The CholangioFlex™ Miniprobe™ is intended to be used during ERCP. Once connected, the CholangioFlex™ is inserted through the lumen of an endoscope or a catheter designed for biliary and pancreatic ducts, with an operating channel or lumen internal diameter higher or equal to 1.0 mm, to provide imaging through direct contact of its dital tip with tissue. 

Important notice: The compatibility between the catheter and the CholangioFlex™ must be checked before the procedure thanks to the compatibility table.

Watch the movie below to learn how to pre-load the AQ-Flex™ 19 in the 19G needle:

The AQ-Flex™ 19 is intended to be used during EUS-FNA procedures. Once connected, the AQ-Flex™ 19 is inserted through the lumen of an endoscopic needle with a diameter higher or equal to 0.91 mm (19 G), to provide imaging through direct contact of its dital tip with tissue. 

Important notice: The use of the locking device is mandatory to lock the AQ-Flex™ 19 in the needle. Thanks to this tool, the Miniprobe™ is blocked and cannot go further than what has been prepared during the pre-loading.

The compatibility between the AQ-Flex™ 19 and the needle must be checked before the procedure thanks to the compatibility table.
