Patent number: 10369255Abstract: The present invention generally relates to nanoscale wires and tissue engineering. In various embodiments, cell scaffolds for growing cells or tissues can be formed that include nanoscale wires that can be connected to electronic circuits extending externally of the cell scaffold. The nanoscale wires may form an integral part of cells or tissues grown from the cell scaffold, and can even be determined or controlled, e.g., using various electronic circuits. This approach allows for the creation of fundamentally new types of functionalized cells and tissues, due to the high degree of electronic control offered by the nanoscale wires and electronic circuits. Accordingly, such cell scaffolds can be used to grow cells or tissues which can be determined and/or controlled at very high resolutions, due to the presence of the nanoscale wires, and such cell scaffolds will find use in a wide variety of novel applications, including applications in tissue engineering, prosthetics, pacemakers, implants, or the like.Type: GrantFiled: July 21, 2016Date of Patent: August 6, 2019Assignees: President and Fellows of Harvard College, Massachusetts Institute of Technology, Children's Medical Center CorporationInventors: Charles M.

The free suture ends are wrapped about a suture cleat on an inserter handle once the desired tension level is achieved. A proximal anchor component is moved distally to engage with a distal anchor component to lock the anchor in place within the bone hole, and to lock the suture in place within the anchor. Then, the inserter is removed from the procedural site.Type: GrantFiled: December 31, 2008Date of Patent: March 29, 2016Assignee: Cayenne Medical, Inc.Inventors: Jordan A. Hoof, Kevin S. Nason

Patent number: 8778023Abstract: A graft ligament anchor includes a tubular body having a bore therethrough and proximal and distal ends. A flange is attached to the tubular body at the proximal end thereof and extends radially outwardly beyond the tubular body. A deformable wall is disposed in the tubular body bore and defines, at least in part, a chamber for retaining the graft ligament therein. An expansion device is configured for insertion into the tubular body axially of the tubular body, and for impinging upon the deformable wall to press the deformable wall, and hence the graft ligament received in the chamber, toward a wall of the bore, whereby to fix the graft ligament in the tubular body.Type: GrantFiled: November 23, 2010Date of Patent: July 15, 2014Inventor: Joseph H. Sklar

Patent number: 8753391Abstract: An implantable device is provided for soft-tissue or soft tissue-to-bone repair, fixation, augmentation, or replacement that includes a biomimetic and biodegradable nanofiber scaffold. Also provided is a fully synthetic implantable multiphased scaffold which includes, in a single continuous construct, a plurality of phases to mimic the natural anatomy of a tendon or ligament and their insertion sites. Also provided are scaffold apparatuses for musculoskeletal tissue engineering.Type: GrantFiled: August 12, 2009Date of Patent: June 17, 2014Assignee: The Trustees of Columbia University in the City of New YorkInventors: Helen H. Lu, Jeffrey Spalazzi

Patent number: 8747470Abstract: Various methods and devices are provided for a graft fixation device for fixing a graft member within a bone tunnel. In one embodiment, a graft fixation device is provided having a radially expandable sheath adapted to be disposed within a bone tunnel, and a sheath expander adapted to be received within the radially expandable sheath to expand the sheath and thereby anchor a graft between the sheath and the bone tunnel. In an exemplary embodiment, the graft fixation device is particularly useful to affix a graft within a femoral tunnel.Type: GrantFiled: June 26, 2012Date of Patent: June 10, 2014Assignee: DePuy Mitek, LLCInventors: Charles Beck, Jr., Jose E. Lizardi

Publication number: 20140156004Abstract: Pathology of the human knee can arise from excessive and/or uneven loading of regions within the joint. Methods and apparatus are disclosed that enable displacement of soft tissue around the knee, without displacing or severing bone thereby altering the mechanical load distribution within the joint in a less invasive manner than previous techniques.Type: ApplicationFiled: February 7, 2014Publication date: June 5, 2014Applicant: Cotera, Inc.Inventors: Vivek Shenoy, Hanson S. Gifford, II
