20090198288 | SELF-TAPPING BIOCOMPATIBLE INTERFERENCE BONE SCREW - A biocompatible interference screw for soft tissue or bone-to-bone fixation comprises a screw body extending from a screw head to a distal tip of the screw. The screw body has an outer surface, and comprises polyether-ether-ketone (PEEK) material. Advantageously, the body outer surface has a textured surface finish for substantially improving pull-out strength of the interference screw. The textured surface finish is textured, in preferred embodiments, with a minimum of approximately 16 micro inches of surface roughness. The screw head comprises a tapered square keyhole for receiving a distal end of a driver instrument. The screw comprises a series of threads, which have a relatively smooth profile, in order to prevent graft tissue laceration as the screw is being inserted. The distal tip of the screw body comprises a narrow tip, and a distal end of the screw body is angled inwardly toward the narrow distal tip. | 08-06-2009 |
20100106169 | MENISCAL REPAIR SYSTEMS AND METHODS - A device for repairing a tear in a portion of tissue comprises a proximal actuator portion, a transfer needle extending distally from the proximal actuator portion and a catch needle extending distally from the proximal actuator portion. A suture needle is disposed in the transfer needle, and is extendable from the transfer needle toward the catch needle and retractable from the catch needle toward the transfer needle. An extendable catch plunger is disposed in the catch needle for capturing suture therein when it is transferred from the transfer needle. A retractable insertion sheath is provided for covering the transfer needle and the catch needle when the device is inserted into a procedural site. A depth limiting apparatus limits the depth of insertion of the needle into the procedural site. | 04-29-2010 |
20100185283 | METHODS AND SYSTEMS FOR MATERIAL FIXATION - A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression. Graft strength has been found to be greater than 1,000 N (Newtons), which is desirable for ACL reconstruction systems. | 07-22-2010 |

The suture pinch ramp has a depth approximately equal to the predetermined depth at a distal end thereof and sloping outwardly in a proximal direction so that a depth of a proximal end of the suture pinch ramp approaches zero. An insertion member includes an insertion tube and a handle which is engageable with the anchor body to deploy the anchor in a selected bone site. | 04-25-2013 |

20140107700 | SYSTEMS AND METHODS FOR REPAIRING SOFT TISSUES USING NANOFIBER MATERIAL - An anchoring system is a combination of a nanofiber scaffold material and an arthroscopically deployable suture anchor. The anchor is deployed into a bone tunnel using common techniques. The nanofiber material extends out of the proximal end of the implant, once deployed. The implant also includes pre-loaded sutures or has the ability to accept and lock sutures to the implant. For an implant pre-loaded with suture, the implant is placed into the bone, the material is deployed above the anchor onto the surface of the bone, suture is passed through the soft tissue, and knots are tied to secure the tissue against the bone, sandwiching the material between the bone and tissue, to provide a pathway for cells from the bone marrow to the soft tissue-bone interface, promote the healing response, provide a biomimetic structure that cells readily adhere to, and create a larger healing footprint. | 04-17-2014 |
