A system and method for repairing soft tissue comprises introducing an instrument having a shaft into an operative site, such as a human shoulder. Then, a flexible grasper is advanced from the instrument to capture a portion of soft tissue. The flexible grasper is then retracted so that the captured tissue lies in a pathway for a needle in the instrument. The needle is advanced along the pathway through the captured tissue, and then a portion of suture is captured with the needle, distally of the captured tissue. The needle is retracted proximally through the captured tissue, to thereby pass the suture therethrough and plicate the tissue. The plicated tissue is then released from the grasper.

A vessel mooring system which includes at least two mooring robots secured to a terminal, each robot includes an attractive force attachment element eg. a vacuum cup and a base structure fixed relative to the terminal.

An expansible anchor is adapted for inserting into a hole formed with a structure. The anchor includes a load cable and a center chock attached to an end of the load cable. At least one side chock resides adjacent to the center chock, and is adapted for movement between an anchor-contracting position and an anchor-expanding position.
