Benefits of technology

The one-piece embodiment can be installed as described above. That is the spike or plug can be inserted through the soft tissue and then into the bone with the stop means grabbing the tissue and attaching or reattaching same to the bone mass. In the alternative, the stop means of the one-piece device can

Problems solved by technology

The use of bone tunnels for repair can be difficult and generally require large open incisions.
The unique knotless suture anchor assemblies described herein facilitate this difficult and precise procedure.
The process of passing the anchored suture through the soft tissue and tying a knot is time consuming and difficult to undertake in the tight space encountered during endoscopic surgery and sometimes even in conventional open surgery.
A few of these syst

Embodiment Construction

Referring now to FIG. 1, the knotless two-piece suture anchor assembly of the present invention contains as one integral component a hollow anchoring sleeve for installation and attachment to a bone mass. The hollow anchoring sleeve 1, as shown in FIG. 1a, is cylindrical in shape and possesses ribs or threads on its exterior. The device can also contain or be configured with prongs, umbrella spokes, have threads, be expandable, or have wedges, on its exterior, for secure attachment with the bone mass. These exterior attachment features are known to the industry and incorporated herein by reference.

FIG. 1b illustrates an alternate embodiment of the hollow anchoring sleeve 2 having a collar 3 to control depth of bone penetration. The collar prevents the sleeve from being forced too deep into the bone mass when the spike or plug member is inserted.

FIG. 1c illustrates an alternate embodiment of the hollow anchoring sleeve 4 wherein the sleeve has a pointed closed end 5 for ease of penet...

Abstract

A one-piece or two-piece knotless suture anchor assembly for the attachment or reattachment or repair of tissue to a bone mass. The assembly allows for an endoscopic or open surgical procedure to take place without the requirement of tying a knot for reattachment of tissue to bone mass. In one embodiment, a spike member is inserted through tissue and then inserted into a dowel-like hollow anchoring sleeve which has been inserted into a bone mass. The spike member is securely fastened or attached to the anchoring sleeve with a ratcheting mechanism thereby pulling or adhering (attaching) the tissue to the bone mass.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to devices or assemblies used in tissue repair. More particularly, the assembly enables the attachment together or repair of portions of biological tissue (i.e., tendons or ligaments) onto a bone surface.2. Description of the Background ArtSoft tissues, such as tendons and ligaments, generally are attached to bone by small collagenous fibers. These connections are strong but permit the tendons and ligaments to be flexible. When a tissue is torn away from the bone and requires repair, a surgeon is often required to repair the detached soft tissue with sutures which are passed through bone tunnels and tied. A number of devices have been developed for securing a ligament or tendon to a bone mass. These devices can be used in place of bone tunnelling techniques. These attachment devices are usually inserted through extensive surgical incisions and, in some circumstances, by arthroscopic surgical techniques...
