Abstract: A ratcheting inserter device for tensioning a knotless suture anchor includes an outer inserter shaft and an inner inserter shaft having a common longitudinal axis. A ratcheting mechanism provided between the inner inserter shaft and the outer inserter shaft permits rotation of the inner inserter shaft in one direction relative to the outer inserter shaft. The outer inserter shaft has a protrusion at a distal end that is received by an anchor outer sleeve of a suture anchor to prevent relative rotation thereof, and the inner inserter shaft has a projection at the distal end that is received by an inner core 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.

Abstract: A cryogenic fluid distributor for turret machine tools (e.g., lathes) directs a stream of cryogenic fluid from an external, pressurized cryogen source to a working position of a machine tool to prevent overheating of the tool. Designed for easy retrofitting and synchronizing with multi-tool turret machines, the distributor allows for a “dual-fluid” machining capability combining a cryogenic fluid and a conventional cutting fluid (flowing via a conventional coolant system built into a given machine tool). Made of low thermal-mass, insulating polymer and metallic parts, the distributor utilizes the different thermal contraction coefficients of the parts to establish cryogenic sealing connections, which eliminates undesired turret plate cooling and assures rapid cryogen flow start-up.
