Publication number: 20220008063Abstract: Methods and devices are provided for anchoring suture to bone. In one exemplary embodiment, a suture anchor is provided that includes one or more bone-engaging surfaces features and an external sidewall. The external sidewall can allow a suture coupled to the suture anchor and located between the anchor and bone to be movable relative to the suture anchor, even when the suture anchor is partially or fully disposed within a bone hole. Suture threaders and suture anchor drivers are also provided that can be used with the various methods and devices disclosed herein, or with other methods and devices known in the art.Type: ApplicationFiled: September 24, 2021Publication date: January 13, 2022Inventors: Douglas Hester, Brian Otrando

Patent number: 10390822Abstract: Various exemplary surgical fasteners are provided, and methods and devices are provided for deploying a surgical fastener. In general, the methods and devices allow a surgical fastener to be deployed to secure tissue to bone. In one embodiment, a surgical fastener can be configured to move between a first linear or compressed configuration, in which the fastener can have a first maximum diameter, and a second bent or expanded configuration, in which the fastener can have a second maximum diameter greater than the first maximum diameter. A delivery device can be configured to advance the fastener through tissue and into bone to attach the tissue to the bone. The delivery device can be configured to maintain the fastener in the compressed configuration such that when the fastener is released from the delivery device, the fastener can be configured to self-expand from the compressed configuration to the expanded configuration.Type: GrantFiled: March 11, 2016Date of Patent: August 27, 2019Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Douglas Hester, Joyce-Marie Gallagher

Patent number: 10292699Abstract: Devices, systems, and methods are provided for managing suture filaments when performing soft tissue repair. One exemplary embodiment of a surgical suture management device is in the form of a suture loop management card. The card can generally be configured to hold open a collapsible loop of suture until a force applied to the loop is greater than a threshold tension. The card can include a number of different features that help to keep the loop open until the threshold tension is achieved, including features designed to prevent the filament from being mistakenly offloaded. The card can be configured to be removably inserted into a handle of an inserter tool for use as a surgical tissue repair system. Other devices, systems, and methods for performing soft tissue repair are also provided.Type: GrantFiled: December 2, 2016Date of Patent: May 21, 2019Assignee: MEDOS INTERNATIONAL SÀRLInventors: James T.

Publication number: 20160089193Abstract: A method of compacting and stabilizing bone in the spine using an expandable screw and bone filler. The method comprises placing an expanding screw through a pedicle and into a fractured vertebral body using established techniques; and expanding the screw within the body to create a cavity by tamping bone around the expanded aspect of the screw. The screw can be expanded and rotated about its rotational-axis to tamp bone adjacent to the expanded screw. After compaction, the screw is removed and the cavity is filled with bone filler.Type: ApplicationFiled: December 8, 2015Publication date: March 31, 2016Applicant: DePuy Synthes Products, Inc.Inventors: Michael A.

Patent number: 8579910Abstract: A spinal implant insertion device is hereby provided. The device includes an insertion blade assembly having a set of opposed insertion blades wherein the assembly is adapted to slide from a retracted position to an extended position relative to an elongate shaft. In the extended position, a blades are adapted to be positioned above and below a portion of a spinal implant so as to shield the portion of the implant during delivery to an intervertebral space. The insertion blades assembly can also be modular so as to utilize a wide range of distinct insertion blades. Additionally, a method for delivering a spinal implant to an intervertebral space is herein provided. Like above, the method utilizes an insertion blade assembly adapted to slide along a shaft of a spinal implant insertion device.Type: GrantFiled: May 18, 2007Date of Patent: November 12, 2013Assignee: DePuy Synthes Products, LLCInventors: Douglas Hester, Paul S.

Publication number: 20110077655Abstract: A mandrel is inserted into the tissue to be distracted and a filament is repeatedly wrapped around the mandrel to make a spool. As the mandrel turns, the filament coils around the mandrel to create of spool of increasing diameter. This spool can be used as a distractor, tamp, or implant. A spool implant can be cemented to further stabilize the device in situ, such as a vertebral body. The filament deposition upon the mandrel is controlled by rotation and the volume creation is incremental. This makes the spool ideal for creating highly controlled distraction forces or insertion of bulking material. In some embodiments, fibers having a low glass transition temperature are used.Type: ApplicationFiled: September 23, 2010Publication date: March 31, 2011Inventors: Michael A. Fisher, Thomas M.
