Troubleshooting
(continued from previous page)
Unable to Reverse HeliX Tack
Cause
The HeliX Tack has been advanced to full depth prior to
reversing. Partial placement of the HeliX Tack and verification
of placement is recommended prior to fully driving the HeliX
Tack into tissue.
Twisted Suture
Cause
HeliX Tack's Bearing Eyelet is advanced too far and is not able
to rotate on the Helix.
Suture Breakage
Cause
Suture breaks near biopsy cap and cannot be retrieved for
cinch loading.
Resolution
Ensure the length of catheter from the scope to the assistant is straight.
Pull back on the catheter to assist in reversing, but care should be taken not to disengage driver. If unsuccessful
with pulling, then push catheter forward.
Move the Finger Slider to the "R" position.
Place the entire X-Tack handle in the palm of the assistant's hand.
While securing the finger slider with the thumb and pointer finger in the "R" position, rotate the X-Tack Handle
counterclockwise while ensuring the Finger Slider does not advance while rotating.
If cannot reverse the HeliX Tack, drop HeliX Tack and adjust closure pattern with additional HeliX Tack placements.
Resolution
Attempt to untwist suture with X-Tack driver and scope movement (care should be taken not injure surrounding
tissue with the exposed driver).
If untwisting is unsuccessful, deploy HeliX Tack and adjust closure pattern with additional HeliX Tack placements.
Resolution
Remove the scope liner and retract the scope from patient. If possible, access the suture tail and load the cinch
according to the standard technique.
Insert scope into patient and advance cinch along the outside of the scope to the closure site. Complete cinching
process under direct visualization.
