Abstract

The present invention is an anchor for securing a suture in the body. The anchor includes a tubular wall having a central axis. The tubular wall has a proximal end and a distal end each free of axially inwardly extending slots. The tubular wall has an inner surface extending for the entire length of the tube and defining in the anchor a central opening extending between the proximal end and the distal end. The anchor has a width less than its length. A suture may extend through the anchor within the central opening. First and second end portions of the suture extend out of opposite ends of the anchor and are sufficiently long to project out of the body when the suture is secured in the body by the anchor. The anchor has an anchoring orientation in the body achieved by manipulation of the distal end of the anchor by pulling on the second end portion of the suture. The anchor has a removal orientation in the body achieved by manipulation of the proximal end of the anchor by pulling on the first end portion of the suture. The present invention also relates to a method of anchoring to a bone a suture having first and second end portions.
