Embodiment Construction

[0041] Several challenges are faced in delivering suture anchor assemblies for use in soft tissue for bone repair. One such challenge is locating the point at which the suture anchor will be inserted into the bone. Typically, suture anchors are inserted into the bone in pre-prepared holes. While the general location of the bone hole is known, keeping the bone hole precisely aligned with the delivery path of the anchor assembly can be difficult given the small size of the anchor assembly and limited visibility within the surgical site. Accordingly, a suture anchor assembly that has the ability to locate a bone hole within a defined area in which the hole is known is located is desirable.

[0042] Another such challenge is maintaining a clear delivery path for the suture anchor assembly to the bone hole. As the connection between the soft tissue and bone becomes weakened or severed in the repair area, the soft tissue and bone can shift during surgery, obstructing the delivery ...

Abstract

The suture anchor assembly includes a suture anchor and a suture anchor insert. The anchor includes a flexible distal tip and a rigid proximal anchor body. The distal tip includes a transverse suture eyelet and a cavity formed in the proximal end of the tip. The anchor body includes a lumen extending between proximal and distal ends of the body. The anchor insert includes a tubular outer shaft and an inner insert slidably received therein. The anchor assembly is actuatable to move the anchor tip and inner shaft proximally while the outer shaft and anchor body remain in place, thereby pressing the proximal end of the anchor tip against the distal end of the anchor body superior. The proximal end of the tip is deformable to receive at least a portion of the distal end of the anchor body within the anchor tip cavity.

Description

Background technique [0001] Suture anchors are employed during surgical repair procedures to secure the suture in a desired position relative to the patient's bone. Typically, one or more slip knots are formed in the suture to secure the suture to the anchor. However, slipping knots can be difficult and / or time-consuming, especially when performing arthroscopic procedures. Accordingly, there is an ongoing need for improved suture anchors and corresponding delivery systems that do not rely on sliding suture knots to secure the suture to the anchor. Contents of the invention [0002] In an embodiment, a suture anchor assembly is provided. The suture anchor assembly includes a suture anchor and an anchor insert. The suture anchor includes an elongate anchor body having a lumen extending through the elongate anchor body along a longitudinal axis between a proximal end and a distal end. The suture anchor further includes an anchor tip having a proximal end and a distal end, t...
