A nasobiliary drainage catheter (ENBD) placed during ERCP for temporary external drainage of the bile duct through the nasal passage.
At most 10 days. The purpose is temporary extracorporeal diversion, which is why the catheter is the choice when the bile output has to be measured and the duct flushed.
The drainage catheter, the nasal tube, the connection tube and the connector, as a set and separately as parts. All parts are single use, and the probe is placed with an endoscope and a guidewire.
