  • Publication number: 20250073016
    Abstract: An orthopedic attachment system such as a suture anchor system. The suture anchor system may include a suture anchor having a body portion with an aperture disposed therethrough. The suture anchor system may include a composite medical suture at least partially disposed in the aperture of the suture anchor. The composite medical suture may include a first plurality of fibers comprising a bioresorbable hyaluronan-based polymer and a second plurality of fibers comprising a non-resorbable polymer. Methods of using the orthopedic attachment system and making the medical textile are also disclosed.

  • Patent number: 12161347
    Abstract: Apparatuses and methods for microfracture (e.g., forming a plurality of microfractures in a bone to encourage cartilage regeneration). Some of the present apparatuses and methods are configured to create microfractures with smaller transverse dimensions (e.g., diameters) and greater depths than previously known. Some of the present apparatuses and methods comprise a penetrator removal tab coupled to the penetrator and configured to retract the penetrator relative to the cannula.

  • Patent number: 11376019
    Abstract: Microfracture apparatuses with a cannula and a penetrator. The cannula has a first end, a second end, and a channel extending between the first end and the second end through which a penetrator can move between a retracted and an extended position substantially without rotation of the penetrator. The cannula has a primary portion and a distal portion between the primary portion and the second end, with the distal portion configured such that the distal portion and/or the second end of the channel is disposed at a nonparallel angle relative to the primary portion, for example, with a curve between the primary portion and the distal portion. The penetrator is configured to flex around such a curve and/or to flex to align with the angle of the send end of the channel and/or the distal portion of the cannula.

  • Publication number: 20210402050
    Abstract: A composite medical textile such as a suture includes a plurality of bioresorbable hyaluronan-based fibers and a plurality of non-resorbable fibers. The hyaluronan-based fibers can include at least one of hyaluronic acid, sodium hyaluronate, or the esters of hyaluronic acid such as the benzyl esters. The non-resorbable fibers can be Ultra High Molecular Weight Polyethylene (UHMWPE), and other materials. Methods of making a medical textile are also disclosed.
