Benefits of technology

The present invention is an anchor for securing a suture in the body. The suture anchors of the present invention are usable in soft tissue as well as in bone. 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.

Problems solved by technology

Most current suture anchors, especially those for anchoring in bone, are not easily removable.

Embodiment Construction

The present invention relates to a suture anchor and particularly to an anchor for anchoring a suture to body tissue such as bone and to a method for such anchoring and removal. The present invention is applicable to various anchor constructions. As representative of the present invention, FIG. 1 illustrates a suture anchor 10. The anchor 10 is a cylindrical member with a tubular wall 12 extending about a longitudinal axis 14 of the anchor. The wall 12 has a cylindrical outer surface 16 and a cylindrical inner surface 18. The inner surface 18 of the anchor 10 defines a cylindrical central channel 20 extending longitudinally through the anchor 10.

The anchor 10 has a first end portion indicated generally at 30, a second end portion indicated at 32, and an intermediate portion indicated generally at 34. The present description assumes that the first end portion 30 will be inserted into the body tissue as the leading end portion of the anchor 10. For purposes of the present description,...

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.

Description

BACKGROUND OF THE INVENTION1. Technical FieldThe present invention relates to the arts of medicine and surgery, and more particularly relates to apparatus and method for securing a suture in body tissue.2. Description of the Prior ArtSuture anchors have been developed for anchoring sutures during open surgery and arthroscopic surgery with single side access. With a suture anchored in tissue, it is possible to apply force to the suture to hold other body tissue or implanted devices.It is desirable that a suture anchor be as small as possible in order to minimize damage to the tissue in which the suture is anchored. It is also desirable that a suture anchor be easily attached, hold the suture firmly in place, and be easily removable without trauma. Most current suture anchors, especially those for anchoring in bone, are not easily removable.SUMMARY OF THE INVENTIONThe present invention is an anchor for securing a suture in the body. The suture anchors of the present invention are usab...
