20090248068 | Non-metallic knotless suture anchor - A polymeric suture anchor for deployment in a preformed bone hole to secure soft tissue to bone in a knotless manner. The suture anchor comprises a hollow outer member and a hollow inner member longitudinally movable within the outer member. Suture is directed along a tortuous path distally through the lumens of both the inner and outer members, transversely across an eyelet situated at the distal end of the inner member and proximally through the lumens of both the inner and outer members. A suture-locking mechanism is provided along the tortuous path to crimp the suture by placing the anchor in a suture locked configuration. This is accomplished by moving the inner member proximally relative to the outer member in order to engage the suture-locking mechanism. The anchor is maintained in this configuration by the engagement of interlocking surfaces on the inner and outer members. Simultaneously, the inner member is provided with radially outwardly extending prongs which pass through slots in the outer member in order to engage bone surrounding the bone hole. | 10-01-2009 |
20090270886 | Hollow suture needle with handle - A suture needle instrument having improved connection means enabling a hollow suture needled to be attached to a handle in a variety of orientations. The suture needle is provided with user accessible suture channels and suture advancing wheels to facilitate cleaning and repair. | 10-29-2009 |
20090318964 | KNOTLESS SUTURE ANCHOR - An anchoring device for deployment in a pre-formed hole to secure soft tissue to bone. Embodiments of the anchoring device include an outer member and an inner member that moves relative to the outer member from a suture-unlocked position to a suture-locked position. The inner member further includes an elongated projection with a proximal end that defines an outer dimension. In one embodiment, the elongated projection is configured to interface with a portion of the outer member so as to change the outer dimension in a manner that causes the elongated projection to displace a portion of the bone. | 12-24-2009 |
20110224726 | SUTURE ANCHOR - There is described a suture anchor with anchor members moveable as between a suture-unlocked configuration and suture-locked configuration. In one embodiment, the anchor members include an outer anchor member with features, e.g., flexible barbs, configured to secure the suture anchor in the suture-locked configuration to material proximate a pre-formed hole in bone material. The outer anchor member is also configured with a bore to receive suture material, and which is sized and shaped to receive an inner anchor member therein. The inner anchor member includes securing features such as projections that compress the suture material against the surface of the bore when the suture anchor is actuated from the suture-unlocked configuration to the suture-locked configuration. | 09-15-2011 |
20120109194 | Suspensory graft fixation with adjustable loop length - A suspensory graft ligament fixation device is shown to be particularly suitable for maximizing the contact between a soft tissue graft and the bone tunnel prepared to receive the graft. The suspensory fixation device has an elongated anchor member adapted to be transversely situated at the exit of the bone tunnel. A loop member is suspended transversely from the anchor member and has a loop length which is adjustable. When a graft ligament is attached to the saddle end of the loop, the length of the loop member may be shortened to pull the graft member into the bone tunnel until it bottoms out at the floor of the bone tunnel. | 05-03-2012 |
20120290004 | SOFT ANCHOR MADE FROM SUTURE FILAMENT AND SUTURE TAPE - An anchor is provided for placement in or against tissue. The anchor includes a fibrous construct and at least a first filament. Each filament passes through the construct in at least three passing locations including a first location nearest a first end of the construct, a last location nearest a second end of said construct, and at least one intermediate location between said first passing location and said last passing location. In an undeployed state, each filament extends a first length between said first location and said last location. In a deployed state, each filament extends a second length between the first location and the last location. The second length is shorter than said first length. | 11-15-2012 |
20130018416 | SOFT SUTURE ANCHOR MADE OF BRAIDED OR MONOFILAMENT SUTURE - A soft suture anchor is described that includes a first section of suture bent to define a first vertex separating a first standing end and a second standing end. The first standing end and the second standing end being legs of an acute angle. A second section of suture circumscribes the first standing end and the second standing end with at least one wrap. A first end of said second section is wrapped a plurality of times about the first standing end, and a second end of the second section is wrapped a plurality of times about the second standing end. | 01-17-2013 |
20140257383 | All-suture anchor inserter - This invention pertains to the percutaneous insertion of a soft, non-rigid suture anchor construct preloaded onto an inserter which is “self-punching”. The preferred embodiment of soft suture anchor disclosed herein is a suture anchor which is entirely comprised of filaments of compressible, distendable, soft materials such as commonly used suture materials. The inserter is adapted to not only carry the all-suture anchor into a bony substrate, but is also capable of forming a hole in the bone, to receive the anchor, in the same step. | 09-11-2014 |
