Use of the remOVE DC Cutter

The remOVE DC Cutter is a bipolar endoscopic instrument which allows the fragmentation of OTSC® and FTRD® clips in the digestive tract when used in combination with a remOVE DC Impulse.

The remOVE DC Cutter

The remOVE DC Cutter consists of an insulated conducting wire with an exposed tip intended to be passed through the working channel of an endoscope. It is intended to conduct the direct current (DC) supplied by the remOVE DC Impulse, to a previously implanted clip, whereby separation of the clip occurs through resistive heating.

The remOVE DC Cutter is designed to be used only with the remOVE DC Impulse and flexible endoscopes.

The remOVE DC Cutter is part of the remOVE DC Cutter Set.

Application of the remOVE DC Cutter

Step 1: Introduce the remOVE DC Cutter through working channel and establish contact with the clip. When a continuous acoustic signal occurs, press the foot-activated switch once in order to cut the clip. Repeat the procedure at a point of the clip opposite of the first cut.

Step 2: Make sure by endoscopic visualization that fragmentation of the clip at two spots has been successfully accomplished.

Step 3: Mount the remOVE SecureCap onto the endoscope tip. Use the remOVE Grasper to pull the clip fragments into the remOVE SecureCap and remove it from the patient’s body.

Important notes:

Before application the endoscope has to be protected using the remOVE Shield.
