20140074163 | SUTURE ANCHORS AND ASSEMBLIES FOR ATTACHING SOFT TISSUE TO BONE - Improved bone anchors are disclosed for anchoring one or more sutures attached to soft tissue to a bone. The bone anchor has an anchor body that extends between a distal and a proximal end. A bore is formed axially in the anchor body and opens at the proximal end. One or more pins are fixed within the bore of the anchor body. One or more sutures can be looped on the pins for anchoring soft tissue to bone. The anchor body has a socket within the bore for receiving a driver tool. The distal end of the anchor body forms a non-threaded extension, which stabilizes the bone anchor, and helps prevent lateral movement during use. In one embodiment, the anchor body has coarse threads for engaging soft bone tissue and fine threads for engaging hard bone tissue. | 03-13-2014 |

20120143250 | BONE ANCHORS WITH THREAD PATTERN OPTIMIZED FOR ATTACHMENT TO HARD AND SOFT BONE TISSUE - Bone anchors useful in rotator cuff repair optimize the thread pattern for engaging different types of bone tissues, including harder cortical bone and softer cancellous bone. Bone anchors may include fine threads for engaging cortical bone and coarse threads for engaging cancellous bone. Threads can be made finer by increasing root diameter and surface angle of the threads. The pitches of the fine and coarse threads are kept the same, which allows fine threads to follow the impression created by coarse threads as the anchor is driven into a bone. Threads that engage cortical bone can be multi-fluted and include a first flute that follows the same thread pattern as coarse threads such that first flute follows the groove created by the coarse threads as the bone anchor is driven into a bone. Bone anchors can have a distal non-threaded stabilizing extension at the distal end. | 06-07-2012 |
20100106153 | ELECTROSURGICAL INSTRUMENT WITH AN ABLATION MODE AND A COAGULATION MODE - Electrosurgical instruments are configured to selectively perform ablation or coagulation as desired. The electrosurgical instruments include at least two electrodes on the electrode probe that can be activated using an RF generator. The electrosurgical instruments are selectively switchable between an ablation mode and a coagulation mode by changing the amount of active electrode surface area. In particular, in the ablation mode, a relatively small electrode surface area is active. Thus, for a given power input, the current density is relatively high. In the coagulation mode, the active electrode surface area is increased, thereby reducing the current density in the coagulation mode for the given power input. | 04-29-2010 |

20090082806 | MENISCAL REPAIR SYSTEM - A meniscal repair system including a pair of elongate needles with a suture filament attached between respective proximal ends of the needles. Two implants are attached to the suture (e.g., molded thereon) between the needles so as to form a suture bridge between the implants. One implant may comprise a barbed shaft aligned with the suture, while the other may be in the form of a T-bar that can be deployed so as to be perpendicular to a portion of the suture filament. The system may further include one or more dilators (e.g., one or more suture knots or molded beads) disposed along the length of the suture filament to aid in passage of the implant after the associated needle. | 03-26-2009 |
