Patent number: 7740657Abstract: A sheath for organizing soft tissue includes a first tube having a flexible body sized and shaped to receive a fixation device, and a second tube coupled to the first tube having a flexible body sized and shaped to receive a soft tissue graft. A method for implanting soft tissue in a bone tunnel includes coupling a soft tissue graft to a sheath assembly; and positioning the sheath assembly relative to the soft tissue graft based on a measured depth of a bone tunnel. A set of surgical devices for implanting soft tissue grafts in a bone tunnel includes a sheath assembly, a measurement device for measuring the depth of the bone tunnel, a securing element configured to secure the sheath assembly to the soft tissue graft at a position determined by the measured bone tunnel depth, and a tensioning device configured to organize a plurality of soft tissue grafts.Type: GrantFiled: October 3, 2007Date of Patent: June 22, 2010Inventors: Charles H. Brown, Jr., Bernard J. Bourque, Rebecca A. Blough, Michael C. Ferragamo, Raymond A. Bojarski, Paul Alexander Torrie, Ben K. Graf, Fraser Harvie, Steve Ek

Publication number: 20100152851Abstract: A ligament incorporated into a prosthetic joint exhibiting a plasticized, elongated and deformable material. A fibrous material is internally disposed within the deformable material, the fibrous material terminating in first and second enlarged bead portions arranged in proximity to enlarged pocket defined ends associated with the deformable materials. First and second bones define a joint region therebetween, the deformable end pockets and bead portions being inserted through associated holes defined in joint proximate locations associated with the bones, so that actuation of a projection location of the fibrous material causes the bead portions to outwardly deflect the end pockets, resulting in the ligaments being anchored in place between the bones.Type: ApplicationFiled: February 18, 2010Publication date: June 17, 2010Applicant: LINARES MEDICAL DEVICES, LLCInventor: Miguel A. Linares

Publication number: 20100152850Abstract: Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.Type: ApplicationFiled: December 9, 2009Publication date: June 17, 2010Applicant: CAYENNE MEDICAL, INC.Inventors: Kenneth D.

Publication number: 20100145449Abstract: A system for manipulating energy transferred by members defining a joint. The system includes a first attachment structure configured to be attached to a first member of the joint and a second attachment structure configured to be attached to a second member of the joint. There is also an adjustable energy absorbing device attached to the first attachment structure and second attachment structure, wherein adjusting the energy absorbing device changes the load manipulating characteristics of the energy absorbing device.Type: ApplicationFiled: February 5, 2010Publication date: June 10, 2010Applicant: Moximed, Inc.Inventors: Joshua Makower, Anton G.
