  • Patent number: 7211088
    Abstract: A bioabsorbable, cannulated tissue tack having an oblong head is used in sutureless soft tissue fixation to bone, particularly in arthroscopic shoulder surgery. A plurality of ribs are formed along the shaft of the tack. Repair of the glenohumeral joint is performed by installing the tack through a hole formed through the soft tissue of the labrum and into the cancellous bone of the glenoid rim. Aligning the oblong head of the tack lengthwise along the glenoid rim provides a low profile that avoids articular impingement on the tack head.
    Type: Grant
    Filed: September 30, 2003
    Date of Patent: May 1, 2007
    Assignee: Arthrex, Inc.
