  • Publication number: 20160157849
    Abstract: Examples of a suture anchor (100) having a non-expandable body (105) and expendable cap (110) are described herein. In response to an axial insertion force that brings the non-expandable body and expendable cap together inside a bone hole, the expendable cap expands radially. This creates a radial force of expansion that advantageously augments an interference fit between the suture anchor and bone hole, which leads to higher fixation strength. Other examples include retention features that inhibit the expendable cap from returning back into its unexpanded state. This advantageously maintains the radial force of expansion against the surrounding pressure of the walls of the bone hole pressing back on the suture.

  • Publication number: 20160143651
    Abstract: In a first embodiment, an instrument guide includes an elongate guide body extending between a proximal end and a distal end, wherein a portion of the guide body extending proximally from the distal end is generally arcuate. The instrument guide further includes a rigid tip extending generally linearly from the distal end of the guide body. The rigid guide further includes a cannulation formed in the guide body and extending continuously from the proximal end of the guide body to a distal terminus of the tip. The cannulation can be approximately uniform in diameter. The instrument guide further includes a cut-out region, different from the guide body cannulation, extending along at least a portion of an inner radial surface of the arcuate body portion and intersecting the guide body cannulation.

  • Publication number: 20150320412
    Abstract: An assembly includes a flexible fixation member, a suture, and a delivery device. The fixation member includes a body with two terminal ends. A suture passes through the flexible fixation member at various points along a length of the body such that portions of the fixation member are slidable relative to the suture and configurable to form a cluster within a surgical site. The delivery device includes a tubular member, an elongated inserter, and a trigger. The elongated inserter is slidably disposed within the tubular member. The inserter has a forked distal end configured to receive a portion of the flexible fixation member and the suture. The trigger is finger-engagable and fixedly coupled to the proximal end of the inserter. It is configured to advance and retract the inserter relative to the tubular member. The trigger includes a retention member for retaining a proximal end portion of the suture.

  • Patent number: 9131958
    Abstract: The present disclosure relates to a seal assembly for a cannula. The cannula includes a housing having a proximal portion and a distal portion. The seal assembly is located in the proximal portion of the housing and includes a first seal including a first tri-slit, a second seal disposed co-axially and proximal to the first seal and including a second tri-slit, and a third seal disposed co-axially to the first seal and the second seal and including a central opening. A cap is coupled to the proximal portion of the housing and adjacent the third seal and includes a plurality of suture retaining features, such as tabs, for management of sutures during surgery. Fluid leakage out of the cannula, during surgery, is substantially reduced due to the leakage being limited to a channel defined by the first tri-slit, the second tri-slit, and the central opening.
