Endoscopic placement

Placement of Gold Anchor through endoscope in central lung, esophagus, pancreas, and rectal tumors is possible by using Gold Anchor Introducer. Gold Anchor Introducer is delivered pre-loaded with the Gold Anchor marker inside. It comes in a blister single pack, sterilized, ready for use, with the marker length clearly indicated on the package. The Introducer is used to transfer the marker over into a 22G endoscopic ultrasound aspiration needle (“EUS Needle”).

When pushed out of the EUS Needle during implantation, the marker will collapse and fold to different shapes, anchoring immediately in the tissue. The marker can be visualized under ultrasound, magnetic resonance (MRI), computed tomography (CT), fluoroscopy or 2D X-rays at the planning stage and daily during radiotherapy.

The Gold Anchor Introducer is currently available for sale in Europe.

How to transfer the marker

  1. Hold the EUS Needle sheath vertically and place the Introducer on top of the sheath.
  2. Gently insert the EUS Needle sheath all the way to the top of the inspection hole.
  3. Lock the position of the EUS Needle sheath to the Introducer with a steady grip.
  4. Push the stylet of the Introducer all the way to its end position to deploy the marker.

“EUS guided fiducial marker placement (EUS-FP) is an important method to place a fiducial marker safely and precisely especially into pancreatic cancer. Gold Anchor is an ideal marker for EUS-FP as it is easily back loaded into a FNA needle.”
