; wherein the channel is proximally recessed from the helical thread such that a suture may pass through a path defined by the first suture port, the channel, and the second suture port without intersecting the helical thread; wherein at least a portion of the bore is shaped to receive a distal end of a driver to facilitate transmission of torque from the driver to the suture anchor; wherein the elongated body is formed as a single, unitary piece. - View Dependent Claims (17, 18, 19, 20, 21, 22, 32)

23. A tissue retention system comprising:
a suture anchor comprising; an elongated body having an exterior sidewall, a proximal end and an opposing distal end displaced from the proximal end along a longitudinal axis, wherein a first suture port and a second suture port each extend through at least a portion of the elongated body; a channel near the proximal end of the elongated body, wherein the channel is formed within the exterior sidewall of the elongated body; and a helical thread wound about and outwardly projecting from the elongated body; wherein the channel is proximally recessed from the helical thread such that a suture may pass through a path defined by the first suture port, the channel, and the second suture port without intersecting the helical thread; wherein each of the first and second suture ports is configured to receive an intermediate suture portion such that the first and second suture ports cooperate to provide four parallel suture lengths extending proximally from four apertures of the proximal end, wherein each aperture is fully encircled by an interior surface of the elongated body; wherein the elongated body is formed as a single, unitary piece. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
