20110071641 | Articular Surface Implant and Delivery System - A method is provided for delivering an implant for replacing a portion of an articular surface. The method may include forming a socket in an articulating feature that is capable of moving relative to the articular surface. An implant may be placed in the socket and the articulating feature may be moved relative to the articular surface to generally align the socket with an implant site formed in the articular surface. The implant may be transferred from the socket into the implant site. | 03-24-2011 |
20110152870 | Retrograde Delivery of Resurfacing Devices - A method according to one embodiment may provide access to an articular surface of a bone. The method includes forming a passage through at least a portion of the bone. The passage provides an opening in the articular surface. The method further includes inserting a tether through the passage. The tether inserted through the passage can be coupled to at least one device from an insertion site remote from the articular surface. The tether can be withdrawn through the passage to convey the device to a location proximate the articular surface. | 06-23-2011 |
20110196434 | SYSTEM AND METHOD FOR RETROGRADE PROCEDURE - A system and method may be used for accessing an articular surface and for preparing an implant site on the articular surface. The method may include locating a portion of the articular. An access passage may be drilled towards the articular surface though bone behind the articular surface. An implant site may be excised in the articular surface relative to an axis defined by the access passage. | 08-11-2011 |
20140066933 | Devices, Apparatuses, Kits, and Methods for Repair of Articular Surface and/or Articular Rim - Embodiments of devices, apparatuses, kits, and methods for repairing and/or augmenting the articular surface and/or articular rim of a joint (e.g., repairing the anterior glenoid rim after an anterior shoulder dislocation). | 03-06-2014 |

20090042294 | Hydroxyphenyl cross-linked macromolecular network and applications thereof - A dihydroxyphenyl cross-linked macromolecular network is provided that is useful in artificial tissue and tissue engineering applications, particularly to provide a synthetic macromolecular network for a wide variety of tissue types. In particular, artificial or synthetic cartilage, vocal cord material, vitreous material, soft tissue material and mitral valve material are described. In an embodiment, the network is composed of tyramine-substituted and cross-linked hyaluronan molecules, wherein cross-linking is achieved via peroxidase-mediated dityramine-linkages that can be performed in vivo. The dityramine bonds provide a stable, coherent hyaluronan-based hydrogel with desired physical properties. | 02-12-2009 |

20100274356 | APPARATUS AND METHOD FOR SEQUENTIALLY ANCHORING MULTIPLE GRAFT LIGAMENTS IN A BONE TUNNEL - An apparatus for anchoring at least two graft ligaments within a longitudinal bone tunnel includes a longitudinal sleeve having at least two radially spaced ligament-contacting surfaces located in lateral opposition to a sleeve inner lumen. The sleeve is configured for at least partial insertion into the bone tunnel with each graft ligament positioned laterally adjacent a different ligament-contacting surface. The graft ligaments are at least partially located between the bone tunnel and the sleeve. An actuating member has longitudinally separated proximal and distal actuating member ends. An asymmetrically offset profile is defined by at least one of the sleeve and the actuating member. The asymmetrically offset profile has a plurality of longitudinally spaced engagement thresholds. The actuating member is inserted longitudinally into the sleeve to cause frictional engagement of each graft ligament with both the bone tunnel and at least one ligament-contacting surface. The frictional engagement of each graft ligament is temporally spaced apart from the frictional engagement of at least one other graft ligament. The temporal spacing is provided by the plurality of engagement thresholds. A method of anchoring at least two longitudinally extending graft ligaments within a bone tunnel is also provided. | 10-28-2010 |
20130297021 | APPARATUS AND METHOD FOR SEQUENTIALLY ANCHORING MULTIPLE GRAFT LIGAMENTS IN A BONE TUNNEL - An apparatus for anchoring at least two graft ligaments within a longitudinal bone tunnel includes a longitudinal sleeve having at least two ligament-contacting surfaces located in lateral opposition to a sleeve inner lumen.

An actuating member has proximal and distal actuating member ends. An asymmetrically offset profile is defined by the sleeve and/or the actuating member. The asymmetrically offset profile has engagement thresholds. The actuating member is inserted into the sleeve to cause frictional engagement of each graft ligament with both the bone tunnel and at least one ligament-contacting surface, the frictional engagement of each graft ligament being temporally spaced apart from the frictional engagement of at least one other graft ligament. | 11-07-2013 |
20150045886 | APPARATUS AND METHOD FOR SEQUENTIALLY ANCHORING MULTIPLE GRAFT LIGAMENTS IN A BONE TUNNEL - An apparatus for anchoring elongate strands within a longitudinal tunnel is disclosed. At least two cams are arranged longitudinally adjacent each other along a longitudinal axis. A first anchor member includes a first cam-contacting surface and a first strand-contacting surface. The first cam-contacting surface is selectively operatively connected to a first cam. A second anchor member includes a second cam-contacting surface and a second strand-contacting surface. The second cam-contacting surface is selectively operatively connected to a second cam. An elongate strand is positioned between the tunnel wall and the first or second strand-contacting surfaces. Rotation of a selected cam causes the selected cam to selectively apply a force to a corresponding first or second cam-contacting surface to urge the corresponding first or second strand-contacting surface away from the longitudinal axis to produce frictional engagement of the elongate strand with both a tunnel wall and the first or second strand-contacting surface. | 02-12-2015 |
