Deflux® needle

Sterile and individually packaged disposable product for optimum placement of injectables.

Deflux® Gel is injected using the Deflux® metal needle (3.7 F x 23 G x 350 mm).

Luer-Lock adapter

When attaching the needle to the syringe, bear in mind that the Luer lock adapter engages with the syringe and is only held in place by friction. If too much force is applied, the Luer lock adapter can rotate freely or come loose completely, resulting in an incomplete seal at the needle. For this reason, it is recommended to hold your thumb and index finger firmly around the glass syringe barrel and the Luer lock adapter when assembling the needle and syringe. To facilitate proper insertion/securing of the needle hub and Luer lock adapter, press and twist them firmly together.

Application (Double HIT technique)

Although there are three common procedures for injecting Deflux®, STING, HIT and Double HIT, the Double HIT technique is increasingly the most commonly performed technique for correction of VUR by pediatric urologists in the USA. In 2014, a study showed that 92% of Deflux® treatments used the double HIT technique, which showed higher efficacy rates.

Two reference marks are attached to the needle to ensure correct positioning during the procedure.

1. Double HIT method
2. Algorithm for placing the endoscopic injection needle. The numbers indicate the order of the injection sites. Positions A and B represent the double HIT method. Position C is used less frequently and position D only for complex cases.*
