Publication number: 20120253389Abstract: A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose with first and second noose limbs connected, preferably slidably, to the filament engagement feature. The first and second noose limbs emerge from the anchor as first and second free filament limbs that are capable of being passed through tissue to be repaired and then passable through the noose. The noose is capable of receiving the free filament limbs and strangulating them when tension is applied to at least one of the free filament limbs and the noose to enable incremental tensioning of the tissue after anchor fixation. Preferably, the snare assembly further includes a flexible sleeve joining at least some portion of the first and second free filament limbs to facilitate passing of the free filament limbs as a single unit.Type: ApplicationFiled: March 30, 2012Publication date: October 4, 2012Applicant: DePuy Mitek, Inc.Inventors: Mehmet Ziya Sengun, Howard Tang, David B.

Publication number: 20120184992Abstract: A bioabsorbable suture anchor for anchoring soft tissue to a bone is provided. The suture anchor is configured to toggle and anchor itself inside a bone cavity of a small joint. The anchor comprises an elongate body defined by a longitudinal axis, a first, leading end and a second, trailing end. The elongate body also has two opposed surfaces between the first and second ends, and a plurality of sidewalls extending between the two opposed surfaces. Extending from one of the sidewalls is a flared portion that is formed on the second end of the elongate body. A suture channel extends between the two opposed surfaces.
