Benefits of technology

[0010] The continuous suture loop of the anchor provides strength and a flexible eyelet, which can ease the process of threading a suture through the eyelet during a surgical procedure. According to one aspect of the present invention, at least a portion of an outer surface of the continuous suture loop is bonded to an inner surface of the bore of the body.

Problems solved by technology

The devices discussed above are fairly time consuming and complicated to fasten the soft tissue against the bone mass.
It is also difficult for these devices to keep the soft tissue tightly attached to the bone mass during the body's healing process.

Embodiment Construction

[0031] Suture anchors constructed in accordance with the present invention are primarily for use in orthopedic surgery for securing soft tissue to bone, though such anchors may be used in other fields as appropriate. As illustrated in FIG. 1, one suture anchor 10 includes an elongated body 12 which extends along a longitudinal axis X between a first end 14 and a second end 16. The elongated body 12 also includes an external threaded portion 18, and a drive head 20 at the second end 16. The elongated body 12 of FIGS. 1 and 2 also includes a bore 24 extending along the longitudinal axis X from the second end 16 towards the first end 14. FIG. 2 illustrates the anchor 10 received in bone 26.

[0032] As also shown in FIG. 2, the anchor 10 includes a continuous suture loop 30 secured within the bore 24 of the body 12 so that at least a portion of the loop 30 extends from the second end 16 of the body 12 to form an eyelet 32. In the embodiment of FIGS. 1 and 2, at least a portion of an oute...

Abstract

A suture anchor for securing soft tissue to bone, including a body and a continuous suture loop. The body extends along a longitudinal axis between opposing first and second ends, and has an external threaded portion extending coaxial with the axis, and a bore extending from the second end towards the first end. The continuous suture loop is secured within the bore of the body so that at least a portion of the loop extends from the second end of the body to form an eyelet.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority to provisional U.S. patent application Ser. No. 60 / 231,859, filed on Sep. 12, 2000, which is assigned to the assignee of the present application and incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention generally relates an apparatus and method for securing suture to bone, and more particularly, to suture anchors for securing soft tissue to bone. BACKGROUND OF THE INVENTION [0003] When soft tissue tears away from bone, reattachment becomes necessary. Various devices, including sutures alone, screws, staples, wedges, and plugs have been used in the past to secure soft tissue to bone. [0004] Recently, various types of threaded suture anchors have been developed for this purpose. Some threaded suture anchors are designed to be inserted into a pre-drilled hole. Other suture anchors are self-tapping. [0005] U.S. Pat. No. 4,632,100 discloses a cylindrical threaded suture a...
