Title:
RATCHETING INSERTER DEVICE AND SUTURE ANCHOR ARRANGEMENT
Document Type and Number:
WIPO Patent Application WO/2014/149609
Kind Code:
A3
Abstract:
A ratcheting inserter device (24) for tensioning a knotless suture anchor (22) includes an outer inserter shaft (26) and an inner inserter shaft (40) having a common longitudinal axis. A ratcheting mechanism (54) provided between the inner inserter shaft and the outer inserter permits rotation of the inner inserter shaft in one direction relative to the outer inserter shaft. The outer inserter shaft has a protrusion (50) at a distal end (28) that is received by an anchor outer sleeve (80) of a suture anchor to prevent relative rotation thereof, and the inner inserter shaft has a projection (48) at the distal end that is received by an inner core (110) of the anchor for rotational movement therewith. The ratcheting inserter device rotates the inner core of the suture anchor to spool and tension suture thread. Thereafter, the ratcheting mechanism is disengaged and the inner inserter shaft is forced axially into the anchor outer sleeve.
