Suture Placement describes the first half of the RD180™ device function and the process of placing suture through tissue. During Suture Placement, the initial squeeze of the pink lever advances the retracted needle forward through the selected tissue placed in the jaw of the device tip; the full squeeze advances the needle into the ferrule attached to its suture held in the device tip’s distal end. Release of the pink lever retracts the needle, which pulls the now engaged ferrule and suture back through the tissue.

Suture Reset is the term used to describe the second half of the RD180™ device function and the process of rearming the suture into the distal tip. With the device tip oriented for suture reset, a second squeeze of the pink lever advances the needle with its now engaged ferrule and suture forward through the empty jaw into the device tip’s distal end, where a latch feature retains the ferrule and suture. Release of the lever returns the needle back to its retracted position in the distal shaft ready for repeat suture placement.
